产品特点 FEATURES

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

2 Wide input voltage range: 90~264VAC or 120~370VDC, adaptable to various power grids.

3 High efficiency up to 91% (typical) at full load with H/K modules (24V/48V nominal), reducing energy loss.

4 Compliance with multiple safety standards: Medical (2x MOPP between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, etc.), suitable for medical and industrial applications.

5 Rich protection features: Overload (constant current limiting), overvoltage (shut down and recover on re-power), overtemperature (shut down and auto-recover when cool), ensuring device safety.

6 Flexible control options: Global ON/OFF (via RC1 and GND-P) and local ON/OFF (via RC2/RC3 and GND) for individual modules, remote sense (compensates up to 0.5V voltage drop), output voltage/current programming (PV/PC pins).

7 Current sharing capability for parallel operation of NMS-240 modules, ensuring balanced load distribution (output voltage difference <0.2V required).

8 DC OK signal (TTL level) indicating module output status, and T-Alarm signal for overtemperature warning.

9 Auxiliary power outputs: 5V/2A (NMP1K2) for front-end, and 5V/10mA for each NMS-240 module, supporting external control circuits.

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety compliance (2x MOPP), like patient monitors, diagnostic instruments, and medical imaging systems.

2 Industrial automation: Used in PLCs, DCS systems, and robotic control units, leveraging modularity to meet varying power needs.

3 Test and measurement instruments: Provides stable and adjustable power for lab equipment, signal generators, and oscilloscopes.

4 Communication systems: Powers base stations, routers, and network switches, with wide input range and high efficiency ensuring reliable operation.

5 Data centers: Supports server racks and storage systems, using parallel operation for scalable power capacity.

6 Industrial control systems: Used in factory automation lines, process control equipment, and power distribution units.

注意事项 PRECAUTIONS

1 Ensure the shorting connector (from RC1 to GND-P) is properly assembled; otherwise, the unit will have no output.

2 For remote sense function, connect +S and -S pins to the load terminals to compensate for voltage drop on wiring (max 0.5V).

3 When programming output voltage (PV) or current (PC), refer to the spec sheet's guidelines for external voltage ranges and connections.

4 For parallel operation of NMS-240 modules: Connect CS pins mutually, ensure output voltage difference <0.2V, and do not exceed total output power (1200W for NMP1K2).

5 Follow the derating curve: Derate output current to 90% of rated value when ambient temperature is -15~-30°C and output voltage <12V; derate as per ambient temperature and input voltage.

6 Adhere to mounting torque specifications: 12Kgf-cm for AC input terminals, 10Kgf-cm for DC output terminals, and 7~10Kgf-cm for mounting screws.

7 Keep the device within the operating ambient temperature range (-30~+70°C) and avoid condensation or dust accumulation.

8 Do not use output current programming (PC) function when modules are in parallel operation.
