6 Multiple protection functions: Overload (shut down, repower to recover), overvoltage (constant current limiting), overtemperature (auto recovery after cooling), earth leakage current <400uA/264VAC

7 Rich functionalities: Remote sense (compensate voltage drop up to 0.5V), global/local remote ON/OFF control, output voltage programming (PV), output current programming (PC), DC OK signal (TTL level), current sharing (for parallel operation of NMS-240 modules)

8 Auxiliary power outputs: 5V/2A (front-end NMP1K2),5V/10mA (NMS-240 modules)

9 Mechanical specs: Dimensions 250×127×41mm (L×W×H), weight ~2kg, vibration resistance (10-500Hz,2G,10min per cycle along X/Y/Z axes)

2 Medical equipment: Suitable for diagnostic tools, patient monitors, and other medical devices compliant with ES60601-1 standards

3 Telecommunications: Providing stable power for network switches, routers, and communication modules

4 Test and measurement: Supporting lab instruments that require adjustable, high-precision power

5 Data centers: Modular power solution for server racks or peripheral devices

6 LED lighting: High-efficiency power supply for large-scale LED installations

7 Renewable energy systems: Integration with solar or wind power converters (wide DC input range supports varying energy sources)

注意事项 PRECAUTIONS

1 Installation:

2 Ensure proper grounding via FG terminal to meet safety requirements

3 Use recommended screws (M4 for front-end AC terminal, M3.5 for module DC terminal) with specified torque (12Kgf-cm for front-end AC,10Kgf-cm for module DC)

4 Fill empty slots with BLANK-NMS240 to maintain safety and airflow

5 Operation:

6 Global ON/OFF: Short RC1 (CN32-PIN6) to GND-P (CN32-PIN3) for power ON; open the connection for OFF (default requires the included shorting connector)

7 Local ON/OFF: For NMS-240 modules, open RC2 (CN81-PIN3) from GND (CN81-PIN1/2) for ON; short for OFF. For NMD-240 modules, open RC2/RC3 from respective GNDs for ON; short for OFF

8 Remote sense: Connect +S/-S pins to load terminals to compensate voltage drop (max 0.5V)

9 Parallel operation (NMS-240 only):

10 Connect CS pins of all parallel modules together

11 Ensure output voltage difference between modules is <0.2V

12 Total output current ≤ sum of rated currents of parallel modules; total power ≤1200W

13 Use short, large-diameter wires for parallel connections

14 Remote control must turn all parallel modules ON/OFF simultaneously

15 Do not use output current programming (PC) function in parallel mode

16 Temperature derating:

17 For output voltage <12V and ambient temperature -15~-30°C, derate output current to 90% of rated value

18 For ambient temperature above 50°C, refer to the derating curve to reduce load percentage

19 Maintenance:

20 Monitor T-Alarm signal (TTL level: high=overtemperature, low=normal) to prevent overheating

21 Keep ventilation slots clear to ensure proper airflow

22 Do not operate the power supply without the required shorting connector (for global ON/OFF) unless using external control
