产品特点 FEATURES

1 Modular design: Supports up to 6 slots for output modules (NMP1K2 model), allowing flexible configuration of multiple output voltages (5V,12V,24V,48V etc.) via single (NMS-240) or dual (NMD-240) output modules

2 High power capacity: Maximum total output power of 1200W for NMP1K2, suitable for high-demand applications

3 Compliance with safety standards: Meets medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1 etc.), ensuring safe use in medical and industrial environments

4 Rich protection functions: Equipped with overvoltage protection (O.V.P), overcurrent protection (O.C.P), overtemperature protection (O.T.P), overload protection (O.L.P) to safeguard the power supply and connected devices

5 Remote monitoring and control: Supports remote sense (compensates voltage drop up to 0.5V), DC OK signal (TTL level indicating output status), T-Alarm (overtemperature alarm signal), and remote ON/OFF control (global or local)

6 Current sharing capability: Allows parallel operation of multiple NMS-240 modules to achieve higher current output, with current balance ensured via CS pin connection

7 Auxiliary power outputs: Provides +5V-AUX-P (2A for NMP1K2) and Vcc2 (5V/10mA for output modules) to power external control circuits

8 Derating support: Adapts to different operating conditions with derating curves for ambient temperature and input voltage, ensuring stable performance under harsh environments

使用场景 APPLICATIONS

1 Medical equipment: Suitable for medical devices requiring compliant power supplies (e.g., diagnostic instruments, patient monitoring systems) due to its medical safety standards

2 Industrial automation: Used in PLC systems, industrial control panels, and robotic equipment that need multiple stable voltage outputs

3 Test and measurement: Ideal for lab instruments (oscilloscopes, signal generators) that require precise and adjustable power inputs

4 Communication systems: Powers base stations, routers, and network devices with multiple voltage requirements

5 Data centers: Supports server racks and storage systems needing high-power modular power solutions

6 Embedded systems: Used in custom embedded devices requiring flexible voltage configurations and reliable performance

7 Parallel operation applications: Applied in scenarios needing higher current output (e.g., heavy-duty industrial machinery) by paralleling multiple modules

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector is assembled if the global ON/OFF control function is not used to enable output

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 to avoid overheating

3 Remote sense usage: Twist the +S and -S sense lines in pairs to minimize interference when using remote sense function

4 Parallel operation rules: When paralleling NMS-240 modules, connect CS pins mutually; ensure output voltage difference between modules is less than 0.2V; total output power should not exceed 1200W for NMP1K2; do not use the PC (output current programming) function in parallel mode

5 ON/OFF control: Understand the logic for global (RC1 pin) and local (RC2/RC3 pins) ON/OFF control—open for ON, short for OFF (local), short for ON, open for OFF (global)

6 Over-temperature handling: Pay attention to the T-Alarm signal (high level indicates over-temperature) and take cooling measures promptly to prevent damage

7 Mounting: Follow recommended mounting torque specs (e.g.,12Kgf-cm for AC input terminal) to ensure stable installation

8 Grounding: Ensure proper grounding of the power supply to avoid electrical interference and ensure safety
