产品特点 FEATURES

1 Modular power supply design with NMP1K2 front-end (1200W max, 6 slots) supporting single-output (NMS-240) or dual-output (NMD-240) modules

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

3 Complies with multiple safety standards including medical (ANSI/AAMI ES60601-1 Ed3.1) and ITE (UL62368-1) specifications

4 Supports global/local ON/OFF control for flexible power management

5 Functions like remote sense (compensate up to 0.5V wiring drop), output voltage/current programming, DC OK signal (output status indication), and T-Alarm (overtemperature alert)

6 Current sharing capability for parallel operation of modules to balance load

7 Built-in protections: overload (constant current limiting), overvoltage (shutdown & repower recover), overtemperature (shutdown & auto-recover)

8 Isolation levels: Primary-Secondary (2x MOPP), Primary-Earth (1x MOPP); Withstand voltage: I/P-O/P (4KVAC), I/P-FG (2KVAC), O/P-FG (0.5KVAC)

9 Compact dimensions: Front-end (250*127*41mm), modules (118.5*37.9*18mm)

10 Auxiliary power outputs: 5V-AUX-P (2A for NMP1K2), Vcc2 (5V/10mA for modules)

11 Wide working temperature range: -30~+70℃ (with derating as per guidelines)

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple adjustable DC power outputs

2 Medical devices compliant with ES60601-1 safety standards

3 Test and measurement equipment needing flexible voltage/current configurations

4 Communication base stations and network devices

5 Laboratory setups for prototype testing with variable power requirements

6 Industrial control panels and embedded systems

7 Equipment requiring parallel power modules for higher current capacity

注意事项 PRECAUTIONS

1 Derating requirements: When ambient temperature exceeds 50℃, reduce output load as per derating curve; for output voltage <12V and temp between -15~-30℃, derate output current to 90% of rated value

2 Installation: Use recommended screw sizes (M4 for front-end, M3.5 for modules) and mounting torque (12Kgf-cm for front-end AC terminal,10Kgf-cm for module DC terminal)

3 Parallel operation: Max 6 NMS-240 modules for NMP1K2; connect CS pins for current balance; ensure output voltage difference between modules <0.2V; total power not exceed 1200W

4 Global ON/OFF control: Must assemble the shorting connector (RC1 to GND-P) that comes with the PSU to enable output

5 Remote sense: Use twisted pairs for sense lines to minimize interference

6 Blank slots: Install BLANK-NMS240 accessory in unused slots

7 Wiring: Use short, large-diameter wires for parallel connections to reduce voltage drop

8 Overload protection: For C (5V) or E (12V) modules in parallel, short protection is hiccup mode or constant current limiting
