Ripple and noise, maximum 200 mVp-p. Voltage tolerance ±2.0%; includes set-up tolerance, line and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 93%. Use the individual main-output current and power limits together with the cooling, input-voltage and ambient-temperature limits. The 5 V standby and fan-rail ratings are separate interface limits; they do not authorize adding extra watts to the stated main-output or peak rating. These pages provide no separate combined-output power formula. Unless otherwise stated, specifications are measured at 230 VAC, rated load and 25°C. Ripple/noise is measured with 20 MHz bandwidth using a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors.

  MEAN WELL RPS-400 series: Medical AC/DC Power Supply with Side Fan - RPS-400-48-SF

  MEAN WELL RPS-400-48-SF is a 48 V medical AC/DC power supply in the enclosed casing with a side fan configuration. It supplies 8.4 A / 403.2 W with its fitted fan. Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-48-SF. SF: Enclosed casing with a side fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 48 V. Forced-air current and power 8.4 A / 403.2 W; Built-in side fan. Cooling configuration This SF version is rated with its built-in fan. The type-selection table does not assign a fanless convection mode to TF/SF. Ripple and noise, maximum 200 mVp-p. Main-output voltage adjustment 45.6–50.4 V. Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 94%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 52.8–62.4 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. The external CN12 fan connector is excluded for TF/SF. The built-in fan control is specified as fan-on by 20% load minimum for TF/SF. Preserve the fitted fan and its airflow direction. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit. Follow the complete connection and installation instructions. CN95: TKP DH2L-2X2 or equivalent; pin 1 5Vsb, pins 2 and 4 DC COM, pin 3 PS-ON. Both CN11 and CN95 list TKP DH2 or equivalent mating housings and TKP or equivalent terminals; the catalogue does not provide a more complete terminal ordering suffix. Cooling, Derating and Environment Horizontal temperature/load curves With its built-in fan, the horizontal TF/SF curve holds nominal 400 W from −30 to 50°C, then falls to 150 W at 70°C. The catalogue does not provide a fanless convection mode for this version. Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, rising to 100% at 115 VAC and remaining at 100% through 264 VAC. Working ambient / humidity −30 to +70°C with derating; 20–90% RH, non-condensing. Convection curves for PCB/C end at 60°C; the 70°C point requires the plotted forced-air configuration. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle and 60 minutes each along X, Y and Z. Altitude Operating altitude up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. The plotted curves use nominal series-level wattages. Apply them together with this exact model’s voltage/current/power ratings, its installed cooling arrangement and input derating; neither the curve nor the upper temperature permits exceeding the model rating. Dimensions and Installation Dimensions, L × W × H 160 × 86 × 43 mm; case 248A. Mounting and clearance Bottom: four M3 holes on a 120 × 50 mm pattern, maximum penetration 2 mm (hole group 1). Use 4–6 kgf·cm mounting torque and the complete bottom-view offsets. Airflow The fitted side fan airflow direction is shown in the SF mechanical drawing; preserve the side clearance and airflow path. Board and adjustment references SVR1 is the main-output adjustment reference. FS1 is marked F8A/250V. HS1, HS2, HS3 and HS4 must not be shorted. Drawing units are millimetres with general tolerance ±1 mm unless separately marked. Use the full model-specific mechanical drawing for offsets and clearances; included screws, loose connectors and installation hardware are not stated.

  MEAN WELL RPS-400 series: Medical AC/DC Power Supply with Side Fan - RPS-400-36-SF

