MEAN WELL RPT-75 series: Triple-Output Medical AC/DC Power Supply - RPT-75C

Description

MEAN WELL RPT-75C is a triple-output, open-frame medical AC/DC power supply with 5 V / 15 V / -15 V outputs and 72 W combined rated output power. The higher 100 W rating requires 23.5 CFM forced airflow; apply the model-specific output limits and thermal curves.

The RPT-75 section is on PDF pages 14, 15, 16, 17, 18. Refer to the complete mechanical drawings and notes when planning installation.

Model and Selection

Complete model RPT-75C. The suffix identifies the three-output voltage combination; all three channels belong to one power supply.
Construction and use 5 × 3-inch PCB footprint; Class I installation with protective earth. Medical applications include oral irrigators, hemodialysis equipment, medical monitors and sleep-apnea devices. BF use requires appropriate consideration in the complete system.
Combined power limit 72 W total across CH1–CH3 at rated conditions. Respect each channel current, its minimum load, the combined power limit and the derating curves simultaneously.

CH1 Output

Nominal DC voltage 5 V relative to COM; retain the indicated polarity.
Rated current 6 A.
Current range 0.6–8 A. The lower bound is the specified minimum load; the upper bound does not override the combined power or cooling limits.
Ripple and noise, maximum 80 mVp-p.
Voltage tolerance ±2.0%, including set-up tolerance, line regulation and load regulation.
Line regulation ±0.5%.
Load regulation ±1.5%.

CH2 Output

Nominal DC voltage 15 V relative to COM; retain the indicated polarity.
Rated current 2.3 A.
Current range 0.1–3 A. The lower bound is the specified minimum load; the upper bound does not override the combined power or cooling limits.
Ripple and noise, maximum 120 mVp-p.
Voltage tolerance ±8.0%, including set-up tolerance, line regulation and load regulation.
Line regulation ±1.0%.
Load regulation ±3.0%.

CH3 Output

Nominal DC voltage -15 V relative to COM; retain the indicated polarity.
Rated current 0.5 A.
Current range 0.1–1 A. The lower bound is the specified minimum load; the upper bound does not override the combined power or cooling limits.
Ripple and noise, maximum 80 mVp-p.
Voltage tolerance ±5.0%, including set-up tolerance, line regulation and load regulation.
Line regulation ±1.0%.
Load regulation ±1.0%.

Output Loading and Measurement

Combined rated output power 72 W.
Higher output with forced cooling 100 W total with 23.5 CFM airflow. The specification labels this row “PEAK LOAD (23.5 CFM)”; use it with the forced-air thermal curve.
Efficiency, typical 77%.
CH1 voltage adjustment 4.75–5.5 V.

Values are measured at 230 VAC, rated load and 25°C unless otherwise stated. Ripple/noise is measured at 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.

The higher rating is cooling-dependent. No 10-second or 33% duty rule is stated for this series; do not substitute another series’ peak-time rule. The family thermal diagram uses 72 W and 100 W reference labels; use this exact model’s combined wattages above.

Input and Timing

Input voltage and frequency 90–264 VAC or 127–370 VDC; 47–63 Hz AC. Apply the input derating curve.
Input current, typical 1.5 A at 115 VAC; 1 A at 230 VAC.
Cold-start inrush, typical 25 A at 115 VAC; 50 A at 230 VAC.
Set-up / rise time 500 ms / 30 ms at both 230 VAC and 115 VAC, full load.
Hold-up time, typical 90 ms at 230 VAC; 20 ms at 115 VAC, full load.
Leakage current Earth leakage <150 µA at 264 VAC; touch current <100 µA at 264 VAC, measured from primary input to DC output.

Set-up and rise-time figures use a cold first start. Repeated rapid on/off operation can increase the set-up time.

Protection

Short circuit and overload Overload at 140–180% of rated output power. Hiccup protection recovers automatically after the fault is removed.
CH1 overvoltage 5.7–6.8 V; output shuts down and requires re-power on to recover.

