MEAN WELL RST-10000-36 is a single-output, fan-cooled AC/DC power supply with a 36 V nominal output, 276 A rated current and 9936 W rated output. It supports the specified three-phase delta or Y input connections, active PFC, programmable voltage and current, remote sensing and active current sharing. Input wiring, temperature derating and control-mode limits must be applied together; the family name is not an unconditional output-power rating.

Model and Output Specifications
| Complete model |
RST-10000-36 |
| Nominal voltage / current range / rated power |
36 V DC / 0–276 A / 9936 W |
| Ripple and noise, maximum |
200 mVp-p |
| Built-in potentiometer adjustment |
35–43.2 V |
| Tolerance / regulation |
Voltage tolerance ±1.0%; line regulation ±0.5%; load regulation ±0.5% |
| Typical efficiency |
90% |
Unless otherwise specified, measurements use 230 VAC delta or 400 VAC Y input, rated load and 25°C ambient. Voltage tolerance includes setup tolerance and line/load regulation. Ripple is measured with 20 MHz bandwidth using a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors.
The separate efficiency-versus-load graph applies only to the 48 V model at 230 VAC delta and 400 VAC Y. It is not a replacement for the model-specific typical efficiency above.
Three-Phase Input and Wiring
| Delta connection |
Three-phase, three-wire: 196–305 VAC line-to-line |
| Y connection |
Three-phase, four-wire: 340–530 VAC line-to-line, with the illustrated 196–305 VAC phase-to-neutral supply and neutral connection |
| Frequency / active PFC |
47–63 Hz; typical power factor 0.95 at 230 VAC delta or 400 VAC Y, full load |
| Typical input current / inrush |
30 A / 150 A at 230 VAC delta; 18 A / 100 A at 400 VAC Y |
| Leakage current |
<7 mA at 305 VAC delta or 530 VAC Y |
Follow the exact AC connection drawings on PDF page 14. In delta, connect phase R to L1 and N3, phase S to L2 and N1, and phase T to L3 and N2. In Y, connect R/S/T to L1/L2/L3 respectively and connect neutral to N1/N2/N3. Connect FG to protective earth in either arrangement. The delta and Y terminal links are different; do not interchange them.
TB1 pin assignment is 1=L1, 2=N1, 3=L2, 4=N2, 5=L3 and 6=N3. Maximum AC-terminal mounting torque is 18 kgf·cm. These are three-phase AC configurations; the catalogue does not establish a single-phase or DC-input rating.
Timing, Cooling and Derating
| Setup / rise time |
2200 ms / 80 ms at full load |
| Typical hold-up time |
20 ms at 230 VAC and 75% load; 14 ms at 230 VAC and full load |
| Ambient operating range |
−30 to +70°C, subject to the horizontal-installation derating curve |
| Thermal load limit |
100% load from −30 through +50°C ambient; derate to 50% at +70°C |
Cooling uses built-in DC fans with fan-speed control. Keep the illustrated fan-end airflow path unobstructed. The 60 Hz static-input graph permits 100% load across the specified delta 196–305 VAC or Y 340–530 VAC range; it does not remove thermal, wiring or output-rating limits.
For operation above 2000 m, the stated ambient-temperature derating for this fan-cooled design is 5°C per additional 1000 m. No separate maximum installation altitude is inferred from this derating note. The block diagram lists PFC switching at 70 kHz and PWM switching at 67 kHz.
Voltage and Current Programming
| DIP-SW position 3 |
OFF: built-in SVR adjustment; ON: external voltage programming (PV) |
| External PV |
20–120% of nominal output voltage; CN992 or CN993 pin 6 PV+ and pin 4 PV− |
| DIP-SW position 2 |
OFF: default overload/current setting; ON: external constant-current programming (PC) |
| External PC |
20–100% of rated current; CN992 or CN993 pin 9 PC+ and pin 7 PC− |
The PV graph marks 1 V external control at 20% nominal output, 5 V at 100% and 6 V at 120%. The PC graph marks 1 V at 20% rated current and 5 V at 100%. Both graphs are labelled nonlinear; follow those curves rather than assuming a precision linear conversion outside the illustrated points.
The PV application drawing retains the factory local-sense connections: +S to +V and −S to −V. The independent remote-sense installation is described separately. Programmed voltage/current ranges do not authorize exceeding the applicable output-power, temperature or protection limits.
Reducing PV from a high level to a lower level at light or no load can trigger floating overvoltage protection. The catalogue recommends switching the supply off, setting PV to the lowest level and then adjusting output to the desired value.
