产品特点 FEATURES

1 Modular design with 6 slots (NMP1K2 model) supporting up to 1200W total output power

2 Compatible with single-output (NMS-240) and dual-output (NMD-240) modules, each up to 240W

3 Wide input voltage range: 90~264VAC or 120~370VDC, suitable for global applications

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

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

6 Compliance with multiple safety standards: IEC60601-1 Ed3.1 (medical, 2x MOPP isolation), IEC62368-1 (ITE), etc.

7 Rich protection functions: Overload (constant current limiting), overvoltage (shut down & recover on re-power), overtemperature (automatic recovery after cooling)

8 Flexible control features: Global/local ON/OFF control, remote sense (compensate up to 0.5V voltage drop), output voltage/current programming (PV/PC pins)

9 Current sharing capability for parallel operation of NMS-240 modules to balance load distribution

10 DC OK signal (TTL level) to indicate output status; T-Alarm signal for overtemperature warning

11 Auxiliary power outputs: 5V/2A (front-end) and 5V/10mA (per module) for external control circuits

12 Compact mechanical design: 250×127×41mm (L×W×H) for easy integration into equipment cabinets

注意事项 PRECAUTIONS

1 Installation: Ensure proper airflow direction (as per mechanical specs) and use recommended mounting screws (M4) with torque 7~10 Kgf-cm; do not exceed maximum penetration depth

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

3 Wiring: Correctly connect remote control (RC pins) and sense lines (+S/-S) to avoid malfunction; use appropriate wire gauge for load and parallel connections

4 Parallel Operation: For NMS-240 modules, connect CS pins for current sharing; ensure output voltage difference between modules <0.2V; do not exceed total power (1200W for NMP1K2) or max slots (6)

5 Blank Slots: Use BLANK-NMS240 accessory for empty slots to maintain safety and airflow

6 Auxiliary Power: Do not exceed the current limits of auxiliary outputs (5V/2A front-end,5V/10mA per module)

7 Remote Sense: Ensure sense lines are connected correctly to compensate for voltage drop on load wiring (max 0.5V)

8 Safety: Do not operate beyond specified electrical or environmental parameters; disconnect power before maintenance

9 Overtemperature: Monitor T-Alarm signal to prevent overheating; ensure adequate ventilation in the installation environment

10 Programming: Follow guidelines for PV (voltage) and PC (current) programming to avoid incorrect output settings
