产品特点 FEATURES

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

2 Wide input voltage range:90~264VAC or120~370VDC, frequency range47~63Hz

3 High efficiency up to91% (full load with H/K modules at24V/48V nominal voltage)

4 Compliance with medical (2x MOPP isolation) and ITE safety standards (ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 etc.)

5 Multiple protection functions:Overload (constant current limiting), overvoltage (shutdown, re-power to recover), overtemperature (auto-recover after cooling)

6 Support for remote control features:Global/local ON/OFF, remote sense (compensate up to0.5V drop), output voltage/current programming

7 Current sharing capability for parallel operation of modules to increase power output

8 Auxiliary power outputs:5V-AUX-P (2A for NMP1K2) and Vcc2 (5V/10mA for modules)

9 DC OK signal (TTL level) to indicate module output status

使用场景 APPLICATIONS

1 Industrial automation:Power supply for PLCs, DCS systems, sensors, and actuators

2 Medical devices:Suitable for low-risk medical equipment like patient monitors, diagnostic tools (due to medical safety compliance)

3 Telecommunications:Powering network routers, switches, and base station equipment

4 Test and measurement:Stable power for precision instruments such as oscilloscopes and signal generators

5 Data centers:Modular power solution for server racks and storage systems

6 Renewable energy systems:Compatible with DC input from solar panels or wind turbines

注意事项 PRECAUTIONS

1 Mounting:Use M4 screws with7~10 Kgf-cm torque; ensure proper grounding for safety

2 Temperature derating:Follow the derating curve—reduce output current at higher ambient temperatures; when output voltage <12V and temp is between -15°C to -30°C, derate to90% of rated current

3 Remote sense:Use twisted pair cables for sense lines to minimize electromagnetic interference; do not exceed0.5V voltage drop compensation

4 Parallel operation:Connect CS pins of all modules; ensure output voltage difference between parallel modules is <0.2V; total power should not exceed1200W

5 ON/OFF control:For global ON/OFF, if not using external control, short RC1 (CN32-PIN6) to GND-P (CN32-PIN3); local module ON/OFF via RC2 (open=ON, short=OFF)

6 Protection handling:In case of overtemperature shutdown, wait for the unit to cool down before restarting; overvoltage/overload protection requires re-powering the unit to recover

7 Wiring:Use appropriate wire gauge for input/output terminals to avoid voltage drop and overheating
