产品特点 FEATURES

1 Modular power supply with 6 slots, supporting up to 1200W total output power

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

3 High power factor: PF>0.95 at 230VAC full load, PF>0.98 at 115VAC full load

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

5 Compliance with multiple safety standards: ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 Ed.3.1, EN62368-1, IEC 60601-1 Ed.3.1, IEC62368-1, IEC60950-1, EAC TP TC004

6 Rich protection functions: Over temperature (shuts down output, recovers automatically when cooled), over voltage (shuts down output, requires re-power to recover), overload (constant current limiting)

7 Flexible control features: Global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (TTL level indicating module status), current sharing (CS pin for parallel module operation)

8 Auxiliary power outputs: +5V-AUX-P (2A for NMP1K2) for system use, Vcc2 (5V/10mA) for module control

9 Compact mechanical design with specified mounting dimensions and torque requirements

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, DCS, servo drives, and other control equipment

2 Medical devices: Compatible with medical standards, suitable for diagnostic instruments, patient monitoring systems (note: ensure compliance with specific device requirements)

3 Telecommunications infrastructure: Base stations, network routers, switches, and communication cabinets

4 Data centers and server rooms: Providing stable power to server racks, storage systems, and network equipment

5 Test and measurement instruments: Supporting precision testing equipment that requires multiple DC outputs

6 LED lighting systems: High-power LED arrays and lighting control systems

7 Any application requiring modular, flexible, and reliable DC power with multiple output configurations

注意事项 PRECAUTIONS

1 Ensure the shorting connector (from RC1 pin6 to GND-P pin3 of CN32) is installed if global ON/OFF control is not used; otherwise, the power supply will have no output

2 For parallel module operation: Connect CS pins of all modules together to enable current balance; ensure output voltage difference between parallel modules is less than 0.2V; total output current should not exceed (rated current per module × number of modules) and total power ≤1200W; maximum 6 modules can be paralleled for NMP1K2; use short, large-diameter wiring for parallel connections; remote control must turn ON/OFF all parallel modules simultaneously; PC (current programming) function should not be used in parallel mode

3 Temperature derating: When output voltage is below12V and ambient temperature is between -15°C and -30°C, reduce output current to90% of rated current

4 Remote sense lines should be twisted in pairs to minimize noise interference

5 Follow specified mounting torque:12Kgf-cm for AC input terminals,10Kgf-cm for DC output terminals; use recommended screw sizes (M4 for mounting, M3.5 for DC output)

6 Do not exceed 240W maximum load per NMS-240 module

7 For local ON/OFF control: Open RC2 pin (module) to GND for ON, short for OFF

8 Ensure proper grounding to comply with leakage current requirements (earth leakage <400uA at264VAC, touch current <100uA at264VAC)
