产品特点 FEATURES

1 Modular design with 6 slots (1200W max total power), supporting flexible output configurations via NMS-240 (single output:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output) modules.

2 Wide input voltage range:90~264VAC or120~370VDC, frequency47~63Hz, high power factor(PF>0.95@230VAC full load) and efficiency(up to91%@full load with H/K modules at24V/48V).

3 Compliance with medical(2x MOPP between primary-secondary) and ITE safety standards, ensuring reliability in critical applications.

4 Multiple protection functions:Overload(constant current limiting), overvoltage(shutdown & repower recovery), overtemperature(shutdown & auto-recovery after cooling).

5 Support for remote control(ON/OFF via dry contact), remote sense(compensates up to0.5V wiring drop), output voltage/current programming(PV/PC pins), and current sharing for parallel operation.

6 Built-in TTL-level DC OK signal(indicates module output status) and overtemperature alarm signal(T-Alarm), auxiliary power outputs(5V/2A for front-end,5V/10mA for modules).

使用场景 APPLICATIONS

1 Industrial automation systems:Powering PLCs, DCS, servo drives, and other control components requiring multiple stable DC voltages.

2 Medical equipment:Suitable for devices needing medical safety compliance(like diagnostic instruments, patient monitoring systems) due to2x MOPP isolation.

3 Test and measurement devices:Providing precise, adjustable DC outputs for lab equipment, electronic component testing, and prototype development.

4 Communication infrastructure:Powering routers, switches, base stations, and other network devices requiring reliable and flexible power supplies.

5 Industrial control panels:Supporting various sensors, actuators, and display units with different voltage requirements.

6 Parallel operation setups:Used in applications needing higher power capacity(up to1200W) via current sharing among modules.

注意事项 PRECAUTIONS

1 Derating requirement:When output voltage is below12V and ambient temperature is between-15℃ to-30℃, reduce output current to90% of rated value; derate according to derating curve at high ambient temperatures.

2 Proper grounding:Ensure effective grounding of FG terminals to prevent electric shock and interference.

3 Remote sense usage:For remote sense function, connect +S/-S pins to load terminals to compensate for voltage drop on wiring; avoid open circuits on sense lines.

4 Parallel operation guidelines:When paralleling modules, connect CS pins mutually, ensure output voltage difference<0.2V among modules, total current not exceeding rated sum, and use short/large-diameter wires.

5 Over-temperature handling:If T-Alarm signal is triggered(high level), check cooling conditions(airflow, ambient temp) and reduce load if necessary to prevent shutdown.

6 Global/local ON/OFF control:Ensure shorting connector(RC1 to GND-P) is installed for normal operation if global ON/OFF is not used; local control via RC2/RC3 pins for individual modules.
