产品特点 FEATURES

1 Modular design: 6-slot front-end (NMP1K2) supporting up to 1200W total power, compatible with single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240: dual 30V/5A) modules

2 Flexible control options: Global ON/OFF (via RC1 pin) and local ON/OFF (per module via RC2/RC3 pins) for precise power management

3 Advanced monitoring & programming: Remote sense (compensates wiring voltage drop up to 0.5V), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (indicates module output status), T-Alarm (over-temperature warning)

4 Parallel operation support: Current sharing (CS pin) for parallel modules to balance load, up to 6 modules in parallel (NMP1K2) with total power ≤1200W

5 Comprehensive protection: Over-voltage (OVP), over-current (OCP), over-temperature (OTP), over-load (OLP) protections; OVP/OTP trigger shutdown (re-power to recover), OCP uses constant current limiting

6 Wide input range & high efficiency: AC input 90-264VAC, DC input120-370VDC; high efficiency (up to91% for H/K modules at24V/48V nominal voltage)

7 Safety compliance: Meets international safety standards like IEC60601-1, UL62368-1, EN60601-1 Ed.3.1 (medical 2x MOPP isolation), suitable for medical and industrial applications

使用场景 APPLICATIONS

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

2 Medical equipment: Compatible with medical devices (due to2x MOPP isolation) like diagnostic instruments, patient monitoring systems, and laboratory equipment

3 Telecommunications: Supporting telecom base stations, network switches, and routers that need stable multi-voltage power

4 Test & measurement: Powering electronic test equipment (oscilloscopes, signal generators) that requires precise voltage/current control

5 Data centers: Providing modular power to server racks, storage systems, and network infrastructure with flexible scaling

6 Renewable energy systems: Adapting to wide DC input (120-370VDC) for solar or wind power conversion systems needing multiple output voltages

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding (FG pin) to avoid electrical hazards; use recommended screw sizes (M4 for front-end, M3.5 for modules) with specified torque (12Kgf-cm for front-end AC terminal,10Kgf-cm for module DC terminal)

2 Global ON/OFF operation: For NMP1K2, the shorting connector (RC1 to GND-P) must be assembled; otherwise, no output is provided

3 Local ON/OFF operation: For NMS-240 modules, open RC2-GND to turn on, short to turn off; for NMD-240, open RC2-GND1 (V1) or RC3-GND2 (V2) to turn on

4 Parallel operation: Ensure output voltage difference between parallel modules <0.2V; use short, large-diameter wiring; total load ≤100% of combined rated current; avoid using PC function in parallel mode

5 Derating requirements: For output voltages <12V and ambient temp between -15℃ to -30℃, derate output current to90% of rated value; follow derating curves for high ambient temps (e.g., at70℃, load derated to~50% for230VAC)

6 Protection recovery: In case of OVP/OTP shutdown, re-power the unit to recover; OCP triggers constant current limiting (no shutdown)

7 Maintenance & environment: Keep the unit clean and free of dust for heat dissipation; avoid operating in humid or corrosive environments (20-90% RH non-condensing)

8 Wiring for remote sense: Connect +S/-S pins to load terminals to compensate voltage drop; use20-26AWG wires for module DC terminals with10mm strip length
