产品特点 FEATURES

1 Brand: MW (Meanwell), Model: NMP1K2-KKHECH-00, part of NMP series modular power supplies

2 Front-end capacity:1200W max,6 slots for output modules

3 Output module:NMS-240-K (single output), rated specs:48V DC,5A rated current,240W rated power; adjustable voltage range:30~55V; ripple & noise max:250mVp-p

4 Input parameters:Wide input voltage range (90~264VAC,120~370VDC), frequency range (47~63Hz), high power factor (PF>0.95 at230VAC full load; PF>0.98 at115VAC full load)

5 Efficiency:Up to91% (full case load with H/K modules at nominal24V/48V)

6 Safety compliance:Meets medical (2x MOPP between primary-secondary) and ITE standards (ANSI/AAMI ES60601-1 Ed3.1,UL62368-1,TUV EN60601-1 Ed3.1,EN62368-1,IEC60601-1 Ed3.1,IEC62368-1,EAC TP TC004)

7 Protection functions:Overload (constant current limiting), Overvoltage (shut down output, re-power to recover), Over-temperature (shut down output, auto-recover when cool)

8 Control functions:Remote ON/OFF (local for modules), remote sense (+S/-S to compensate voltage drop up to0.5V), output voltage programming (PV pin), current programming (PC pin), DC OK signal (TTL level for output status), current sharing (CS pin for parallel operation)

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

10 Mechanical specs:Front-end dimensions (250*127*41mm L*W*H), module dimensions (118.5*37.9*18mm L*W*H)

使用场景 APPLICATIONS

1 Medical equipment:Diagnostic devices, patient monitors, and other medical systems requiring compliant stable power

2 Industrial automation:PLCs, motor drives, sensors, and control panels in manufacturing lines

3 Telecommunications:Routers, switches, base stations, and communication infrastructure needing reliable DC power

4 Test & measurement:Laboratory instruments, testing setups requiring adjustable precise voltage outputs

5 Data centers:Server racks, storage systems, and network equipment needing high-capacity modular power

6 Embedded systems:Custom industrial devices and embedded applications with specific power requirements

注意事项 PRECAUTIONS

1 Installation:Use M4 screws for mounting (torque7~10 Kgf-cm); ensure proper air flow direction as per mechanical specs; keep vents unobstructed to prevent overheating

2 Operation:

3 Global ON/OFF:Default global ON requires shorting RC1 (CN32-PIN6) to GND-P (CN32-PIN3); open for global OFF

4 Local module control:Open RC2 (CN81-PIN3) to GND (CN81-PIN1/2) for module ON, short for OFF

5 Remote sense:Connect +S/-S pins to load terminals to compensate voltage drop (max0.5V)

6 Parallel operation:For multiple modules in parallel, connect CS pins; ensure output voltage difference <0.2V; total load not exceeding1200W; remote control must trigger all parallel modules simultaneously

7 Derating:For output voltage <12V and ambient temp -15~-30°C, derate output current to90% of rated; refer to official derating curves for other conditions

8 Protection handling:Over-temperature protection auto-recovers when internal temp cools down; overvoltage protection needs re-powering to recover; overload protection uses constant current limiting

9 Maintenance:Regularly clean dust from vents; inspect electrical connections for tightness and corrosion; avoid operating in humid or corrosive environments without proper protection
