产品特点 FEATURES

1 Modular power supply with 6 slots (NMP1K2 series), total maximum power 1200W; each slot supports NMS-240 single output modules (up to 240W) or NMD-240 dual output modules

2 Wide input range: 90~264VAC (47~63Hz) or 120~370VDC, suitable for global applications

3 High energy efficiency: Up to 91% typical at full load (for H/K modules at 24V/48V nominal voltage); high power factor (PF>0.95 at 230VAC full load, PF>0.98 at 115VAC full load)

4 Multi-standard compliance: Meets ITE safety standards (UL62368-1, EN62368-1) and medical safety standards (2x MOPP between primary and secondary), suitable for industrial and medical-related applications

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shutdown, re-power to recover), overtemperature (shutdown, auto-recover after cooling), short circuit (hiccup mode or constant current limiting for specific modules)

6 Rich functional features: Remote sense (compensate up to 0.5V voltage drop on load wiring), remote ON/OFF (global and local control), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (TTL level indicating module status), current sharing (for parallel operation of modules), auxiliary power outputs (5V-AUX-P:2A, Vcc2:5V/10mA)

7 Wide operating temperature range: -30~+70°C (with derating as per specifications for low/high temperatures)

8 EMC compliance: EN55032 Class B (emission), EN61000-4 series (immunity including ESD, surge, EFT), ensuring stable operation in electromagnetic environments

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control systems in manufacturing lines

2 Medical equipment: Suitable for non-patient contact medical devices like diagnostic instruments, lab analyzers, and medical test equipment (complying with medical safety standards)

3 Telecommunications: Providing reliable power for network switches, routers, communication modules, and base station peripherals

4 Test and measurement: Used in lab test setups, electronic measurement equipment, and prototype development requiring adjustable and stable power

5 Broadcast systems: Powering broadcast gear such as video encoders, transmitters, and studio equipment

6 Data centers: Supplementary power for server racks, storage devices, or peripheral network equipment

7 Industrial control panels: Integrated into control panels for machinery and equipment requiring modular power distribution

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding of the unit; use recommended screws (M4 for front-end, M3.5 for modules) with specified torque (7~10 Kgf-cm for front-end mounting, 10 Kgf-cm for module terminals) to avoid loose connections

2 Operating conditions: Follow derating guidelines—reduce output current to 90% of rated value if output voltage <12V and ambient temperature is between -30~-15°C; derate output power as per temperature curves for ambient temps above 50°C

3 Global ON/OFF control: If not using global control, install the provided shorting connector (RC1 to GND-P) to enable output; otherwise, the unit will have no output

4 Parallel operation: When parallelizing modules for current sharing, connect CS pins of all modules; ensure total output power does not exceed 1200W; use short, large-diameter wires for parallel connections; do not use the output current programming (PC) function in parallel mode; remote control must turn all parallel modules on/off simultaneously

5 Safety: Do not touch live parts when the unit is powered on; ensure input voltage matches the rated range; do not exceed the maximum current/power limits of individual modules

6 Maintenance: Disconnect the power supply before performing any maintenance or servicing; keep the unit clean and free of dust to prevent overheating and ensure optimal performance

7 Wiring: Use appropriate wire gauge for input/output connections to minimize voltage drop; for remote sense functionality, correctly connect +S/-S pins to the load terminals to compensate for wiring losses
