使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, control panels, robotic systems

2 Medical equipment: Patient monitors, diagnostic devices (non-life-supporting) due to medical safety compliance

3 Telecommunications: Routers, switches, base stations, communication modules

4 Test & measurement: Lab equipment, test benches requiring adjustable multi-voltage outputs

5 Data centers: Server racks, storage systems, network infrastructure

6 LED lighting: High-power LED arrays, street lighting, industrial lighting

7 Renewable energy: Solar/wind converters for stable DC power distribution

注意事项 PRECAUTIONS

1 Installation: Use M4 screws for mounting (torque7-10 Kgf-cm); ensure proper grounding via FG terminal

2 Wiring: Control signals use20-26AWG wires; power lines use appropriate gauge to minimize voltage drop

3 Wiring: Remote sense lines should be twisted pairs; connect +S to +V load terminal and -S to -V load terminal

4 Operating conditions: Ambient temp range -30~+70°C; derate output current per curve if temp exceeds50°C

5 Operating conditions: For output voltage <12V and temp -15~-30°C: derate current to90% of rated value

6 Parallel operation: Only NMS-240 modules can be paralleled; max6 modules for NMP1K2

7 Parallel operation: Ensure output voltage difference between modules <0.2V before parallel

8 Parallel operation: Connect CS pins together for current balancing; total output power ≤1200W

9 Parallel operation: Remote ON/OFF must control all parallel modules simultaneously

10 Protection: Over-temperature alarm (T-Alarm high=4.5-5.5V) indicates overheating; check cooling

11 Protection: Overvoltage/overload: If output shuts down, disconnect load and排查 faults before re-powering

12 Protection: Short circuit: Hiccup mode for5V/12V modules, constant current limiting for others

13 Safety: Follow medical guidelines for medical use; leakage current <400uA at 264VAC

14 Safety: Do not touch live parts when powered on; avoid operating without proper insulation

15 Safety: Do not disassemble; contact Meanwell for maintenance
