MEAN WELL RCP-1600-12CAN is a rack-mount front-end AC/DC power supply module with a 12 V output rated at 125 A and 1500 W. It uses active PFC and a controlled DC fan, with remote sensing, voltage programming and hot-swap isolation for the matching rack system. This CAN version is a by-request communication configuration.

Model-Specific DC Output
| Rated output voltage |
12 V. |
| Rated output current |
125 A; load range 0–125 A. |
| Rated output power |
1500 W. |
| Ripple and noise, maximum |
150 mVp-p. |
| Built-in voltage adjustment |
11.5–15 V. |
| Voltage tolerance |
±1.0%; includes set-up, line and load regulation. |
| Line / load regulation |
±0.5% / ±0.5%. |
| Typical efficiency |
88.5% 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 250–370 VDC. |
| AC frequency |
47–63 Hz. |
| Typical AC input current |
14 A at 115 VAC; 8 A at 230 VAC. |
| Input power factor |
Built-in active PFC; typical PF 0.97 at 230 VAC and full load. |
| Cold-start inrush current |
35 A at 230 VAC. |
| Leakage current |
Less than 1.5 mA at 230 VAC. |
| Set-up / rise time |
1500 / 60 ms at 230 VAC, full load. |
| Typical hold-up time |
16 ms at 230 VAC and 75% load; 10 ms at 230 VAC and full load. |
Full rated output is available on the 180–264 VAC plateau; lower input voltages require derating.
Printed low-line limits for this voltage model: 115 VAC: 1200 W maximum and 100 A maximum; 100 VAC: 1050 W maximum and 87.5 A maximum; 90 VAC: 900 W maximum and 75 A maximum. Apply these together with the temperature curve.
The catalogue specifies withstand capability for a 300 VAC surge lasting 5 seconds; this is not a continuous input-voltage rating.
Protection and Cooling
| Short-circuit / overload protection |
105–115% of rated output current; constant-current limiting. If output remains below 80% of its set voltage for 5 seconds, output shuts down; re-power to recover. |
| Overvoltage protection |
15.75–18.75 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 FET supports hot-swap operation in the compatible rack system. |
Temperature and Environmental Limits
| Working temperature |
-30°C to 70°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 |
±0.03%/°C from 0°C to +50°C. |
| Vibration |
10–500 Hz, 2 G, 10-minute cycle; 60 minutes each along X, Y and Z. |
For horizontal installation, 100% load is shown from -30°C to +50°C at 230 VAC; the -30°C to below -25°C region is restricted to 230 VAC. Derate to 50% at +70°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 and Programmable Controls
| Remote sense |
Compensation up to 0.5 V. Route a twisted pair from +S pin 30 and -S pin 31 to the load. For local sensing, link +S to +V signal pin 28 and -S to -V signal pin 29. |
| Remote ON/OFF |
Short pin 17 to +5V-AUX pin 13 for ON; open for OFF. Control levels are referenced to GND-AUX pin 12, not to the positive auxiliary terminal. |
| Voltage programming range |
60–125% of nominal voltage; external PV at pin 27, referenced to -V signal pin 29. |
| Current programming range |
20–100% of rated current; external PC at pin 26, referenced to -V signal pin 29. |
| Communication protocol |
CANBus, ordered by request under the CAN suffix. |
PV is non-linear: the graph shows 100% output at 0–0.4 V control, the minimum output plateau at 0.4–1 V, then increasing output from 1 V to 4.7 V, and 125% output at 4.7–5 V. Follow the plotted curve for intermediate settings. Available output current is 100% up to nominal output voltage and falls to 80% when output voltage reaches 125%.
PC is non-linear: 20% current at 0.4–1 V control, increasing to 100% between 1 V and 4.7 V, and 100% at 4.7–5 V. Use the specified 20–100% programming range. The 0–0.4 V region is not an additional continuous rated-current allowance.
Use analog PV/PC only when not using PMBus or CANBus control. Use the built-in potentiometer only when neither bus control nor analog PV/PC is active. A programmed operating point must satisfy the voltage, current and total power limits.
With parallel supplies at light load, ripple may exceed the single-unit specification; the specified ripple level is restored above 5% output load. The address inputs and differential DA/DB lines are for the compatible rack current-sharing system.
Connector and Signal Assignments
CN1 is Positronic PCIM34W13M400A1; mating reference PCIM34W13F400A1. Pins 1/2/3/4/6 are -V and 5/7/8/9/10 are +V. Pins 11: +12V-AUX; 12: GND-AUX; 13: +5V-AUX; 14/15: CANL/CANH; 16: T-Alarm; 17: remote ON/OFF; 18: DC OK; 19: AC OK; 20/21/22/23: address A3/A2/A1/A0; 24: DB; 25: DA; 26: PC; 27: PV; 28: +V signal; 29: -V signal; 30: +S; 31: -S; 32: FG; 33: AC/L; 34: AC/N.
The 12 V auxiliary is 10.8–13.2 V at 0.8 A maximum; the 5 V auxiliary is 4.5–5.5 V at 0.3 A maximum. Both are referenced to isolated GND-AUX pin 12, include OR-ing isolation and remain available when remote control turns the main output off.
Remote ON accepts 4.5–5.5 V; open/OFF is -0.5 to +0.5 V, with 5.5 V maximum applied control voltage. DC OK is low (-0.5 to +0.5 V) above 80% ±5% output and high (3.5–5.5 V) below 77% ±5%. T-Alarm is low in normal operation and high for unsafe temperature or fan failure. AC OK has the opposite normal polarity: high at input ≥87 VAC and low at input ≤75 VAC. Status outputs source 10 mA maximum.
Communication, remote control and status signals use isolated GND-AUX pin 12. Address, DA/DB and analog PV/PC signals use non-isolated -V signal pin 29. The +V/-V signal pins are control references, not load-current terminals.
The LED is green in normal operation and red for overtemperature, overload or fan failure. Flashing red indicates an internal-temperature warning around 60°C while output remains on; this is not an ambient-temperature rating. PMBus can report the temperature warning on the PMBus version.
Mechanical Installation and Matching Equipment
| Body dimensions, L × W × H |
300 × 85 × 41 mm; 1U module profile. |
| Catalogue packing reference per unit |
1870 g (1.87 kg); not the carton mass. |
| Mechanical drawing |
Physical catalogue page 12; provide clearances for the handle, connector and mounting features beyond the listed body dimensions. |
| Matching shelf |
RHP-1UI-ACAN / RHP-1UT-ACAN; separately specified rack equipment. Select the CAN rack option for this CAN module. |
The RCP-1600 series is specified with power density up to 25 W/in³; this is a series maximum, not a guaranteed density for every voltage model. The optional RHP-1U 19-inch shelf accepts five RCP-1600 modules. The catalogue describes up to 8000 W per shelf and 24000 W across three shelves; a controller can monitor at most 15 supplies. The RKP-CMU1 control/monitor unit is separately available.
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.
For RCP-1600, the side drawing marks 2-M4 L5 mounting threads on each side; retain the illustrated connector and handle 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.
