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

3 Compliance with multiple safety standards: Medical (2x MOPP between primary and secondary), ITE (UL62368-1, EN62368-1, etc.)

4 High efficiency (up to 91% typical for full load with H/K modules at 24V/48V), power factor >0.95 at 230VAC full load

5 Flexible output modules: Supports single-output (NMS-240) and dual-output (NMD-240) modules with voltages like 5V,12V,24V,48V, adjustable voltage ranges

6 Remote control and monitoring features: Global/local ON/OFF control, DC OK signal (TTL level for output status), T-alarm signal (overtemperature warning), remote sense (compensate voltage drop up to 0.5V)

7 Programmable functions: Output voltage programming (PV pin), constant current level programming (PC pin)

8 Current sharing capability for parallel operation of modules, ensuring balanced load distribution

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

10 Built-in protection mechanisms: Overvoltage (shut down, re-power to recover), overcurrent (constant current limiting), overtemperature (auto-recover after cooling)

11 Mechanical specs: Dimensions 250×127×41mm (L×W×H), mounting with M4 screws (torque 7~10 Kgf-cm)

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, sensors, actuators with varying DC voltage needs

2 Medical equipment: Compatible with devices requiring safe, isolated power (meets medical safety standards)

3 Test and measurement setups: Flexible power supply for electronic component testing with adjustable voltages/currents

4 Telecommunication equipment: Powering routers, switches, and communication modules with multiple DC outputs

5 Data center infrastructure: Modular power for server racks or network devices needing remote monitoring

6 Laboratory research: Customizable DC power for experimental setups with programming and monitoring requirements

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector (RC1 to GND-P) is assembled to enable output; otherwise, no power output will be present

2 Derating guidelines: When output voltage is below 12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value; follow derating curves for temperature and input voltage variations

3 Parallel operation: Connect CS pins of modules for current sharing; max 6 modules in parallel (NMP1K2); ensure output voltage difference between modules is <0.2V; total output power must not exceed 1200W

4 Remote sense: Use +S/-S pins to compensate for voltage drop on load wiring (up to 0.5V)

5 Programming limits: PV pin (voltage programming) and PC pin (current programming) must be used within specified ranges to avoid damage

6 Safety precautions: Proper grounding is mandatory; avoid overloading modules beyond their rated power; monitor T-alarm signal for overtemperature conditions

7 Protection recovery: Overvoltage/overcurrent protection triggers will shut down the output; re-power to recover; overtemperature protection auto-recovers once cooled

8 Maintenance: Regularly check for loose connections; keep the device in a well-ventilated area to prevent overheating
