产品特点 FEATURES

1 Modular design: NMP1K2 base unit with 6 slots, supports flexible configuration of single-output (NMS-240) or dual-output (NMD-240) modules, each up to 240W

2 Wide input compatibility: AC 90-264V or DC120-370V, 47-63Hz; high power factor (PF>0.95@230VAC full load, PF>0.98@115VAC full load) and high efficiency (up to91% typical)

3 Comprehensive safety compliance: Meets medical standards (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, EN62368-1, IEC60601-1 Ed3.1, IEC62368-1, TUV IEC60950-1, EAC TP TC004)

4 Rich protection mechanisms: Overload (constant current limiting or shut-down), overvoltage (shut-down, repower to recover), overtemperature (auto shut-down and recovery after cooling), short circuit (hiccup mode or constant current limiting)

5 Advanced functional support: Remote sense (compensates up to0.5V wiring drop), global/local ON/OFF control, output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), current sharing (for parallel operation), auxiliary power output (5V/2A for base unit,5V/10mA per module)

6 EMC compliance: Emission meets EN55032 Class B; immunity meets EN61000-4 series (ESD, RF field, EFT/Burst, Surge, etc.); complies with SEMI F47

7 Compact and robust mechanical design: Dimensions 250x127x41mm, weight ~2kg; easy to mount with specified screws and torque

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical-grade power (complies with 2x MOPP standards)

2 Industrial automation: Ideal for PLCs, DCS systems, motor drives needing multiple DC outputs

3 Test and measurement instruments: Flexible output configuration for various test setups

4 Communication systems: Power for routers, switches, base stations requiring reliable, scalable DC power

5 Data centers: Redundant power solutions via parallel operation for servers or storage devices

6 Instrumentation: High-precision equipment needing stable, low-noise DC power

7 Any application requiring customizable, high-power DC outputs with safety and reliability

注意事项 PRECAUTIONS

1 Installation precautions:

2 Ensure proper grounding to prevent electric shock; use M4 screws with torque7-10 Kgf-cm (max penetration depth4mm)

3 Maintain proper ventilation as per airflow direction (specified in mechanical specs) to avoid overheating

4 Operation guidelines:

5 Global ON/OFF: Install the shorting connector (RC1 to GND-P) if not using global control (else no output)

6 Local ON/OFF: For NMS-240 modules, short RC2 to GND to turn off output; open to turn on. For NMD-240, short RC2/RC3 to GND1/GND2 to turn off respective outputs

7 Remote sense: Use twisted pairs for +S/-S lines to minimize noise; do not exceed0.5V compensation

8 Parallel operation:

9 Connect CS pins of all modules; ensure output voltage difference between modules <0.2V

10 Total output current ≤ sum of rated currents of modules; total power ≤1200W (NMP1K2)

11 Max6 modules in parallel (NMP1K2); use short, thick wires for parallel connections to reduce voltage drop

12 Disable PC (current programming) function when modules are in parallel

13 Derating requirements: When output voltage <12V and ambient temp is -15°C to -30°C, derate current to90% of rated; follow derating curves for ambient temps above50°C

14 Safety warnings:

15 Do not touch live parts when the unit is powered on; always disconnect input power before maintenance

16 Ensure input voltage matches the rated range (90-264VAC/120-370VDC) to avoid damage

17 Replace faulty modules only with compatible Meanwell NMS/NMD series modules

18 Maintenance tips:

19 Keep the unit clean and free of dust to maintain cooling efficiency

20 Periodically check for loose connections and damaged components; replace as needed
