产品特点 FEATURES

1 Modular design: 6-slot 1200W front-end, compatible with NMS-240 series single-output modules (5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 dual-output modules, offering flexible voltage and current configurations

2 Wide input range: 90~264VAC or 120~370VDC, suitable for global power grids

3 High efficiency: Up to 91% (full load with H/K modules at nominal 24V/48V), reducing energy loss

4 Multiple safety compliances: Meets medical (2x MOPP between primary and secondary) and ITE standards, ensuring safe operation

5 Comprehensive protection: Over-temperature (auto-recover after cooling), over-voltage (shutdown, re-power to recover), overload (constant current limiting) protection

6 Flexible control options: Global ON/OFF (via RC1-GND-P) and local ON/OFF (per module via RC2-GND), remote sense (compensates up to 0.5V wiring drop), DC OK signal (TTL level)

7 Parallel operation support: Current sharing function allows parallel connection for higher power, with clear safe operation guidelines

8 Auxiliary power outputs: 5V/2A front-end auxiliary power and 5V/10mA module auxiliary power for external control circuits

使用场景 APPLICATIONS

1 Industrial automation: Power supply for PLCs, sensors, actuators with varying voltage requirements

2 Medical equipment: Suitable for devices needing medical-grade isolation (2x MOPP) like diagnostic instruments

3 Test and measurement: Flexible modular outputs for testing electronic components (ICs, circuit boards)

4 Data centers: Reliable power for server peripherals and network devices with multiple power needs

5 Telecom systems: Stable power for communication equipment (routers, switches) with modular configurations

6 Laboratory environments: Ideal for R&D setups requiring diverse voltage outputs for prototype testing

注意事项 PRECAUTIONS

1 Mounting and wiring: Follow specified torque for terminals (AC input: max12Kgf-cm; DC output: max10Kgf-cm), use twisted pairs for remote sense lines (+S/-S)

2 Parallel operation: Connect CS pins of modules; ensure output voltage difference <0.2V; total current ≤ sum of rated currents; total power ≤1200W; use short/large diameter wires; remote control must turn all modules on/off simultaneously

3 Temperature derating: For output voltage <12V and ambient temp -15°C~-30°C, derate current to90% of rated

4 Global ON/OFF: Assemble shorting connector (RC1 to GND-P) if not using global control; else no output

5 Local ON/OFF: NMS-240: open RC2 to GND (ON), short (OFF); NMD-240: open RC2/RC3 to GND1/GND2 (ON), short (OFF)

6 Over-temperature: If T-Alarm signal is high (4.5-5.5V), check internal temp and reduce load

7 Safety grounding: Ensure proper grounding to meet leakage current requirements (<400uA/264VAC)
