产品特点 FEATURES

1 Modular design: NMP1K2 model has 6 slots for output modules (NMS-240 single output or NMD-240 dual output), each module up to 240W, total max power 1200W

2 Wide input range: AC 90-264V or DC120-370V, frequency 47-63Hz, suitable for global applications

3 High efficiency & power factor: PF>0.95@230VAC full load; typical efficiency up to 91% (for H/K modules at 24V/48V nominal voltage)

4 Safety compliance: Meets medical (2x MOPP isolation between primary and secondary) and ITE standards (e.g., EN60601-1 Ed.3.1, UL62368-1, IEC60950-1)

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down and re-power to recover), overtemperature (auto-recover after cooling), short circuit (hiccup mode or constant current for specific modules)

6 Flexible control: Global ON/OFF (via RC1 pin) and local module ON/OFF (via RC2/RC3 pins); remote sense (compensate up to 0.5V wiring drop); voltage programming (PV pin) and current programming (PC pin); DC OK signal (TTL level for output status); current sharing (for parallel module operation)

7 Auxiliary power: +5V-AUX_P (2A output for NMP1K2) and Vcc2 (5V/10mA per module)

8 Wide operating temperature: -30°C to +70°C (with derating as per specification)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control panels

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

3 Telecommunications: Supporting routers, switches, base stations, and communication systems

4 Test & measurement: Providing stable, adjustable power for lab testing and electronic device debugging

5 Data centers: Supplying power to server racks, storage systems, and network equipment with flexible voltage configurations

6 Embedded systems: Custom power solutions for embedded devices requiring multiple output voltages

注意事项 PRECAUTIONS

1 Installation: Use M4 screws with 7-10 Kgf-cm torque for front-end mounting; M3.5 screws with max 10 Kgf-cm torque for output terminals; ensure correct screw penetration depth to avoid damage

2 Derating: Follow derating guidelines—e.g., when output voltage <12V and ambient temp is -15°C to -30°C, derate current to 90% of rated value; reduce output power at higher ambient temperatures

3 Control setup: For global ON/OFF, assemble the shorting connector (RC1 to GND-P) if not using external control; for local module control, set RC2/RC3 pins correctly (open = ON, short = OFF)

4 Parallel operation: When paralleling modules for current sharing, connect CS pins together; ensure output voltage difference between modules <0.2V; total power must not exceed 1200W; use short, large-diameter wires; avoid using PC (current programming) function in parallel mode

5 Wiring: Use appropriate wire gauge to minimize voltage drop; for remote sense, connect +S/-S pins directly to load terminals

6 Protection handling: If overvoltage/overtemperature occurs, power off the device, check for issues, and re-power only after resolving the problem

7 Environment: Avoid operating in humid, dusty, or corrosive environments; ensure proper airflow as per mechanical specifications
