Model-Specific DC Output
| Rated output voltage |
24 V. |
| Rated output current |
40 A; load range 0–40 A. |
| Rated output power |
960 W. |
| Ripple and noise, maximum |
200 mVp-p. |
| Built-in voltage adjustment |
23.2–24.8 V. |
| Voltage tolerance |
±1.0%; includes set-up, line and load regulation. |
| Line / load regulation |
±0.5% / ±0.5%. |
| Typical efficiency |
87% at 230 VAC and rated load. |
The current and power limits apply together. Voltage adjustment or programming does not increase the permitted continuous output power; apply the input and temperature derating limits.
Input, Timing and Low-Line Limits
| Input voltage |
90–264 VAC or 127–370 VDC. |
| AC frequency |
47–63 Hz. |
| Typical AC input current |
10.5 A at 115 VAC; 5.5 A at 230 VAC. |
| Input power factor |
Built-in active PFC. |
| Cold-start inrush current |
50 A. |
| Leakage current |
Less than 1.1 mA at 230 VAC. |
| Set-up / rise time |
1000 / 60 ms at 230 VAC, full load. |
| Typical hold-up time |
16 ms at 230 VAC, full load. |
The input-voltage load curve reaches 100% at 100 VAC and remains there through 264 VAC.
Printed low-line limits for this voltage model: 90 VAC: 864 W maximum and 36 A maximum. Apply these together with the temperature curve.
Protection and Cooling
| Short-circuit / overload protection |
105–125% of rated output power; constant-current limiting, with automatic recovery after the fault is removed. |
| Overvoltage protection |
26.4–32.4 V; output shutdown, re-power to recover. |
| Overtemperature protection |
Output shutdown; automatic recovery after the temperature falls. |
| Cooling |
Built-in DC fan with fan-speed control. Keep the fan inlet and connector-end exhaust unobstructed. |
| Hot-swap isolation |
Built-in OR-ing diode supports hot-swap operation in the compatible rack system. |
Temperature and Environmental Limits
| Working temperature |
-20°C to 60°C; subject to the load curve. |
| Working humidity |
20–90% RH, non-condensing. |
| Storage temperature / humidity |
-40°C to +85°C; 10–95% RH, non-condensing. |
| Temperature coefficient |
±0.02%/°C from 0°C to +50°C. |
| Vibration |
10–500 Hz, 2 G, 10-minute cycle; 60 minutes each along X, Y and Z. |
The curve permits 100% load from -20°C to +50°C, derating to 60% at +60°C.
Above 2000 m altitude, reduce the allowed ambient temperature by 5°C per 1000 m for these fan-cooled supplies. The general altitude derating note does not replace installation or safety limits.
The efficiency-versus-load graph is for the 48 V model at 230 VAC; the model-specific typical efficiency is listed in the output table.
Remote Sense, Programming and Communication
| Remote sense |
Up to 0.5 V of load-wiring drop compensation. Connect +S pin 8 and -S pin 9 to the load using a twisted pair; for local operation connect each sense input to the corresponding output. |
| Remote ON/OFF |
Pin 7 to -S pin 9: short = ON; open = OFF. |
| Voltage programming |
90–110% of nominal voltage by external resistors. |
| Communication |
This C-suffix model includes I²C. SDA pin 17, SCL pin 18 and address pins 19/20/21 (A0/A1/A2) are enabled; follow the RCP-1000 communication manual. |
R1 connects +S pin 8 to V TRIM pin 13; R2 connects V TRIM pin 13 to -S pin 9. Use resistors rated at least 0.1 W; N.C. means no connection. Maintain the local sense-to-output links shown in the programming diagram.
For output levels 90/92/94/96/98/100% respectively, R1 values are 560 kΩ, 750 kΩ, 1 MΩ, 1.6 MΩ, 3.3 MΩ, N.C.. For output levels 100/102/104/106/108/110% respectively, R2 values are N.C., 330 kΩ, 130 kΩ, 62 kΩ, 30 kΩ, 10 kΩ.
Connector and Signal Assignments
CN501 is Positronic PCIB24W9M400A1; mating reference PCIB24W9F400A1. Pins 1/2/4: +V signal; 3/5/6: -V signal; 7: remote ON/OFF; 8: +S; 9: -S; 10: AC OK; 11: DC OK; 12: CS; 13: V TRIM; 14: T-Alarm; 15: 5V-AUX; 16: GND-AUX; 22: FG; 23: AC/L; 24: AC/N.
AC OK is low at 0–0.5 V when input is at least 82 V ±4 V, and high at 4.5–5.5 V below that threshold. DC OK is low when output is at least 80% ±5% of nominal and high below that threshold. T-Alarm is low within the safe thermal range and high above it. The detailed connector table references these status outputs to the non-isolated -V signal.
The auxiliary output is 4.3–5.3 V at 0.3 A maximum, referenced to GND-AUX pin 16, isolated from the main output and unaffected by remote ON/OFF. Connect CS pins between parallel units to enable current balance. AC OK and DC OK LEDs indicate normal input and output operation.
For this C version only: pins 17/18 are SDA/SCL; pins 19/20/21 are address A0/A1/A2. These communication assignments do not imply an interface in the blank-suffix model.
Mechanical Installation and Matching Equipment
| Body dimensions, L × W × H |
295 × 127 × 41 mm; 1U module profile. |
| Catalogue packing reference per unit |
1930 g (1.93 kg); not the carton mass. |
| Mechanical drawing |
Physical catalogue page 6; provide clearances for the handle, connector and mounting features beyond the listed body dimensions. |
| Matching shelf |
RCP-1UI / RCP-1UT; separately specified rack equipment. I specifies an AC-inlet shelf; T specifies a terminal-block shelf. |
The optional RCP-1U 19-inch shelf accepts three RCP-1000 modules. The catalogue describes approximately 3000 W per fully populated shelf and up to 8000 W across three shelves; actual available power depends on output voltage, populated modules and derating.
The module, rack shelf, control/monitor unit and mating connectors are separate configuration items unless expressly included in the ordered assembly. Use the exact connector reference and the model-specific pin assignment; a shared connector shell does not make different RCP families electrically interchangeable.
The mechanical drawing shows the fan/handle side opposite the electrical connector side; maintain the illustrated insertion, handle and ventilation clearance.

The catalogue lists a five-year warranty. Optional conformal coating is a separately specified configuration; it is not implied by the standard model code.
