产品特点 FEATURES

1 Modular design: NMP1K2 model supports up to 6 slots with total output power up to 1200W; compatible with single-output (NMS-240) and dual-output (NMD-240) modules (each module up to 240W)

2 Wide input voltage range: AC 90~264V or DC120~370VDC; frequency range 47~63Hz

3 High efficiency: Up to 91% at full load (when using H/K modules at nominal 24V/48V)

4 Multi-safety compliance: Meets IEC 60601-1 (medical standard with 2x MOPP isolation), IEC62368-1 (ITE standard), and EN60601-1-2 (EMC standard)

5 Comprehensive protection: Overload (constant current limiting or shut down), overvoltage (shut down, re-power to recover), overtemperature (auto-shut down and recover after cooling)

6 Flexible control options: Global ON/OFF (via RC1 pin) and local per-module ON/OFF (via RC2/RC3 pins; open circuit = ON, short circuit = OFF)

7 Advanced functions: Remote sense (compensates up to 0.5V wiring voltage drop), current sharing (for parallel module operation), output voltage/current programming (PV/PC pins), DC OK signal (TTL level to indicate output status), T-Alarm signal (overtemperature alert)

8 Auxiliary power outputs: Front-end provides 5V/2A auxiliary power; each module provides 5V/10mA auxiliary power

9 Adjustable output voltages: Modules support output voltage adjustment (e.g., NMS-240-05:3~6V, NMS-240-12:6~15V)

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety compliance, such as diagnostic instruments, patient monitors, and laboratory medical devices

2 Industrial automation: Power supply for PLC systems, industrial sensors, actuators, and control panels

3 Test and measurement: Stable power source for lab instruments like oscilloscopes, signal generators, and electronic test benches

4 Communication systems: Modular power for routers, switches, base stations, and telecom equipment with multiple DC voltage requirements

5 Data centers: Flexible power solution for server racks, storage devices, and network equipment

6 R&D and prototyping: Customizable DC power for research projects, prototype testing, and product development

注意事项 PRECAUTIONS

1 Installation: Ensure proper mounting torque for terminals (12Kgf-cm for AC input terminals, 10Kgf-cm for DC module terminals); keep the airflow direction unobstructed to maintain cooling efficiency

2 Control setup: Use the provided shorting connector (RC1 to GND-P) if not using external global ON/OFF control; for local module control, follow correct wiring of RC2/RC3 pins

3 Derating guidelines: When output voltage is below 12V and ambient temperature is between -15℃ and -30℃, derate output current to 90% of rated value; refer to derating curves for ambient temperature and input voltage conditions

4 Parallel operation: For current sharing, connect CS pins of all parallel modules; ensure output voltage difference between parallel modules is less than 0.2V; do not use the PC (output current programming) function when modules are in parallel; total output power should not exceed 1200W (NMP1K2)

5 Remote sense: Use twisted-pair cables for sense lines to minimize noise interference; connect sense lines directly to the load terminals for accurate voltage compensation

6 Safety precautions: Comply with local electrical safety regulations; ensure proper grounding before operation; avoid touching live parts during use; do not disassemble the unit without professional authorization