Protection and Selectable OLP Mode
| Overload threshold |
100–112% of rated output power |
| DIP-SW position 1 OFF |
Continuous constant-current mode during overload when output voltage is greater than 50% of rated output voltage |
| DIP-SW position 1 ON |
Constant-current limiting followed by shutdown after 5 seconds under overload or short circuit; re-power to recover |
| Overvoltage |
45–50.4 V; output shutdown, re-power to recover |
| Overtemperature |
Output shutdown; automatic recovery after temperature falls |
Continuous current limiting is conditional on output voltage remaining above 50% of rated voltage; it is not an unrestricted short-circuit operating mode. Short circuit, overload, overvoltage, overtemperature and fan failure are listed protection/alarm features. The fan-failure signal is detailed below without inventing an additional recovery sequence.
Remote Sense and Remote ON/OFF
| Remote-sense compensation |
Up to 0.3 V of load-wiring voltage drop |
| Sense pins |
CN992/CN993 pin 3 = +S; pin 5 = −S |
| Remote-control pins |
CN992/CN993 pin 10 = RC+; pin 8 = RC−; CN991 pin 1 = 12V-AUX and pin 3 = GND-AUX |
For remote sensing, connect +S and −S to the corresponding load terminals and twist the sense pair to reduce noise pickup. When remote sense is not used, connect +S to the local +V output and −S to the local −V output; these local links are the factory default.
Connect RC− to GND-AUX and place the control switch between RC+ and 12V-AUX as drawn. Closing the switch turns the main output ON; opening it turns the main output OFF. CN991 pin 1 provides 11.4–12.6 V, maximum 0.1 A, referenced to pin 3, and is not switched by remote OFF. This auxiliary output is specified only for remote ON/OFF control, not as a general-purpose auxiliary power supply.
Two-Unit Current Sharing
| Maximum parallel configuration |
Two units, corresponding to the family 1+1 configuration |
| Maximum total current |
Rated current per unit × number of units × 0.9 |
| Voltage matching |
Set the difference between output voltages to less than 0.2 V |
Connect +S, −S, CS+, CS−, RC+ and RC− mutually in parallel as shown on PDF page 18. When using remote sense in parallel, connect the load-sensing wire only to the master unit. Keep remote-sense wiring at least 30 cm from input wiring.
Current sharing may not be fully balanced below 5% of the aggregate rated current. The family headline of up to 20000 W does not override the actual per-model power, two-unit limit, ×0.9 current formula or thermal derating. Do not use the four-unit statement from other RST models for RST-10000.
CN992 and CN993 Control Connections
| Connector / mating housing |
HRS DF11-10DP-2DS / HRS DF11-10DS, or equivalent |
| Pins 1–5 |
1 CS−; 2 CS+; 3 +S; 4 PV−; 5 −S |
| Pins 6–10 |
6 PV+; 7 PC−; 8 RC−; 9 PC+; 10 RC+ |
CN992 and CN993 are internally connected. The contact designation is printed as HRS DF11-**SC or equivalent; the wildcard is not a complete order code. Select the actual contact variant and wire compatibility from the connector manufacturer rather than guessing the missing characters. Mating housings and contacts are identified as interface references, without an unsupported supplied-quantity or accessory-kit claim.
CN991 Auxiliary and Alarm Pinout
| Connector / mating housing |
HRS DF11-20DP-2DS / HRS DF11-20DS, or equivalent; contact designation HRS DF11-**SC or equivalent |
| Auxiliary / local-voltage signals |
Pin 1 12V-AUX; pin 3 GND-AUX; pin 5 +V(signal) and pin 7 −V(signal) are for local sense only and must not connect directly to the load |
| DC-OK open collector |
Pin 4 DC-OK2, pin 2 DC-OK2-GND; low when the power supply turns on |
| AC-fail open collector |
Pin 8 AC-FAIL2, pin 6 AC-FAIL2-GND; low when input voltage is too low |
| OTP / fan-fail open collectors |
Pin 9 OTP2 with pin 11 return: low on overtemperature protection. Pin 10 FAN-FAIL2 with pin 12 return: low when the internal fan fails |
| OTP / DC-OK relay contacts |
Pins 13/15 OTP1/OTP1-GND close on overtemperature protection. Pins 14/16 DC-OK1/DC-OK1-GND close when the power supply turns on |
| AC-fail / fan-fail relay contacts |
Pins 19/17 AC-FAIL1/AC-FAIL1-GND close when input voltage is too low. Pins 20/18 FAN-FAIL1/FAN-FAIL1-GND close when the internal fan fails |
The relay contacts are normally open, rated at a maximum 30 V / 1 A resistive. DC-OK closes for normal power-on status; the other contacts close for their stated fault. Do not interpret all four signals as having the same fault-active meaning.
Open-collector outputs require an external voltage source, are isolated from the main output, and support a maximum 10 mA sink current and 20 V external voltage. The circuitry includes a 24 V zener; this does not raise the 20 V external-input limit. The application diagram shows four 10 kΩ pull-up resistors as circuit examples, not supplied accessory items. GND-AUX is isolated from the main +V/−V terminals.
Green LED1 lights when output voltage is OK; red LED2 lights when protection occurs.
