Model and Application

Complete model RPS-500-15-C
Construction -C: enclosed, without built-in fan.
System configuration Class I with protective ground (FG); this enclosed version is not suitable for a Class II system without FG.
Typical applications Oral irrigators, hemodialysis machines, medical computer monitors, sleep-apnea devices, pumps and electric beds.

Suitable for BF applications with appropriate system design. Component medical approvals do not certify the finished equipment; assess isolation, leakage current, grounding and EMC at system level.

Output Ratings

Nominal main output 15 V.
Main current with specified cooling 33.3 A with 25 CFM external airflow.
Main rated power with specified cooling 499.5 W with 25 CFM external airflow.
Natural-convection main current 20.7 A.
Natural-convection rated power 310.5 W; apply the separate 115 VAC / 230 VAC thermal curves.

Line / load regulation ±0.5% / ±1.0%.
Efficiency, typical 92%.

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.

Input, Timing and Leakage

Input range 80–264 VAC or 113–370 VDC; low-input derating applies.
Input frequency 47–63 Hz.
Power-factor correction Built-in active PFC; PF >0.94 at 230 VAC and >0.98 at 115 VAC, full load.
AC current, typical 5.8 A at 115 VAC; 2.9 A at 230 VAC.
Cold-start inrush, typical 40 A at 115 VAC; 80 A at 230 VAC.
Set-up and rise time 1000 ms set-up / 30 ms rise at 230 VAC; 1500 ms / 30 ms at 115 VAC, full load.
Hold-up time, typical 10 ms at either 230 VAC or 115 VAC, full load.
Earth leakage current Less than 220 µA at 264 VAC, 50 Hz.
Touch current Less than 100 µA at 264 VAC, measured from primary input to DC output.
Low-power condition Less than 0.5 W using PS-ON control; this is not an unconditional main-output-on no-load figure.
Block-diagram frequencies PFC: 90 kHz; PWM: 100 kHz.

Protection

Short circuit / overload 105–135% of rated output power; hiccup mode, with automatic recovery after the fault is removed.
Overvoltage threshold 16.5–19.5 V.
Overvoltage response Hiccup mode; automatically recovers after the fault is removed.
Overtemperature Output shuts down and automatically recovers after the temperature falls.

Protection thresholds are not an increased operating-power allowance.

Standby, Control and Status

5 V standby 5 V at up to 0.6 A without a fan, or 1 A with 25 CFM; tolerance ±2%, ripple/noise 120 mVp-p maximum. Observe the cooling condition rather than treating 1 A as unconditional.
PS-ON High, 2–5 V: main output on. Low, 0–0.5 V: main output off. CN95 pin 3 is PS-ON; pins 2 and 4 are DC COM.
Power Good / Power Fail The TTL status 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 value. The available status connection is CN11 pin 4 PG, referenced to pin 3 DC COM; no separate PF pin is assigned.
Remote sense CN11 pin 1 −S and pin 2 +S. Connect the sense lines with correct polarity according to the manufacturer instructions; no maximum compensation voltage is stated here.
Power indication LED power-on indicator.
Fan auxiliary output 12 V at up to 0.5 A for driving a fan; tolerance −15% to +10% at 20% main-output rated current with 25 CFM. CN12 pin 1 DC COM, pin 2 +12 V.

Derating and Environment

Ambient range −30 to +70°C, subject to the applicable cooling-mode curve.
Horizontal-mounting thermal limits At 230 VAC with natural convection: 310 W through 30°C, 300 W at 40°C, 250 W at 50°C and 200 W at 60°C. At 115 VAC: 310 W through 30°C, 240 W at 45°C, 220 W at 50°C and 160 W at 60°C. The no-fan curves end at 60°C. With 25 CFM: the family curve shows 500 W through 50°C, falling to 250 W at 70°C.
Input-voltage curve, 60 Hz 70% load at 80 VAC, 80% at 90 VAC, reaching 100% at 115 VAC and remaining at 100% through 264 VAC.
Operating altitude Up to 4000 m. Above 2000 m, reduce allowable ambient temperature by 3.5°C per additional 1000 m for fanless operation, or 5°C per additional 1000 m for fan-cooled operation.
Working humidity 20–90% RH, non-condensing.
Storage temperature −40 to +85°C.
Temperature coefficient ±0.03%/°C over 0–50°C.
Vibration 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes along each X, Y and Z axis.

The thermal graphs use rounded family power levels; retain the exact model current and rated-power limits above and use the more restrictive applicable limit. Combine input-voltage, temperature and altitude derating. Do not extrapolate a no-fan curve beyond its plotted endpoint.
