产品特点 FEATURES

1 Modular design: NMP1K2 series supports up to 6 slots, compatible with NMS-240 (single output, max 240W per module) and NMD-240 (dual output) modules for flexible power configuration

2 High power capacity: Total output power up to 1200W to meet multi-device power demands

3 Flexible control options: Global ON/OFF (via RC1 and GND-P) and local ON/OFF (per module via RC2/RC3 and GND) for precise power management

4 Advanced monitoring signals: DC OK (indicates module output status), T-Alarm (over-temperature warning) and LED indicators for real-time operation tracking

5 Programmable functions: Output voltage programming (PV pin) and constant current level programming (PC pin) for NMS-240 modules to adapt to diverse load requirements

6 Remote sense capability: Compensates voltage drop on load wiring up to 0.5V via +S/-S pins, ensuring stable output at the load end

7 Parallel operation support: NMS-240 modules can be paralleled (up to 6 for NMP1K2) with current sharing (CS pin) to enhance power capacity and system reliability; total current should not exceed the sum of rated currents of parallel modules, and total power ≤1200W

8 Auxiliary power outputs: +5V-Aux_P (2A for NMP1K2) and Vcc2 (5V/10mA for NMS-240) to power control circuits or accessory devices

9 Comprehensive protection mechanisms: Over-temperature protection (shuts down output and recovers automatically when cooled), over-voltage protection (constant current limiting or shutdown), and over-load protection to safeguard the power supply and connected equipment

使用场景 APPLICATIONS

1 Industrial automation systems: Provides multiple stable power outputs for PLCs, sensors, actuators and control panels, supporting flexible configuration via modular slots

2 Test and measurement equipment: Programmable voltage/current features and precise load regulation meet the strict power requirements of lab instruments and testing devices

3 Telecommunications and data center applications: Parallel operation capability ensures high reliability and scalability for network switches, routers and server accessories

4 Rack-mounted electronic systems: Compact modular design fits rack installations, optimizing space usage while delivering sufficient power for multiple components

5 Custom electronic projects: Flexible ON/OFF control and auxiliary power outputs support diverse DIY and prototype development needs

6 Industrial control cabinets: Modular structure and multiple outputs adapt to the complex power demands of cabinet-mounted devices

注意事项 PRECAUTIONS

1 Ensure the shorting connector (connecting RC1 to GND-P) is installed; otherwise, the power supply will have no output

2 Follow derating guidelines: When output voltage <12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of the rated value

3 For parallel operation: Connect CS pins of all modules, ensure output voltage difference between parallel modules <0.2V, total power ≤1200W (NMP1K2), and do not use the PC (constant current programming) function on parallel modules

4 Proper wiring practices: Use short, large-diameter wires for parallel connections to minimize voltage drop; twist sense lines (+S/-S) in pairs for remote sense applications

5 Temperature management: Monitor the T-Alarm signal to prevent over-temperature damage; ensure adequate ventilation for heat dissipation

6 Control logic compliance: Understand global vs local ON/OFF control logic to avoid unintended power status changes (global: RC1 open=OFF, short=ON; local: RC2 open=ON, short=OFF for NMS-240)

7 Programming limits: Do not exceed the specified voltage/current ranges when using PV (voltage programming) or PC functions to prevent module damage

8 Safety first: Disconnect power before performing wiring or module replacement operations
