产品特点 FEATURES

1 Modular design: NMP650 (4 slots, max 650W) and NMP1K2 (6 slots, max1200W) front-ends, compatible with single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240:30V/5A each, combined240W) modules

2 Wide input range:90~264VAC or120~370VDC, frequency47~63Hz

3 High efficiency:Up to91% (full load with H/K modules at24V/48V)

4 Multiple protection functions:Overload (constant current limiting/shut down), overvoltage (shut down, repower to recover), overtemperature (shut down, auto recover after temp drop)

5 Flexible control:Global/local ON/OFF (RC1/RC2/RC3 pins), remote sense (compensate up to0.5V drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), T-Alarm (overtemp warning), current sharing (parallel operation support)

6 Safety compliance:Meets EN60601-1 (medical), EN62368-1 (ITE), IEC standards; earth leakage current <400uA/264VAC

7 Auxiliary power:+5V-AUX_P (2A for NMP1K2,1.5A for NMP650), Vcc2 (5V/10mA for modules)

使用场景 APPLICATIONS

1 Industrial automation:Power supply for PLCs, DCS systems, robotic control units

2 Medical equipment:Compatible with medical devices (2x MOPP isolation) like diagnostic instruments, patient monitors

3 Telecom infrastructure:Power for base stations, optical transceivers, network switches

4 Test & measurement:Stable power for lab instruments, oscilloscopes, signal generators

5 Data centers:Modular power for server racks, storage systems

6 Industrial machinery:Power for CNC machines, packaging equipment, printing presses

注意事项 PRECAUTIONS

1 Derating requirements:When output voltage <12V and ambient temp is -15~-30°C, derate output current to90% of rated value; refer to derating curves for ambient temp and input voltage conditions

2 Installation:Ensure correct mounting torque (12Kgf-cm for AC terminal,10Kgf-cm for DC terminal); assemble shorting connector for RC1 to GND-P if global ON/OFF is not used

3 Parallel operation:Connect CS pins of modules, keep output voltage difference <0.2V; total power not exceed NMP650 (650W) or NMP1K2 (1200W) max; use short/large-diameter wiring; remote control must turn all parallel modules ON/OFF simultaneously

4 Remote sense:Use twisted pairs for +S/-S lines to minimize noise

5 Programming:Follow voltage ranges for PV (output voltage) and PC (current) programming; do not use PC function when modules are in parallel

6 Temperature management:Monitor T-Alarm signal (high=overtemp, low=normal) to prevent overheating

7 Safety:Ensure proper grounding; do not exceed rated current/power to avoid damage
