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

4 Multiple output module options: single output (5V/36A,12V/20A,24V/10A,48V/5A) and dual output (30V/5A each) modules, each up to240W

5 Adjustable output voltage ranges (e.g.,5V module:3~6V,12V:6~15V,24V:15~30V,48V:30~55V)

6 Comprehensive protection functions: overvoltage (OVP), overcurrent (OCP), overtemperature (OTP), overload (OLP)

7 Remote monitoring and control capabilities: DC OK signal (TTL level), remote sense (+S/-S), remote ON/OFF (local/global)

8 Current sharing function for parallel operation of modules to balance load distribution

9 Compliance with safety standards: medical (2x MOPP between primary and secondary) and ITE (UL62368-1, EN60601-1 Ed3.1, etc.)

10 Auxiliary power outputs:5V/2A (front-end) and5V/10mA (module-level)

11 TTL alarm signal for overtemperature (high when over limit, low when normal)

12 Derating capability for harsh environments (e.g.,90% current at-15°C~-30°C for Vo<12V)

使用场景 APPLICATIONS

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

2 Medical equipment: Compliant with medical safety standards, suitable for diagnostic devices and treatment equipment

3 Test and measurement systems: Modular power needs for various testing instruments

4 Telecommunications: Power for base stations, communication nodes, and network devices

5 Data centers: Parallel operation setups for high-power, redundant power systems

6 Industrial control systems: Harsh environment applications requiring wide input range and derating capabilities

7 Laboratory setups: Adjustable voltage outputs for R&D and prototype testing

8 Redundant power systems: Parallel modules to ensure continuous operation in critical applications

注意事项 PRECAUTIONS

1 Mounting: Follow recommended torque (12Kgf-cm for front-end,10Kgf-cm for output terminals) to prevent loose connections and overheating

2 Remote Sense: Correctly connect +S/-S pins to compensate for voltage drop (max0.5V) on load wiring

3 Parallel Operation: Connect CS pins of all modules, ensure output voltage difference <0.2V between modules; total output power must not exceed1200W; use short, large-diameter wires for parallel connections; remote control must turn all parallel modules on/off simultaneously; do not use PC (current programming) function in parallel

4 Derating: Reduce output current to90% when ambient temperature is between -15°C and-30°C (for Vo<12V)

5 Protection: Overvoltage/overload protection may require re-powering to recover; some modules use hiccup mode for short protection

6 Global ON/OFF: Ensure shorting connector (RC1 to GND-P) is assembled to enable power output

7 Local ON/OFF: For NMS-240 modules, open RC2 for ON, short for OFF; for NMD-240, open RC2/RC3 for ON

8 Blank Slots: Use BLANK-NMS240 accessory for empty slots to maintain safety and airflow

9 Connectors: Use compatible HRS DF11 series connectors for control pins to ensure reliable connections

10 Leakage Current: Ensure system grounding is proper to handle leakage current (<400uA at 264VAC)

11 Derating Curves: Refer to the specification sheet for derating under different ambient temperatures and input voltages
