产品特点 FEATURES

1 Modular design with 6 slots for flexible configuration (supports NMS-240 single output modules and NMD-240 dual output modules)

2 High total power capacity of up to 1200W to meet diverse power demands

3 Wide input voltage range: 90~264VAC or 120~370VDC, compatible with global power grids

4 Compliance with medical (2x MOPP between primary and secondary) and ITE safety standards, suitable for medical and industrial applications

5 High power factor: >0.95 at 230VAC full load, >0.98 at 115VAC full load, reducing grid impact

6 High efficiency up to 91% (typical) at full load with H/K modules (24V/48V nominal), saving energy

7 Multiple protection functions: Overload (constant current limiting or shut down), overvoltage (shut down, re-power to recover), overtemperature (shut down, auto-recover after cooling)

8 Support for global and local ON/OFF control: Global control via RC1 pin, local control via module RC2/RC3 pins

9 Auxiliary power outputs: 5V@2A (front-end) and 5V@10mA (modules) for external circuit use

10 DC OK signal (TTL level) to indicate module output status, facilitating system monitoring

11 Current sharing capability for parallel operation of NMS-240 modules, ensuring balanced load distribution

12 Remote sense function to compensate for voltage drop on load wiring (up to 0.5V)

13 Output voltage and current programming via PV/PC pins for customized settings

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices, patient monitoring systems, laboratory instruments (due to medical safety compliance)

2 Industrial automation: PLC systems, motor drives, control panels, robotics (modular design adapts to varying power needs)

3 Test and measurement: Electronic test benches, signal generators, oscilloscopes (stable output and flexible configuration)

4 Communication systems: Base stations, network switches, routers (reliable power supply with wide input range)

5 Data centers: Server racks, storage systems (high power capacity and modular scalability)

6 Research and development: Prototype testing, custom electronic systems (programmable output for diverse test conditions)

7 Industrial IoT devices: Edge computing nodes, sensor networks (stable power with remote monitoring features)

注意事项 PRECAUTIONS

1 Installation: Ensure proper mounting torque (7~10 Kgf-cm for M4 screws), maintain correct airflow direction (as per mechanical specification) for heat dissipation

2 Derating guidelines:

3 When ambient temperature exceeds 50℃, derate output current according to the derating curve

4 For output voltage below 12V and ambient temperature between -15℃ to -30℃, derate output current to 90% of rated value

5 Parallel operation:

6 Connect CS pins of all modules to enable current sharing; output voltage difference between modules should be less than 0.2V

7 Total output power should not exceed 1200W; maximum 6 modules in parallel (NMP1K2)

8 Do not use output current programming (PC) function when modules are in parallel

9 Use short and large-diameter wiring for parallel connections to minimize voltage drop

10 Global ON/OFF control: The shorting connector (RC1 to GND-P) must be assembled to enable global output; otherwise, the unit will have no output

11 Remote sense: Connect +S/-S pins to load terminals to compensate for voltage drop on wiring (up to 0.5V)

12 Overvoltage protection: In case of overvoltage, the power supply will shut down; re-power on to recover

13 Overtemperature protection: If internal temperature exceeds the limit, the power supply will shut down and auto-recover once cooled down

14 Wiring: Use appropriate wire sizes (20~26AWG for control pins) and ensure correct pin assignments to avoid damage
