产品特点 FEATURES

1 Modular power supply with 1200W maximum output and 6 slots, compatible with NMS-240 (single output) and NMD-240 (dual output) modules.

2 Wide input range: 90-264VAC (47-63Hz) or 120-370VDC, suitable for global applications.

3 High efficiency up to 91% (for H/K modules at 24V/48V full load) and power factor >0.95@230VAC full load, reducing energy consumption.

4 Compliance with multiple safety standards: Medical (2x MOPP isolation between primary and secondary) and ITE (ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 Ed.3.1, etc.), ensuring safe use in medical and industrial environments.

5 Comprehensive protection functions: Overload (constant current limiting), overvoltage (shut down, re-power to recover), overtemperature (auto-recover when cool), short circuit (hiccup mode or constant current limiting).

6 Flexible control options: Global/local ON/OFF control, remote sense (compensates up to 0.5V wiring drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), current sharing (for parallel operation of modules), and T-Alarm (overtemp signal).

7 Mechanical specifications: Dimensions 250x127x41mm (LxWxH), weight approximately 2kg, with a robust design for industrial use.

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound, blood analyzers), patient monitoring systems, and laboratory instruments (benefits from medical safety compliance and modularity for multiple power needs).

2 Industrial automation: PLCs, DCS systems, robotics, and factory automation lines (requires stable, modular power for diverse components and high reliability).

3 Test and measurement: Lab test equipment, signal generators, oscilloscopes, and electronic component testers (needs precise voltage/current control and programmable features).

4 Communication systems: Telecom base stations, network switches, and data center equipment (demands high efficiency, multiple outputs, and reliable operation).

5 LED applications: Large-scale LED displays, industrial LED lighting, and stage lighting systems (modular design allows adjusting outputs to match LED requirements).

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding to meet safety standards. Use M4 screws for front-end mounting with torque 7-10 Kgf-cm; avoid loose connections that may cause overheating.

2 Temperature derating: Follow the derating curve—reduce output current for ambient temperatures above 50°C. For output voltage <12V and ambient temperatures between -15°C and -30°C, derate output current to 90% of rated value.

3 Global ON/OFF setup: The shorting connector (RC1 pin6 to GND-P pin3) must be installed; otherwise, the unit will have no output.

4 Parallel operation: When paralleling NMS-240 modules, connect CS pins together, ensure output voltage difference between modules is <0.2V, total output power does not exceed 1200W, and use short, large-diameter wires. Do not use the PC (current programming) function in parallel mode.

5 Remote sense usage: Use twisted pairs for sense lines (+S/-S) to minimize noise interference. This function compensates for up to 0.5V voltage drop in load wiring.

6 Protection handling: If overvoltage protection triggers, re-power the unit to recover. Overtemperature protection will auto-recover when the unit cools down—check ventilation if this occurs frequently.

7 Wiring guidelines: Use 20-26AWG wires for control pins. For DC output terminals, use M3.5 screws with maximum torque of 10 Kgf-cm to ensure secure connections.
