产品特点 FEATURES

1 Modular design: NMP1K2 supports up to 6 output modules (max 1200W total), compatible with NMS-240 (single output:5V/36A,12V/20A,24V/10A,48V/5A) and NMD-240 (dual output:30V/5A each) modules

2 Safety compliance: Meets medical (2x MOPP between primary-secondary) and ITE standards, ensuring reliability in critical applications

3 Rich functional features: Remote sense (compensates up to 0.5V wiring drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), over-temperature/voltage/current protection (shutdown or constant current limiting)

4 Flexible control: Global ON/OFF (via RC1 pin) and local module ON/OFF (via RC2/RC3 pins), with open=ON/short=OFF logic

5 Current sharing capability: Supports parallel operation of NMS-240 modules (CS pins connected) for higher current, with max 6 modules for NMP1K2

6 Wide input range: AC90-264V or DC120-370V, suitable for global use

7 High efficiency: Up to 91% (with H/K modules at 24V/48V full load)

8 Auxiliary power: 5V/2A auxiliary output for NMP1K2 (AUX-P pin), and 5V/10mA for modules (Vcc2 pin)

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices needing medical safety certification (e.g., diagnostic instruments, patient monitors)

2 Industrial automation: Power supply for PLCs, sensors, actuators with multiple voltage requirements

3 Test & measurement systems: Provides stable, adjustable outputs for lab equipment and testing setups

4 Telecom & data centers: Modular power for network devices, servers, and storage systems

5 Embedded systems: Customizable power solutions for specialized electronic devices

6 Research & development: Flexible power supply for prototype testing and circuit design

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector (RC1 to GND-P) is properly installed to enable global output (without it, no output)

2 Temperature derating: For output voltages <12V and ambient temps between -15℃ to -30℃, derate output current to 90% of rated value; follow derating curves for different input voltages and temps

3 Parallel operation: When paralleling NMS-240 modules, keep output voltage difference <0.2V, connect CS pins together, ensure total power doesn't exceed1200W, and max 6 modules for NMP1K2

4 Parallel load requirement: Ensure total load is ≥10% of rated load to prevent some modules from entering standby mode

5 Remote sense usage: Connect +S/-S pins to load terminals to compensate for wiring voltage drop; do not leave sense pins open

6 ON/OFF control: Follow correct pin logic (global: RC1 short to GND-P=ON; local: RC2/RC3 open=ON) to avoid unintended output status

7 Over-temperature handling: If T-Alarm signal (high level) is triggered, check ventilation and load to prevent overheating; the power supply will shut down if temp exceeds safe limit and recover automatically when cooled

8 Wiring guidelines: Use appropriate wire sizes for input/output connections to minimize voltage drop and ensure safety
