产品特点 FEATURES

1 Modular design: 6-slot 1200W front-end (NMP1K2) compatible with single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240:30V/5A×2) modules, flexible configuration via code (00-31)

2 Wide input range: AC 90-264V or DC120-370V, frequency 47-63Hz, high power factor (>0.95@230VAC full load)

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

4 Safety compliance: Meets medical (2x MOPP between primary-secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, etc.)

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down & recover on repower), overtemperature (auto-recover after cooling), inrush current limiting, leakage current <400uA@264VAC

6 Rich control functions: Global/local ON/OFF control, remote sense (compensate up to 0.5V voltage drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), current sharing (parallel operation support)

7 Auxiliary power: 5V/2A front-end auxiliary output, 5V/10mA per module auxiliary output

8 Mechanical specs: Chassis size 250×127×41mm, mounting torque 7-10Kgf-cm for M4 screws

使用场景 APPLICATIONS

1 Industrial automation systems: Power supply for PLCs, sensors, actuators, and control panels requiring multiple voltage outputs

2 Medical equipment: Compatible with medical devices (thanks to 2x MOPP isolation) like diagnostic instruments, patient monitors, and laboratory equipment

3 Test & measurement setups: Flexible voltage/current configurations for testing electronic components and devices

4 Telecommunication infrastructure: Power for routers, switches, and communication modules in telecom rooms or base stations

5 Data center applications: Modular power for server racks, storage systems, and network equipment needing reliable and scalable power

6 Custom electronic systems: R&D projects or custom devices requiring adjustable voltages and multiple output channels

注意事项 PRECAUTIONS

1 Installation: Ensure proper mounting torque (M4 screws:7-10Kgf-cm, M3.5 for output terminals:10Kgf-cm), follow air flow direction for heat dissipation

2 Derating guidelines: When ambient temp is -15℃ to -30℃ and output voltage <12V, derate output current to 90% of rated value; refer to derating curves for temp and input voltage variations

3 Remote sense usage: Connect +S/-S pins to load terminals to compensate for wiring voltage drop (max 0.5V)

4 Parallel operation: For current sharing, connect CS pins of modules, ensure output voltage difference <0.2V among parallel modules; total power not exceed 1200W; max 6 modules in parallel for NMP1K2

5 ON/OFF control: Use shorting connector for RC1-GND-P to enable output if global ON/OFF is not used; local control via RC2/RC3 pins (open=ON, short=OFF)

6 Blank slot requirement: If slots are unused, install BLANK-NMS240 module to maintain proper heat dissipation and safety

7 Maintenance: Regularly check for loose connections, dust accumulation (clean with dry air), and ensure operating environment meets temp (-30℃ to +70℃) and humidity (20-90% RH non-condensing) specs
