产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total power (NMP1K2 model)

2 Wide input voltage range: 90~264VAC or 120~370VDC, frequency range 47~63Hz

3 High efficiency: Up to 91% (full load with H/K modules at nominal 24V/48V)

4 Compliance with multiple safety standards: ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, EN62368-1, IEC 60601-1 Ed3.1, IEC62368-1, EAC TP TC 004

5 Multiple protection functions: Overload (constant current limiting), overvoltage (shutdown, re-power to recover), overtemperature (shutdown, auto-recover after cooling)

6 Flexible control options: Global ON/OFF (RC1 pin) and local ON/OFF (RC2 pin for modules)

7 Remote sense capability to compensate for voltage drop on load wiring (up to 0.5V)

8 Current sharing function for parallel operation of NMS-240 modules

9 Signal outputs: DC OK (TTL level, indicates module output status), T-Alarm (TTL level for overtemperature)

10 Auxiliary power outputs: 5V/2A (NMP1K2 front-end), 5V/10mA (module Vcc2)

11 Voltage and current programming: PV pin for output voltage adjustment, PC pin for constant current level trimming (40~100% of rated current)

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple stable DC outputs

2 Test and measurement equipment needing flexible voltage/current configurations

3 Medical devices compliant with IEC 60601-1 safety standards

4 Communication systems and data centers for reliable power supply

5 Any application needing high power density and modular output flexibility

注意事项 PRECAUTIONS

1 Ensure the shorting connector (RC1 to GND-P) is installed; otherwise, the unit will not output power

2 For remote sense, use twisted pairs for +S/-S lines to reduce electromagnetic interference

3 Local ON/OFF control logic: Open RC2 (module pin3) to GND for ON, short for OFF

4 Parallel operation guidelines: Connect CS pins of all modules together; ensure output voltage difference between modules <0.2V; total power must not exceed 1200W; use short and large diameter wiring for parallel connections; remote control must turn all parallel modules ON/OFF simultaneously; do not use current programming (PC) function in parallel mode

5 Derating requirement: For output voltage <12V and ambient temperature between -15°C and -30°C, reduce output current to 90% of rated value

6 Mounting instructions: Use M4 screws for front-end mounting (torque 7~10 Kgf-cm); use M3.5 screws for module DC terminals (torque up to 10 Kgf-cm)

7 Overtemperature protection: The unit shuts down when overheated; it will recover automatically after cooling down

8 Leakage current: <400uA at 264VAC; touch current <100uA
