产品特点 FEATURES

1 Modular power supply from MW (Meanwell) with model NMP1K2-KKEHCC-00, supporting up to 1200W total output power via 6 slots

2 Wide input voltage range: 90~264VAC or 120~370VDC, compatible with global power grids; input frequency range is 47~63Hz

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

4 Compliance with multiple safety standards: ANSI/AAMI ES60601-1 (medical), UL62368-1, TUV EN60601-1, EN62368-1, IEC60601-1, IEC60950-1 (ITE), and EAC TP TC004

5 Rich protection mechanisms: Overload (constant current limiting), Over Voltage (shut down output, recover by re-powering), Over Temperature (auto shut down when overheated, recover after cooling)

6 Versatile functional support: Remote sense (compensate voltage drop up to 0.5V), output voltage programming (PV), output current programming (PC), DC OK signal (TTL level indicating output status), current sharing (CS for parallel operation), and global/local ON/OFF control

7 Auxiliary power outputs: Front-end provides 5V/2A, each module offers 5V/10mA for control circuits

8 Compact mechanical design: Dimensions of NMP1K2 front-end are 250×127×41mm (L×W×H), net weight approximately 2kg, easy to integrate into various systems

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, servo drives, sensors, and control panels requiring multiple DC outputs

2 Medical equipment: Suitable for devices compliant with medical safety standards (2x MOPP isolation), like diagnostic instruments, patient monitors, and laboratory equipment

3 Test and measurement instruments: Providing stable, adjustable DC power for electronic component testing, circuit debugging, and performance validation

4 Communication and data center applications: Supporting servers, switches, routers, and telecom equipment with reliable modular power supply

5 Industrial control systems: Adaptable to various industrial environments needing flexible power configurations and high reliability

注意事项 PRECAUTIONS

1 Remote sense usage: Ensure sense lines are twisted pairs to reduce electromagnetic interference and maintain accurate voltage compensation

2 Parallel operation guidelines: Connect CS pins of all parallel modules; output voltage difference among modules should be less than 0.2V; total output power must not exceed 1200W (NMP1K2); use short, large-diameter wires for parallel connections; avoid using current programming (PC) function in parallel mode

3 Temperature derating: Follow the derating curve—for output voltage <12V and ambient temperature between -15°C and -30°C, reduce output current to 90% of rated value; derate load appropriately at higher ambient temperatures to prevent overheating

4 Over temperature monitoring: Pay attention to the T-Alarm signal (TTL level) which indicates internal temperature status; take measures to cool the system if the signal goes high

5 ON/OFF control: If global ON/OFF function is not used, ensure the shorting connector (RC1 to GND-P) is properly assembled; local ON/OFF for modules is controlled by RC2 (open=ON, short=OFF)

6 Safety compliance: Only use the product in applications that meet its certified safety standards; do not operate outside the specified input voltage/frequency ranges

7 Installation: Follow the mechanical specification for mounting (M4 screws, torque 7~10 Kgf-cm) to ensure stable installation
