产品特点 FEATURES

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

1 Wide input voltage range:90~264VAC or 120~370VDC, suitable for global applications

2 High efficiency up to 91% (when using H/K modules at nominal 24V/48V full load)

3 Compliance with medical (2x MOPP between primary and secondary) and ITE safety standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

4 Multiple protection functions: Overload (constant current limiting or hiccup mode), overvoltage (shutdown and recover on repower), overtemperature (shutdown and auto-recover after cooling)

5 Support for remote sense (compensates up to 0.5V voltage drop on load wiring)

6 Output voltage programming (PV pin) and constant current level programming (PC pin) for flexible adjustment

7 DC OK signal (TTL level) to indicate output status, and T-Alarm signal for overtemperature alert

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

9 Global (entire unit) and local (individual module) ON/OFF control options for flexible power management

使用场景 APPLICATIONS

Medical equipment: Diagnostic devices (e.g., ultrasound machines), patient monitors, and other medical devices requiring stable, compliant power supplies

1 Industrial automation: PLC systems, motor drives, sensors, and control panels needing multiple DC voltage outputs

2 Test and measurement instruments: Oscilloscopes, signal generators, and lab equipment that demand precise and reliable power

3 Telecom and data communication: Routers, switches, and base stations requiring multiple voltage levels for different components

4 Other applications: Broadcast equipment, industrial computers, and embedded systems that need modular and scalable power solutions

注意事项 PRECAUTIONS

Derating requirements: When output voltage is below 12V and ambient temperature is between -15°C to -30°C, output current must be derated to 90% of rated current; follow derating curves for high ambient temperatures

1 Blank slot handling: Empty slots must be filled with BLANK-NMS240 accessories to ensure proper operation and safety; contact Meanwell for details

2 Global ON/OFF setup: The shorting connector (from RC1 to GND-P) must be installed for the unit to output power; remove or disconnect for global OFF

3 Remote sense usage: Connect +S/-S pins to load terminals to compensate for voltage drop on wiring; do not leave these pins open

4 Parallel operation guidelines: When paralleling NMS-240 modules, connect CS pins together, ensure output voltage difference between modules is less than 0.2V, total output power does not exceed 1200W, use short large-diameter wires for parallel connections, and avoid using PC function in parallel mode

5 Overtemperature monitoring: Utilize the T-Alarm signal (TTL level) to monitor internal temperature; high signal indicates over-temperature, low indicates normal

6 Safety compliance: Install and operate the power supply in accordance with applicable safety standards and local regulations; avoid exposure to moisture or extreme environments beyond specified ranges