  MEAN WELL RPS-400-36-SF is a 36 V medical AC/DC power supply in the enclosed casing with a side fan configuration. It supplies 11.2 A / 403.2 W with its fitted fan. Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-36-SF. SF: Enclosed casing with a side fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 36 V. Forced-air current and power 11.2 A / 403.2 W; Built-in side fan. Cooling configuration This SF version is rated with its built-in fan. The type-selection table does not assign a fanless convection mode to TF/SF. Ripple and noise, maximum 200 mVp-p. Main-output voltage adjustment 34.2–37.8 V. Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 94%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 39.6–46.8 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. The external CN12 fan connector is excluded for TF/SF. The built-in fan control is specified as fan-on by 20% load minimum for TF/SF. Preserve the fitted fan and its airflow direction. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit. Follow the complete connection and installation instructions. CN95: TKP DH2L-2X2 or equivalent; pin 1 5Vsb, pins 2 and 4 DC COM, pin 3 PS-ON. Both CN11 and CN95 list TKP DH2 or equivalent mating housings and TKP or equivalent terminals; the catalogue does not provide a more complete terminal ordering suffix. Cooling, Derating and Environment Horizontal temperature/load curves With its built-in fan, the horizontal TF/SF curve holds nominal 400 W from −30 to 50°C, then falls to 150 W at 70°C. The catalogue does not provide a fanless convection mode for this version. Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, rising to 100% at 115 VAC and remaining at 100% through 264 VAC. Working ambient / humidity −30 to +70°C with derating; 20–90% RH, non-condensing. Convection curves for PCB/C end at 60°C; the 70°C point requires the plotted forced-air configuration. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle and 60 minutes each along X, Y and Z. Altitude Operating altitude up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. The plotted curves use nominal series-level wattages. Apply them together with this exact model’s voltage/current/power ratings, its installed cooling arrangement and input derating; neither the curve nor the upper temperature permits exceeding the model rating. Dimensions and Installation Dimensions, L × W × H 160 × 86 × 43 mm; case 248A. Mounting and clearance Bottom: four M3 holes on a 120 × 50 mm pattern, maximum penetration 2 mm (hole group 1).

  MEAN WELL RPS-400 series: Medical AC/DC Power Supply with Side Fan - RPS-400-18-SF

  MEAN WELL RPS-400-18-SF is an 18 V medical AC/DC power supply in the enclosed casing with a side fan configuration. It supplies 22.3 A / 401.4 W with its fitted fan. Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-18-SF. SF: Enclosed casing with a side fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 18 V. Forced-air current and power 22.3 A / 401.4 W; Built-in side fan. Cooling configuration This SF version is rated with its built-in fan. The type-selection table does not assign a fanless convection mode to TF/SF. Ripple and noise, maximum 150 mVp-p. Main-output voltage adjustment 17.1–18.9 V. Voltage tolerance ±3.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 93%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 19.8–23.4 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. The external CN12 fan connector is excluded for TF/SF. The built-in fan control is specified as fan-on by 20% load minimum for TF/SF. Preserve the fitted fan and its airflow direction. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit. Follow the complete connection and installation instructions. CN95: TKP DH2L-2X2 or equivalent; pin 1 5Vsb, pins 2 and 4 DC COM, pin 3 PS-ON. Both CN11 and CN95 list TKP DH2 or equivalent mating housings and TKP or equivalent terminals; the catalogue does not provide a more complete terminal ordering suffix. Cooling, Derating and Environment Horizontal temperature/load curves With its built-in fan, the horizontal TF/SF curve holds nominal 400 W from −30 to 50°C, then falls to 150 W at 70°C. The catalogue does not provide a fanless convection mode for this version. Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, rising to 100% at 115 VAC and remaining at 100% through 264 VAC. Working ambient / humidity −30 to +70°C with derating; 20–90% RH, non-condensing. Convection curves for PCB/C end at 60°C; the 70°C point requires the plotted forced-air configuration. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle and 60 minutes each along X, Y and Z. Altitude Operating altitude up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. The plotted curves use nominal series-level wattages. Apply them together with this exact model’s voltage/current/power ratings, its installed cooling arrangement and input derating; neither the curve nor the upper temperature permits exceeding the model rating. Dimensions and Installation Dimensions, L × W × H 160 × 86 × 43 mm; case 248A. Mounting and clearance Bottom: four M3 holes on a 120 × 50 mm pattern, maximum penetration 2 mm (hole group 1). Use 4–6 kgf·cm mounting torque and the complete bottom-view offsets. Airflow The fitted side fan airflow direction is shown in the SF mechanical drawing; preserve the side clearance and airflow path. Board and adjustment references SVR1 is the main-output adjustment reference. FS1 is marked F8A/250V. HS1, HS2, HS3 and HS4 must not be shorted. Drawing units are millimetres with general tolerance ±1 mm unless separately marked. Use the full model-specific mechanical drawing for offsets and clearances; included screws, loose connectors and installation hardware are not stated.

Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-48-TF. TF: Enclosed casing with a top fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 48 V. Forced-air current and power 8.4 A / 403.2 W; Built-in top fan. Cooling configuration This TF version is rated with its built-in fan. The type-selection table does not assign a fanless convection mode to TF/SF. Ripple and noise, maximum 200 mVp-p. Main-output voltage adjustment 45.6–50.4 V. Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 94%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 52.8–62.4 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. The external CN12 fan connector is excluded for TF/SF. The built-in fan control is specified as fan-on by 20% load minimum for TF/SF. Preserve the fitted fan and its airflow direction. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit.

Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 16.5–19.5 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. The external CN12 fan connector is excluded for TF/SF. The built-in fan control is specified as fan-on by 20% load minimum for TF/SF. Preserve the fitted fan and its airflow direction. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit.

It supplies 7 A / 252 W by convection or 11.2 A / 403.2 W with 25 CFM airflow. Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-36-C. C: Enclosed casing without a built-in fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 36 V. Forced-air current and power 11.2 A / 403.2 W; 25 CFM external airflow. Convection current and power 7 A / 252 W, subject to the input-voltage and temperature curves. Ripple and noise, maximum 200 mVp-p. Main-output voltage adjustment 34.2–37.8 V. Voltage tolerance ±1.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 94%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 39.6–46.8 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. Use the dedicated CN12 polarity below. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit. Follow the complete connection and installation instructions. CN95: TKP DH2L-2X2 or equivalent; pin 1 5Vsb, pins 2 and 4 DC COM, pin 3 PS-ON. Both CN11 and CN95 list TKP DH2 or equivalent mating housings and TKP or equivalent terminals; the catalogue does not provide a more complete terminal ordering suffix. Cooling, Derating and Environment Horizontal temperature/load curves The convection curve uses nominal 250 W up to 35°C at 115 VAC, then 130 W at 60°C; at 230 VAC it holds 250 W to 40°C, then 160 W at 60°C. With 25 CFM, the plotted nominal 400 W holds to 50°C and falls to 200 W at 70°C. Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, rising to 100% at 115 VAC and remaining at 100% through 264 VAC. Working ambient / humidity −30 to +70°C with derating; 20–90% RH, non-condensing. Convection curves for PCB/C end at 60°C; the 70°C point requires the plotted forced-air configuration. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle and 60 minutes each along X, Y and Z. Altitude Operating altitude up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation. The plotted curves use nominal series-level wattages. Apply them together with this exact model’s voltage/current/power ratings, its installed cooling arrangement and input derating; neither the curve nor the upper temperature permits exceeding the model rating. Dimensions and Installation Dimensions, L × W × H 130 × 86 × 43 mm; case 247A. Mounting and clearance Bottom: four M3 holes, 120 × 50 mm pattern, maximum penetration 2 mm (hole group 1).

