产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC / 120~370VDC, frequency range 47~63Hz

3 High efficiency up to 91% (full load with H/K modules at nominal 24V/48V)

4 Compliance with medical safety standards (2x MOPP between primary and secondary) and ITE standards

5 Multiple protection functions: Overload (constant current limiting), overvoltage (shut down and recover on re-power), overtemperature (shut down and auto-recover after cooling)

6 Flexible control options: Global ON/OFF (via RC1 pin) and local ON/OFF (per module via RC2/RC3 pins)

7 Current sharing capability for parallel operation of NMS-240 modules, ensuring balanced load distribution

8 Auxiliary power outputs: 5V/2A (front-end) and 5V/10mA (per module)

9 DC OK signal (TTL level) indicating module output status, and T-Alarm signal for overtemperature warning

10 Adjustable output voltage (via PV pin) and current (via PC pin) for customization

11 Remote sense function (+S/-S pins) to compensate for voltage drop on load wiring up to 0.5V

使用场景 APPLICATIONS

1 Industrial automation systems requiring stable and customizable power supplies

2 Medical equipment meeting 2x MOPP safety requirements (e.g., diagnostic devices, monitoring systems)

3 Test and measurement instruments needing precise voltage/current control

4 Communication equipment and data centers (parallel operation for higher power demands)

5 Industrial control systems with multiple power needs (modular slots for different voltage outputs)

6 Precision electronic devices that benefit from remote monitoring (DC OK, T-Alarm signals)

7 Applications requiring wide input voltage compatibility (global power sources)

注意事项 PRECAUTIONS

1 Follow recommended mounting torque (12Kgf-cm for AC terminal, 10Kgf-cm for DC terminal) and screw sizes to ensure secure installation

2 Derate output current according to ambient temperature: For output voltage <12V and temp between -15°C to -30°C, derate to 90% of rated current; refer to derating curves for other conditions

3 When using remote sense, connect +S and -S pins to the load terminals to compensate for voltage drop

4 For parallel operation of NMS-240 modules: Connect CS pins mutually, ensure output voltage difference <0.2V, total power not exceeding 1200W, and do not use PC function

5 Blank slots must be filled with BLANK-NMS240 accessory to maintain safety and performance

6 Ensure the shorting connector is assembled (RC1 to GND-P) if global ON/OFF control is not used

7 Follow global/local ON/OFF control logic correctly: Global ON/OFF (RC1 open=OFF, short=ON); local ON/OFF (RC2/RC3 open=ON, short=OFF for NMS-240)

8 Avoid exceeding maximum load current for each module (e.g., NMS-240-05:36A, NMS-240-48:5A)

9 For detailed programming of output voltage/current and control functions, refer to the official function manual

10 Use appropriate wiring (short, large diameter) for parallel connections to minimize voltage drop
