产品特点 FEATURES

1 Modular power supply design: Front-end units (NMP650:4 slots, NMP1K2:6 slots) compatible with NMS-240 (single output) and NMD-240 (dual output) modules

2 Flexible control functions: Global ON/OFF (via RC1 pin), Local ON/OFF (via RC2/RC3 pins for individual modules), Remote Sense (+S/-S pins to compensate voltage drop on load wiring)

3 Programmable functions: Output Voltage Programming (PV pin adjusts voltage within specified range), Output Current Programming (PC pin trims current to 40-100% of rated value)

4 Monitoring signals: DC OK (TTL level indicating module output status), T-Alarm (overtemperature warning signal), CS (current sharing for parallel operation)

5 Auxiliary power outputs: +5V-AUX_P (2A for NMP1K2,1.5A for NMP650), Vcc2 (5V/10mA for NMS-240 modules)

6 Safety protections: Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP)

7 Parallel operation support: Up to 6 modules (NMP1K2) or4 (NMP650) with CS pins connected, ensuring current balance and total power compliance

8 Mechanical specifications: Standard dimensions (e.g., NMP1K2 front-end:250x127x41mm), recommended mounting torque (12Kgf-cm for AC terminals), compatible with 20-26AWG wires for output modules

使用场景 APPLICATIONS

1 Industrial automation systems: Providing multiple stable voltage outputs for control panels, sensors, and actuators

2 Test and measurement equipment: Programmable voltage/current outputs for component testing and validation

3 Telecom and data center racks: Redundant power supply via parallel operation to ensure continuous service

4 Embedded system development: Flexible power configuration for prototyping and debugging

5 Industrial IoT devices: Remote monitoring and control functions to support intelligent operation

6 Power distribution systems: Modular design allows easy expansion or replacement of output modules as per load requirements

注意事项 PRECAUTIONS

1 Ensure the shorting connector (RC1 to GND-P) is installed if global ON/OFF function is not used to enable output

2 For remote sense function, use twisted-pair wires for +S/-S pins to minimize signal interference

3 When programming voltage/current, refer to the product manual for exact pin connections and voltage ranges to avoid damage

4 Parallel operation guidelines: Connect CS pins of all modules, ensure output voltage difference <0.2V among modules, total power must not exceed 650W (NMP650) or1200W (NMP1K2)

5 Over temperature handling: When T-Alarm signal is triggered (high level), stop operation and cool down the unit to prevent damage

6 Mounting instructions: Use recommended screw sizes (M4 for front-end, M3.5 for output terminals) and torque values to ensure secure installation

7 Wire preparation: Trim output terminal wires to 10mm strip length to avoid short circuits between pins

8 Local ON/OFF control: Open RC2/RC3 pins to turn on module output, short to turn off (refer to pin assignments for exact connections)