Cooling and Environment

Temperature operating range −20 to 70°C, subject to the cooling and load curves.
Horizontal natural-convection curve 100% load from −20°C through 40°C, decreasing to 50% at 60°C. The natural-convection curve ends at 60°C.
23.5 CFM thermal curve The family diagram holds the 133% reference level from −20°C through 50°C, then slopes to 50% at 70°C. Apply the exact model’s higher wattage limit and all channel limits as well.
Input-voltage curve at 60 Hz 80% load at 90 VAC, rising to 100% at 100 VAC and remaining at 100% through 264 VAC.
Operating altitude Up to 3000 m. Above 2000 m, reduce the permissible ambient temperature by 3.5°C per 1000 m for fanless operation or 5°C per 1000 m for fan-cooled operation.
Humidity Operating: 20–90% RH, non-condensing. Storage: −40 to +85°C, 10–95% RH, non-condensing.
Temperature coefficient ±0.03%/°C over 0–45°C.
Vibration 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes along each of the X, Y and Z axes.

Apply input-voltage, ambient-temperature and combined-output limits together. Do not interpret one curve as permission to exceed another applicable limit.

Safety and Insulation

Medical safety approvals IEC 60601-1:2005 + A1 + A2; TUV BS EN/EN 60601-1:2006 + A1 + A12 + A2; ANSI/AAMI ES60601-1:2005 + A2; CAN/CSA-C22.2 No. 60601-1:2014 + A2; EAC TP TC 004.
Other safety scope Design refers to BS EN/EN 60335-1 by request; not represented as an unconditional approval.
Isolation level Primary to secondary: 2 MOPP; primary to earth: 1 MOPP.
Withstand voltage Input/output: 4 kVAC; input/FG: 2 kVAC; output/FG: 1.5 kVAC.
Insulation resistance 100 MΩ at 500 VDC, 25°C and 70% RH for input/output, input/FG and output/FG.

These are power-supply component ratings. Medical BF suitability and regulatory compliance must be assessed in the finished equipment and its actual installation.

Radiated RF IEC 61000-4-3: 10 V/m, 80 MHz–2.7 GHz, level 3; the medical table-9 tests use 9–28 V/m at 385 MHz–5.78 GHz.
EFT and surge IEC 61000-4-4: 2 kV, level 3. IEC 61000-4-5: 4 kV line-to-FG / 2 kV line-to-line, level 4.
Conducted RF and magnetic field IEC 61000-4-6: 10 V, level 3. IEC 61000-4-8: 30 A/m, level 4.
Dips and interruptions IEC 61000-4-11: voltage dips of 100% for 1 period and 30% for 25 periods; interruptions of 100% for 250 periods.

The EMC test mounts the power supply on a 360 × 360 × 1 mm metal plate. Reconfirm EMC in the complete equipment; the component test does not replace finished-system testing.

Mechanical Installation

Overall dimensions 127 × 76.2 × 31 mm (L × W × H). General drawing tolerance: ±1 mm.
Mounting holes 4 × Ø3.8 mm; 115.8 × 64.75 mm centre spacing; 5.6 mm and 5.7 mm edge offsets. Use the full mechanical drawing for locations; the underside drawing shows 3 mm maximum.
Protective earth M1 is the safety-grounding point. M1 and M2 should have secure electrical contact with chassis ground for better EMC.
Heat-sink caution Do not short HS1, HS2, HS3.
Input fuses FS1 and FS2: T2.5 A / 250 V AC.

For the higher forced-air rating, the mechanical drawing places a fan delivering at least 23.5 CFM 15 cm from the PCB and centred along its long side. Follow the illustrated airflow arrangement.

Connector and terminal references identify the mating components shown in the catalogue. They are not a statement that loose housings, terminals, cables or an external fan are included. Select the full VHR housing reference to match the circuit count and wire assembly shown in the drawing.

Reliability and Weight

MTBF 2305.8 thousand hours, Telcordia SR-332; 521.3 thousand hours, MIL-HDBK-217F at 25°C.
Series lifetime feature The catalogue lists a lifetime greater than 140,000 hours; this feature is separate from the stated MTBF methods.
Catalogue single-unit weight 250 g, taken from the first per-unit value in PACKING; a catalogue reference, not a measured shipping weight.
Packing reference 0.25 kg per unit; 63 pieces / 17.3 kg / 1.28 CUFT.
Manufacturer warranty The manufacturer datasheet lists a three-year warranty. Applicable manufacturer terms govern; this is not an additional seller warranty promise.
