产品特点 FEATURES

1 Modular structure: NMP1K2 front-end with 6 slots, compatible with NMS-240 (single output, up to 240W) and NMD-240 (dual output, up to 240W) modules

2 Wide input range: 90~264VAC or 120~370VDC, frequency 47~63Hz

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

4 Safety compliance: Meets medical (2x MOPP isolation between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, etc.)

5 EMC compliance: EN55032 Class B (emission) and EN61000-4 series (immunity) to reduce electromagnetic interference

6 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down, re-power to recover), overtemperature (auto-recover after cooling), short circuit protection

7 Flexible control: Global/local ON/OFF, remote sense (compensates up to 0.5V voltage drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level output status), current sharing for parallel operation

8 Auxiliary power: Front-end provides 5V/2A; modules offer 5V/10mA (Vcc2)

9 Low ripple: Modules have low ripple (e.g., NMS-240-24 max 150mVp-p)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators with multiple voltage requirements

2 Medical equipment: Suitable for devices needing isolated power (2x MOPP compliant)

3 Test & measurement: Customizable voltage/current outputs for component testing

4 Telecom systems: Powering routers, switches, and network devices

5 Lab research: Flexible power configurations for prototype development

6 Broadcast media: Supporting audio/video gear with varying power needs

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding (FG terminal). Use M4 screws for mounting with torque 7~10 Kgf-cm

2 Derating: When output voltage <12V and temp -15~-30°C, derate current to 90% of rated. Refer to derating curves for high temp (>50°C)

3 Control: Global ON/OFF requires shorting RC1 to GND-P if no external control. Local ON/OFF: Open RC2/RC3 to turn on, short to turn off

4 Parallel operation: Connect CS pins of modules; voltage difference <0.2V. Total power ≤1200W

5 Blank slots: Must fill with BLANK-NMS240 modules

6 Safety: Disconnect AC power before installation/service. Avoid touching live parts when powered on

7 Maintenance: Keep unit clean to maintain airflow; avoid humid/corrosive environments
