产品特点 FEATURES

1 Modular design: NMP1K2 model offers 6 slots for flexible configuration, supporting single-output (NMS-240) and dual-output (NMD-240) modules each up to 240W.

2 Wide input range: Accepts 90-264VAC or 120-370VDC, suitable for global applications.

3 High efficiency: Up to 91% efficiency at full load (with H/K modules at 24V/48V nominal voltage), reducing energy loss.

4 Multiple protection functions: Includes overload (constant current limiting or hiccup mode), overvoltage (shut down, re-power to recover), overtemperature (auto-recover when cool), and short circuit protection.

5 Compliance with safety standards: Meets medical (ANSI/AAMI ES60601-1 Ed.3.1, 2x MOPP isolation) and ITE (UL62368-1, EN62368-1) standards, suitable for medical and industrial use cases.

6 Flexible control options: Supports global (RC1 pin) and local (RC2/RC3 pins) ON/OFF control; remote sense function compensates up to 0.5V voltage drop on load wiring.

7 Advanced features: Current sharing for parallel operation (max 6 modules for NMP1K2), DC OK signal (TTL level indicating output status), auxiliary power outputs (5V/2A for front-end,5V/10mA for modules), and voltage/current programming (PV/PC pins for adjusting output voltage/current).

8 EMC compliance: Conforms to EN55032 (emission), EN61000 series (immunity) standards, ensuring minimal interference with other devices.

9 Mechanical specs: NMP1K2 front-end size is 250x127x41mm (LxWxH), weight ~2kg; modules are 118.5x37.9x18mm, easy to install and maintain.

使用场景 APPLICATIONS

1 Medical equipment: Suitable for diagnostic devices (like ultrasound machines), patient monitors, and laboratory equipment due to medical safety compliance (2x MOPP isolation).

2 Industrial automation: Ideal for PLC systems, control panels, and industrial sensors requiring multiple stable DC voltage outputs.

3 Test and measurement: Used in lab setups where custom voltage/current configurations are needed (via PV/PC programming functions).

4 Communication systems: Power supply for routers, switches, and base stations, leveraging wide input range and reliable protection.

5 Data centers: Supporting server racks with flexible power distribution via modular slots and parallel operation for higher power needs.

6 Custom electronic systems: Any application requiring multiple, adjustable DC outputs with high reliability and safety standards.

注意事项 PRECAUTIONS

1 Installation precautions: Use recommended screws (M4 for front-end mounting, M3.5 for module DC terminals) with specified torque (12Kgf-cm for front-end AC terminal,10Kgf-cm for module DC terminal) to ensure secure connections.

2 Operating conditions: Follow derating guidelines—e.g., when output voltage <12V and ambient temp is -15 to -30°C, derate output current to 90%; reduce load at high temps as per derating curves.

3 Global ON/OFF setup: If not using global ON/OFF control, install the shorting connector (RC1 to GND-P) to enable output; otherwise, the power supply will have no output.

4 Parallel operation: For current sharing, connect CS pins of all parallel modules; ensure output voltage difference between modules is <0.2V; total power must not exceed 1200W for NMP1K2; do not use the PC (current programming) function when modules are in parallel.

5 Remote sense usage: Use twisted pairs for sense lines (+S/-S) to minimize noise interference; the function compensates up to 0.5V voltage drop on load wiring.

6 Protection recovery: Overload/overvoltage protection requires re-powering the device to recover; overtemperature protection automatically recovers once the internal temperature drops below the threshold.

7 Wiring guidelines: Use appropriate wire gauge for DC outputs to reduce voltage drop; for parallel modules, use short, large-diameter wires to ensure current balance.

8 Environmental requirements: Operate in non-condensing humidity (20-90% RH) and avoid dusty/corrosive environments; store at -40 to +85°C when not in use.
