产品特点 FEATURES

1 Modular design: NMP1K2 supports up to 6 output modules (NMS-240 single output:5V/36A,12V/20A,24V/10A,48V/5A; NMD-240 dual output: up to30V each, 240W max per module)

2 Flexible control: Global ON/OFF (RC1 pin) and local ON/OFF (per module via RC2/RC3 pins) for output management

3 Monitoring functions: DC OK signal (indicates module output status), T-Alarm (over-temperature alert), PV/PC pins for voltage/current programming

4 Remote sense: Compensates voltage drop on load wiring up to0.5V via +S/-S pins

5 Parallel operation: Supports up to6 modules in parallel with current sharing (CS pin), ideal for higher current needs

6 Safety protections: Over-voltage (OVP), over-current (OCP), over-temperature (OTP) protection; auto-recover for OTP when temp drops

7 Auxiliary power: +5V-AUX_P (2A for NMP1K2) and Vcc2 (5V/10mA for modules) for external circuits

8 Medical-grade isolation: 2x MOPP between primary and secondary, suitable for medical applications

使用场景 APPLICATIONS

1 Industrial automation: Configurable for various voltage requirements in PLCs, sensors, and actuators

2 Medical equipment: Isolated power supply for devices needing medical-grade safety (e.g., diagnostic tools, patient monitors)

3 Test & measurement: Programmable voltage/current for lab equipment (e.g., oscilloscopes, power analyzers)

4 Telecommunications: Reliable power for routers, switches, and base stations with parallel operation for redundancy

5 Data centers: Modular power for server racks, allowing easy expansion or replacement of modules

6 Embedded systems: Custom voltage configurations for embedded devices (e.g., IoT gateways, industrial PCs)

注意事项 PRECAUTIONS

1 Global ON/OFF setup: Ensure the shorting connector (RC1 to GND-P) is installed if not using the function; otherwise, no output

2 Local ON/OFF operation: For NMS-240, short RC2 to GND to turn off; open to turn on. For NMD-240, RC2 (V1) and RC3 (V2) control respective outputs

3 Remote sense: Connect +S/-S to load terminals to compensate voltage drop; do not leave unconnected

4 Parallel operation guidelines:

5 Output voltage difference between modules <0.2V

6 Total current ≤ sum of rated currents of modules, total power ≤1200W for NMP1K2

7 Use short, thick wires for parallel connections

8 If load <10% of rated, some modules may enter standby

9 Do not use PC function when modules are in parallel

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

11 Wiring: Follow pin assignments strictly for AC input (L/N/FG) and module outputs (+V/-V)

12 Protection reset: Power cycle to reset OVP/OCP; OTP auto-recovers when temp drops
