产品特点 FEATURES

1 Modular design: NMP1K2 model has 6 slots, supports single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240:30V/5A each) modules for flexible configuration

2 High efficiency: Up to 91% at full load with H/K modules (24V/48V nominal voltage), energy-saving

3 Safety compliance: Meets medical (2x MOPP isolation between primary and secondary) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, etc.)

4 Comprehensive protection: Overload (constant current limiting), overvoltage (shutdown, repower to recover), overtemperature (auto-recover after cooling) protection

5 Remote control & monitoring: Supports global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), DC OK signal (TTL level for output status), T-Alarm (overtemperature alert)

6 Current sharing: Allows parallel operation of NMS-240 modules for higher current output, with CS pin connection to balance current

7 Wide input range: 90~264VAC /120~370VDC, adaptable to different power grids

8 Auxiliary power: Provides 5V/2A (NMP1K2) auxiliary output for control circuits and 5V/10mA per module for local functions

使用场景 APPLICATIONS

1 Medical equipment: Suitable for diagnostic instruments, patient monitors requiring medical safety standards (2x MOPP isolation)

2 Industrial automation: Power supply for PLCs, DCS systems, servo drives and industrial control equipment

3 Test & measurement: Used in lab instruments (oscilloscopes, signal generators) needing precise outputs and remote monitoring

4 Telecom & data communication: Power for network switches, routers with multiple voltage needs

5 Industrial instrumentation: Supports sensors, transmitters in process control systems

6 Custom equipment: Ideal for devices needing configurable output voltages/currents via modular design

注意事项 PRECAUTIONS

1 Installation: Use M4 screws (torque7~10Kgf-cm, max penetration depth4mm), ensure proper ventilation as per airflow direction

2 Derating: When output voltage <12V and ambient temp is -15~-30℃, derate current to90% of rated value; follow derating curves for high temps

3 Remote sense: Use twisted pairs for +S/-S lines to minimize noise; secure connections to avoid voltage errors

4 Parallel operation: For NMS-240 modules, connect CS pins together, keep output voltage difference <0.2V; total power ≤1200W (NMP1K2); do not use PC function in parallel

5 ON/OFF control: Short RC1 to GND-P (CN32) for global ON; open RC2 (module pin) for local ON (short to OFF); assemble shorting connector if global control not used

6 Protection recovery: For overvoltage, repower unit to recover; overload uses constant current limiting (hiccup mode for some modules)

7 Wiring: Use appropriate wire gauge; for parallel modules, use short/large-diameter wires for current balance
