产品特点 FEATURES

1 Modular design with multiple output options: Supports single output (NMS-240) and dual output (NMD-240) modules, with voltage options including 5V,12V,24V,48V and adjustable ranges for different applications.

2 Flexible control functions: Offers global (entire unit) and local (specific module) ON/OFF control; Supports output voltage programming (PV) and output current programming (PC) for precise adjustment.

3 Comprehensive protection mechanisms: Includes over-temperature (T-Alarm signal), over-voltage (O.V.P), over-current (O.C.P), and over-load (O.L.P) protection; Automatically recovers or shuts down as per protection type.

4 Remote monitoring and adjustment: Provides remote sense (compensates voltage drop up to 0.5V), DC OK signal (indicates output status via TTL level), and current sharing (CS) for parallel operation.

5 Compliance with safety standards: Meets medical (ANSI/AAMI ES60601-1 Ed.3.1) and industrial (UL62368-1, IEC62368-1) safety standards, suitable for various high-reliability applications.

6 Auxiliary power supply: Equipped with auxiliary voltage outputs (e.g.,5V/2A for NMP1K2,5V/10mA for modules) to support external control circuits.

7 Parallel operation capability: Allows parallel connection of up to 4 (NMP650) or 6 (NMP1K2) modules for higher power output, with current balance via CS pins.

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety compliance (e.g., diagnostic instruments, patient monitoring systems).

2 Industrial automation: Used in PLCs, motor drives, sensors, and control systems needing multiple stable power outputs.

3 Test and measurement instruments: Provides precise and adjustable power for lab equipment, oscilloscopes, and signal generators.

4 Communication systems: Supports rack-mounted communication equipment, routers, and switches with flexible power configurations.

5 Other applications: Ideal for any scenario needing modular, reliable, and configurable DC power supplies, such as research labs and industrial control panels.

注意事项 PRECAUTIONS

1 Installation requirement: Ensure the shorting connector is properly installed (RC1 to GND-P) if global ON/OFF control is not used; Otherwise, the unit will have no output.

2 Derating guidelines: When output voltage <12V and ambient temperature ranges from -15°C to -30°C, derate output current to 90% of rated value; Follow derating curves for different ambient temperatures and input voltages.

3 Parallel operation rules: When connecting modules in parallel, ensure output voltage difference between modules <0.2V; Do not exceed total power limits (650W for NMP650,1200W for NMP1K2); Do not use PC function for parallel modules; Connect CS pins and GND pins mutually for current balance.

4 Remote sense usage: Twist the sense lines (+S and -S) in pairs to minimize interference when using remote sense.

5 Mounting precautions: Follow recommended mounting torque (e.g.,12Kgf-cm for AC input terminal,7~10Kgf-cm for mounting screws) to avoid mechanical damage.

6 Dual output module control: For NMD-240 modules, use separate ON/OFF controls (RC2 for V1, RC3 for V2) to manage each output independently.

7 Temperature alarm: Pay attention to T-Alarm signal (high level indicates over-temperature) and take necessary cooling measures to prevent damage.
