产品特点 FEATURES

1 Modular structure: NMP1K2 model offers 6 slots, supporting NMS-240 (single output) and NMD-240 (dual output) modules with voltage options including 5V/36A,12V/20A,24V/10A,48V/5A

2 Wide input voltage range: AC 90~264V or DC120~370VDC, suitable for global power grid applications

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

4 Dual safety compliance: Meets IEC60601-1 (medical standard with 2x MOPP isolation between primary and secondary) and IEC62368-1 (ITE standard)

5 Comprehensive protection mechanisms: Overload (constant current limiting), overvoltage (shutdown and recover on repower), overtemperature (auto-shutdown and recover after cooling)

6 Flexible control options: Global ON/OFF (via RC1 pin) and local module-level ON/OFF (via RC2/RC3 pins)

7 Real-time monitoring signals: DC OK (TTL level indicating output status), T-Alarm (overtemperature alarm signal)

8 Current sharing capability: Supports parallel operation of modules to increase output current (requires CS pin connection)

9 Auxiliary power supply: 5V/2A (NMP1K2) or 5V/1.5A (NMP650) for powering control circuits

10 Remote sense function: Compensates voltage drop on load wiring up to 0.5V

11 Voltage and current programming: PV pin for output voltage adjustment, PC pin for output current adjustment (available for NMS-240 modules)

12 Robust mechanical design: Specified mounting torque (12Kgf-cm for AC terminal,10Kgf-cm for DC output) and compatible with HRS DF11 series connectors

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound machines, blood analyzers), patient monitoring systems (complying with medical safety standards)

2 Industrial automation: PLC systems, motor drives, sensor networks requiring multiple stable voltage outputs

3 Test and measurement: Laboratory instruments, electronic component testing setups needing adjustable voltage and current

4 Communication systems: Base stations, network switches, routers requiring scalable modular power solutions

5 Data centers: Server racks, storage systems needing reliable and flexible power supplies

6 Research and development: Prototype testing environments with diverse power requirements

7 Industrial control panels: Equipment needing multiple isolated power outputs for different components

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding via FG terminal; use M4 screws for front-end mounting and M3.5 screws for DC output terminals, adhering to specified torque values (12Kgf-cm for AC terminal,10Kgf-cm for DC output)

2 Temperature derating: Follow derating guidelines—when output voltage <12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value; adjust load according to derating curves at high temperatures

3 Wiring: Use twisted pairs for remote sense lines to minimize interference; for parallel current sharing, use short and large-diameter wires to connect CS pins of modules

4 Control operation: If not using external global ON/OFF control, install the provided shorting connector (RC1 to GND-P); local module ON/OFF is achieved by opening (ON) or shorting (OFF) RC2/RC3 pins

5 Protection handling: When T-Alarm signal is high (overtemperature), stop operation and check ventilation; overvoltage/overload issues require repowering the device to recover

6 Parallel operation: Ensure output voltage difference between parallel modules is less than 0.2V; do not exceed the maximum total power (1200W for NMP1K2)

7 Connector compatibility: Use HRS DF11 series connectors for control and output terminals to avoid poor contact

8 Ventilation: Keep the air flow direction unobstructed to ensure effective heat dissipation