  MEAN WELL RPS-400 series: Medical AC/DC Power Supply, Enclosed - RPS-400-18-C

  MEAN WELL RPS-400-18-C is an 18 V medical AC/DC power supply in the enclosed casing without a built-in fan configuration. It supplies 13.9 A / 250.2 W by convection or 22.3 A / 401.4 W with 25 CFM airflow. Select the installation class, load and operating temperature using the version-specific limits below. Product Datasheet Download MEAN WELL RPS-400 Datasheet (PDF) The RPS-400 section is on PDF pages 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. Refer to the complete mechanical drawings and notes when planning installation. Model and Configuration Complete model RPS-400-18-C. C: Enclosed casing without a built-in fan. System class This enclosed version is not suitable for a Class II system without FG; use the Class I arrangement with FG. Integration use Medical power conversion for applications such as oral irrigators, hemodialysis equipment, medical monitors, sleep-apnea devices, pumps and electric beds. BF use requires appropriate complete-system consideration. Main DC Output Nominal main output 18 V. Forced-air current and power 22.3 A / 401.4 W; 25 CFM external airflow. Convection current and power 13.9 A / 250.2 W, subject to the input-voltage and temperature curves. Ripple and noise, maximum 150 mVp-p. Main-output voltage adjustment 17.1–18.9 V. Voltage tolerance ±3.0%, including set-up tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±1.0%. Efficiency, typical 93%. Use the exact model ratings above; the series designation is not a substitute for its printed wattage. Forced-air ratings are cooling-dependent continuous ratings, not an unrestricted overload or peak-power allowance. Unless specified otherwise, values are measured at 230 VAC, rated load and 25°C. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Input and Timing Input range 80–264 VAC or 113–370 VDC; 47–63 Hz AC. Apply the input derating curve. Power factor Built-in active PFC; at full load, PF >0.94 at 230 VAC and >0.98 at 115 VAC. Input current, typical 4.2 A at 115 VAC; 2.1 A at 230 VAC. Cold-start inrush, typical 35 A at 115 VAC; 70 A at 230 VAC. Set-up / rise time 1000 ms / 30 ms at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load. Hold-up time, typical 16 ms at both 230 VAC and 115 VAC, full load. Leakage current Earth leakage <200 µA at 264 VAC / 50 Hz; touch current <70 µA at 264 VAC, measured from primary input to DC output. No-load power Less than 0.5 W by PS-ON control. Protection and Auxiliary Outputs Short circuit / overload Short-circuit protection; overload at 105–135% of rated output power. Hiccup mode recovers automatically after the fault is removed. Overvoltage Threshold 19.8–23.4 V; output shuts down and requires re-power on to recover. Overtemperature Output shuts down and recovers automatically after temperature decreases. 5 V standby 5 V, 0.6 A without a fan or 1 A with 25 CFM; tolerance ±2%, maximum ripple 120 mVp-p. These are cooling-qualified standby limits. 12 V fan supply 12 V / 0.5 A for driving a fan. Tolerance −15% to +10% at 35% main-output rated current with 25 CFM. Use the dedicated CN12 polarity below. Control, Status and Remote Sense PS-ON high (2–5 V) turns the main output on; low (0–0.5 V) turns it off. The PG TTL signal goes high 10–500 ms after power set-up and goes low at least 1 ms before output falls below 90% of its rated voltage, providing the listed power-good/power-fail indication. CN11: TKP DH2I-2X2 or equivalent; pin 1 −S, pin 2 +S, pin 3 DC COM, pin 4 PG. The −S/+S pins are the remote-sense connections; this section does not specify a numerical cable-drop compensation limit. Follow the complete connection and installation instructions. CN95: TKP DH2L-2X2 or equivalent; pin 1 5Vsb, pins 2 and 4 DC COM, pin 3 PS-ON. Both CN11 and CN95 list TKP DH2 or equivalent mating housings and TKP or equivalent terminals; the catalogue does not provide a more complete terminal ordering suffix. Cooling, Derating and Environment Horizontal temperature/load curves The convection curve uses nominal 250 W up to 35°C at 115 VAC, then 130 W at 60°C; at 230 VAC it holds 250 W to 40°C, then 160 W at 60°C. With 25 CFM, the plotted nominal 400 W holds to 50°C and falls to 200 W at 70°C. Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, rising to 100% at 115 VAC and remaining at 100% through 264 VAC. Working ambient / humidity −30 to +70°C with derating; 20–90% RH, non-condensing. Convection curves for PCB/C end at 60°C; the 70°C point requires the plotted forced-air configuration. Storage −40 to +85°C; 10–95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C over 0–50°C. Vibration: 10–500 Hz, 2 G, 10 minutes per cycle and 60 minutes each along X, Y and Z. Altitude Operating altitude up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation.
