产品特点 FEATURES

1 Modular design with 6 slots (NMP1K2) supporting up to 1200W total output power

2 Wide input voltage range: 90~264VAC / 120~370VDC, compatible with global power grids

3 Multiple output module options: Single output (NMS-240 series:5V/36A,12V/20A,24V/10A,48V/5A) and dual output (NMD-240 series:30V/5A x2) modules, each up to 240W

4 Compliance with strict safety standards: ANSI/AAMI ES60601-1 (medical), UL62368-1, IEC60601-1, IEC62368-1, ensuring reliability in critical applications

5 Comprehensive protection functions: Overload (constant current limiting), overvoltage (shutdown and re-power recovery), overtemperature (automatic shutdown and recovery after cooling)

6 Flexible control options: Global (entire unit) and local (individual module) ON/OFF control via dry contact or electrical signal

7 Advanced features: Remote sense (compensates voltage drop up to 0.5V), current sharing (for parallel operation of modules), DC OK signal (TTL level indicating output status), output voltage/current programming (adjustable via external voltage)

8 High efficiency up to 91% (typical at full load with H/K modules at 24V/48V), reducing energy consumption and heat generation

9 Wide operating temperature range: -30°C to +70°C (with appropriate derating as per curves)

10 Compact mechanical dimensions: 250mm (L) ×127mm (W) ×41mm (H), saving installation space

11 EMC compliance: Meets EN55032 Class B (emission) and EN61000-4 series (immunity), minimizing interference with other equipment

注意事项 PRECAUTIONS

1 Installation:

2 Ensure proper grounding to prevent electric shock and reduce interference

3 Insert modules firmly into the slots until they click into place; use BLANK-NMS240 covers for empty slots to prevent dust accumulation and ensure proper heat dissipation

4 Follow the recommended mounting torque (7~10 Kgf-cm for M4 screws) to avoid damage to the unit

5 Operation:

6 Adhere to derating curves for ambient temperature and input voltage; reduce output current by 90% when output voltage is below 12V and temperature is between -15°C and -30°C

7 Do not exceed the maximum total output power (1200W for NMP1K2) or individual module power (240W per module)

8 Ensure the shorting connector (RC1 to GND-P) is installed if global ON/OFF control is not used; otherwise, the unit will have no output

9 For remote sense function, use twisted-pair cables to minimize noise and ensure accurate voltage compensation

10 Maintenance:

11 Regularly clean the ventilation slots to prevent dust buildup, which can cause overheating

12 Check for loose connections or damaged cables periodically to ensure stable operation

13 Do not open the unit or modify internal components; contact professional service personnel for repairs

14 Safety:

15 Disconnect the power supply from the AC/DC source before performing any installation, maintenance, or module replacement

16 Use cables with appropriate current capacity to avoid overheating and fire hazards

17 Comply with local electrical safety codes and regulations when installing and using the product

18 Avoid exposing the unit to moisture, dust, corrosive gases, or extreme temperatures beyond the specified range
