产品特点 FEATURES

1 Modular power supply design with 650W maximum output (4 slots for NMP650 series)

2 Wide input voltage range:90~264VAC or120~370VDC, supporting global AC inputs

3 High power factor:PF>0.95 at 230VAC full load, PF>0.98 at115VAC full load

4 Efficient performance:Up to91% efficiency at full load (with H/K modules at24V/48V nominal voltage)

5 Multiple output options:Supports single output modules (5V@36A,12V@20A,24V@10A,48V@5A) and dual output modules (up to30V@5A each, combined240W max)

6 Comprehensive protection features:Overload (constant current limiting), overvoltage (shut down and recover on repower), overtemperature (auto-recover after cooling)

7 Flexible control and monitoring:Remote sense (compensates up to0.5V wiring drop), DC OK signal (TTL level for output status), current sharing (for parallel operation), remote ON/OFF (global and local options)

8 Safety compliance:Meets medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1 etc.)

9 Compact mechanical design:Dimensions of250×89×41mm (L×W×H) for NMP650, easy to integrate into equipment

使用场景 APPLICATIONS

1 Medical devices:Suitable for diagnostic equipment, patient monitoring systems, and other medical applications requiring safe and stable power

2 Industrial automation:Powering PLCs, sensors, actuators, and control systems in manufacturing lines

3 Test and measurement:Providing precise and adjustable DC outputs for lab instruments and testing setups

4 Communication systems:Supporting routers, switches, and telecom equipment with multiple voltage requirements

5 LED lighting:Driving high-power LED arrays with stable current and voltage control

6 Embedded systems:Powering custom electronic devices with modular output needs

注意事项 PRECAUTIONS

1 Installation:Use recommended screw sizes (M4 for mounting, M3.5 for DC terminals) with specified torque (7~10Kgf-cm for mounting,10Kgf-cm for DC terminals;12Kgf-cm for AC terminals)

2 Derating guidelines:

3 When output voltage <12V and ambient temperature is between-15°C and-30°C, derate output current to90% of rated value

4 Follow derating curves for high ambient temperatures (e.g., reduce load at temps above50°C)

5 Remote sense:Connect +S/-S pins to load terminals to compensate for voltage drop in wiring (max0.5V)

6 Parallel operation:

7 Connect CS pins of all modules to ensure current balance; voltage difference between modules should be <0.2V

8 Total output power must not exceed650W for NMP650; maximum 4 modules in parallel

9 Use short, large-diameter wires for parallel connections to minimize voltage drop

10 ON/OFF control:

11 Global ON requires shorting RC1 (CN32-PIN6) to GND-P (CN32-PIN3) if not using external control

12 Local ON/OFF for modules:Open RC2 (for NMS-240) or RC2/RC3 (for NMD-240) to turn on, short to turn off

13 Safety:Ensure proper grounding; avoid operating beyond specified voltage/current limits; follow all safety standards during installation and maintenance

14 Storage:Store in a dry environment with temperature between-40°C and+85°C, relative humidity10~95% non-condensing
