产品特点 FEATURES

Modular 1200W power supply (NMP1K2 model) with 6 slots for NMS-240 output modules, supporting multiple DC output configurations (5V/36A,12V/20A,24V/10A,48V/5A via C,E,H,K modules respectively)

1 Flexible control options: Global ON/OFF (RC1 pin) and local ON/OFF (RC2 pin) for individual modules; remote sense (+S/-S pins) compensates for voltage drop up to 0.5V

2 Programmable functions: Output voltage adjustment via PV pin and output current adjustment via PC pin

3 Monitoring capabilities: DC OK TTL signal (4.5-5.5V for ON,0-0.5V for OFF) indicates output status; T-Alarm signal alerts over-temperature conditions

4 Protection mechanisms: Over-voltage (shutdown), over-current (constant current limiting), over-load (shutdown), and over-temperature (shutdown with auto-recovery after cooling) protection

5 Parallel operation support: Current sharing (CS pin) for up to6 modules, enabling scalable power output up to1200W with balanced current distribution

6 Safety compliance: Features 2x MOPP isolation between primary and secondary, suitable for medical and industrial applications

使用场景 APPLICATIONS

Industrial automation: Powering PLCs, servo drives, sensors, and control systems in manufacturing lines

1 Medical equipment: Suitable for diagnostic devices (like ultrasound machines), patient monitors, and lab instruments (due to 2x MOPP isolation)

2 Test & measurement: Providing stable, adjustable power for electronic component testing and lab setups

3 Telecom infrastructure: Powering routers, switches, and communication modules in data centers or base stations

4 Industrial machinery: Supporting distributed power needs in packaging, printing, and material handling equipment

注意事项 PRECAUTIONS

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

1 For remote sense applications, twist the +S and -S wires in pairs to minimize electromagnetic interference

2 When parallelizing modules: Connect CS pins of all modules, maintain output voltage difference <0.2V between modules, use short and large-diameter wires, and avoid using the PC function

3 If the T-Alarm signal is high (4.5-5.5V), stop operation immediately, cool down the device, and check for ventilation issues before reuse

4 Follow the recommended voltage/current programming guidelines (PV/PC pins) to prevent damage to modules or connected devices

5 Mount the front-end unit using M4 screws with a torque of7-10 Kgf-cm, and use M3.5 screws for DC output terminals with a torque of10 Kgf-cm

6 For modules with output voltage <12V and ambient temperature between -15°C and -30°C, derate the output current to 90% of the rated value

7 When turning modules on/off locally (RC2 pin), ensure the open/short state is correct (open=ON, short=OFF) to avoid unintended output
