产品特点 FEATURES

1 Modular design with 6 slots (NMP1K2 model) supporting up to 1200W total output power

2 Compatible with single-output (NMS-240) and dual-output (NMD-240) modules, offering adjustable voltages (5V/36A,12V/20A,24V/10A,48V/5A, dual 30V/5A)

3 Wide input voltage range:90~264VAC or120~370VDC; frequency range:47~63Hz

4 High power factor (PF>0.95@230VAC full load) and efficiency up to91% (with H/K modules at24V/48V nominal voltage)

5 Compliance with multiple safety standards: IEC60601-1 (medical), UL62368-1, EN60601-1-2 (EMC for medical), SEMI F47

6 Built-in protection functions: over temperature (automatic recovery after cooling), over voltage (shutdown, repower to recover), overload (constant current limiting), short circuit (hiccup or constant current mode)

7 Support for remote sense (compensates up to0.5V voltage drop), current sharing (for parallel operation), DC OK signal (TTL level indicating output status), output voltage/current programming (PV/PC pins)

8 Global and local ON/OFF control: global via RC1 pin, local via RC2/RC3 pins for individual modules

9 Auxiliary power outputs:5V/2A (front-end) and5V/10mA (modules)

使用场景 APPLICATIONS

1 Industrial automation systems requiring flexible power configurations for various components

2 Medical equipment (e.g., diagnostic devices, patient monitors) compliant with medical safety standards

3 Test and measurement instruments needing stable, adjustable DC power supplies

4 Communication infrastructure (e.g., routers, switches) with rack-mounted power requirements

5 Industrial control systems (PLCs, DCS) where modular power distribution is essential

6 Parallel operation setups for high-power applications (e.g., server farms, data centers)

7 Equipment with remote monitoring needs (using DC OK and T-Alarm signals)

注意事项 PRECAUTIONS

1 Derating is required: when output voltage <12V and ambient temp between-15°C to-30°C, reduce output current to90% of rated value; follow derating curves for high ambient temps

2 Ensure the shorting connector (RC1 to GND-P) is installed for normal operation (if global ON/OFF is not used)

3 For parallel operation: connect CS pins of all modules, keep output voltage difference <0.2V, total power ≤1200W (NMP1K2), and avoid using PC function

4 Remote sense lines should be twisted pairs to minimize noise interference

5 Over temperature alarm (T-Alarm signal) indicates internal temp exceeds limits; take cooling measures when triggered

6 When modules are in parallel, use short, large-diameter wires for connections to ensure current balance

7 Blank slots must be filled with BLANK-NMS240 accessories to maintain proper airflow and safety

8 Follow the correct ON/OFF control logic (global/local) to avoid unexpected output status
