Model and Application
Complete model
RPS-200-12.
Series and construction
RPS-200 medical AC/DC power supply; PCB open-frame construction.
Voltage code
12 specifies the nominal DC output voltage.
System class
Suitable for Class I systems with FG or Class II systems without FG, subject to the model-specific EMC conditions below.
Medical application
Primary-to-secondary 2 MOPP. Suitable for BF applications only with appropriate system consideration; final equipment compliance remains an integration requirement.
Catalogue applications include oral irrigators, hemodialysis machines, medical monitors, sleep-apnea devices and pumps. Electric beds are also listed for this series.
DC Output and Load Conditions
Nominal output
12 V.
Convection rating
11.7 A; catalogue-rated 140.4 W.

16.7 A; catalogue-rated 200.4 W.
Adjustment range
11.4–12.6 V, using SVR1.
Ripple and noise, maximum
100 mVp-p.
Voltage tolerance
±2.0%; includes setup tolerance, line regulation and load regulation.
Line regulation
±0.5%.
Load regulation
±1.0%.
Efficiency, typical
93%.
The higher rating requires 10 CFM forced airflow. The convection rating applies without that forced airflow; do not treat the two ratings as interchangeable.
Do not exceed the applicable voltage, current or catalogue-rated power limit. Combine the cooling, input-voltage and ambient-temperature limits. Ripple is measured at 20 MHz with a 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors.
Input, Start-Up and Consumption
Input range
80–264 VAC or 113–370 VDC; low-input derating applies.
Frequency
47–63 Hz.
AC input current, typical
2 A at 115 VAC; 1 A at 230 VAC.
Cold-start inrush, typical
30 A at 115 VAC; 60 A at 230 VAC.
No-load consumption
Less than 0.5 W.
Set-up and rise
700 ms setup and 30 ms rise at both 230 VAC and 115 VAC, full load.
Hold-up, typical
16 ms at 230 VAC; 16 ms at 115 VAC, full load.
Leakage at 264 VAC
Earth leakage <180 µA; touch current <40 µA. Touch current is measured from primary input to DC output.
Switching-frequency diagram
65 kHz.
Power factor
Built-in active PFC; PF >0.94 at 230 VAC and >0.98 at 115 VAC, full load.
Unless separately stated, parameters are measured at 230 VAC, rated load and 25°C ambient.
Protection
Short circuit and overload
Short-circuit protection is listed. Overload operates at 110–140% of rated output power; hiccup mode recovers automatically after the fault is removed.
Overvoltage threshold
13.2–15.6 V.
Overvoltage response
Output shuts down; re-power on to recover.
Overtemperature response
Output shuts down. Re-power on to recover.
Cooling and Derating
Ambient range
−30 to +70°C, with derating; horizontal mounting.
Convection temperature curve
The graph shows 70% load from −30 to 45°C, falling to 40% at 70°C. Use the model-specific convection current and wattage above.
Input-voltage curve, 60 Hz
80 VAC: 70%; 115 VAC: 100%, maintained to 264 VAC. The curve is explicitly for 10 CFM operation.
10 CFM temperature curve
100% load from −30 to 50°C, falling to 40% at 70°C.
Fan arrangement
The mechanical drawing positions an external 10 CFM fan 5 cm from the assembly in the indicated airflow direction; preserve that airflow path. A fan is not claimed as supplied.
Use the complete plotted curves for intermediate conditions; the maximum ambient temperature is a derated point. Apply the most restrictive simultaneous limit.
Environment
Operating humidity
20–90% RH, non-condensing.
Storage
−40 to +85°C; 10–95% RH, non-condensing.

±0.03%/°C over 0–50°C.
Vibration
10–500 Hz, 2 G; 10 minutes per cycle, 60 minutes each along X, Y and Z.
Operating altitude
5,000 m.
High-altitude derating
Above 2,000 m, reduce allowed ambient temperature by 3.5°C per 1,000 m for fanless operation or 5°C per 1,000 m for fan-cooled operation.
Dimensions and Installation
Dimensions, L × W × H
101.6 × 50.8 × 29 mm. General drawing tolerance ±1 mm.
Mounting geometry
Four 3.3 mm mounting holes on a 95.25 × 44.45 mm pattern; 3.175 mm edge offsets; underside projection 3 mm maximum. Follow the complete PCB drawing.
Adjustment
Use SVR1 within the stated voltage-adjustment range.
