产品特点 FEATURES

1 Modular design: 6-slot chassis supporting up to six NMS-240 single-output modules (240W each), total maximum power of 1200W.

2 Wide input compatibility: Accepts 90-264VAC or 120-370VDC input voltage, 47-63Hz frequency range.

3 High energy efficiency: Achieves up to 91% efficiency at full load when using H (24V) or K (48V) modules at nominal voltage.

4 Comprehensive safety compliance: Meets medical safety standards (2x MOPP isolation between primary and secondary circuits) and ITE standards including ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, and IEC 62368-1.

5 Multiple protection mechanisms: Overload protection (shuts down output, requires re-powering to recover), overvoltage protection (constant current limiting), and overtemperature protection (shuts down output, automatically recovers when temperature decreases).

6 Adjustable output voltage: Each NMS-240 module offers voltage adjustment (e.g.,5V module:3-6V,12V module:6-15V,24V module:15-30V,48V module:30-55V) to suit diverse application needs.

7 Remote management capabilities: Supports remote sense (compensates up to 0.5V voltage drop on load wiring), remote ON/OFF control (local for individual modules, global for the entire unit), DC OK signal (TTL level indicating output status), current sharing (for parallel module operation), and output voltage/current programming via PV/PC pins.

8 Auxiliary power supply: Provides a global 5V/2A auxiliary output and a 5V/10mA auxiliary output per module for external control circuits.

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, DCS, servo drives, and sensor networks requiring stable, modular power distribution.

2 Medical equipment: Suitable for devices like patient monitors, diagnostic instruments, and laboratory equipment due to compliance with medical safety standards.

3 Telecommunication infrastructure: Supporting base stations, network switches, and routers that need reliable, scalable power.

4 Test and measurement devices: Powering precision instruments such as oscilloscopes, signal generators, and load testers that demand adjustable and stable voltage outputs.

5 Data center applications: Providing modular power to server racks, storage systems, and network devices where scalability and efficiency are key.

6 Industrial control panels: Used in manufacturing lines to power various control components with different voltage requirements.

注意事项 PRECAUTIONS

1 Installation requirements: Use M4 screws for mounting with a torque of7-10 Kgf-cm; ensure proper grounding to meet safety standards.

2 Derating guidelines: Follow the derating curve—reduce output current to90% of rated value if the output voltage is below12V and ambient temperature is between-15°C and-30°C; derate load as ambient temperature increases beyond50°C.

3 Wiring practices: Use20-26AWG wires for control pins; use short, large-diameter wires for parallel module connections to minimize voltage drop and ensure current sharing.

4 Parallel operation: When paralleling modules, connect the CS pins of all modules together; ensure the output voltage difference between modules is less than0.2V; do not exceed the total unit power of1200W.

5 ON/OFF control: Install the shorting connector (RC1 to GND-P) if global ON/OFF control is not used; use local RC2 pin (open for ON, short for OFF) to control individual module outputs.

6 Protection handling: In case of overload or overvoltage, re-power the unit to recover; for overtemperature, allow the unit to cool down before reusing.

7 Environmental conditions: Operate within the ambient temperature range of-30°C to+70°C (with derating above50°C) and humidity range of20-90% RH non-condensing.
