产品特点 FEATURES

1 Modular architecture: NMP1K2 model supports up to6 slots for output modules, each module (NMS-240 single output or NMD-240 dual output) delivers up to240W; compatible with modules of5V(C),12V(E),24V(H),48V(K) and dual output types

2 Wide input compatibility: Accepts90-264VAC (50/60Hz) or120-370VDC input, suitable for global use

3 High energy efficiency: Typical efficiency up to91% (when using H/K modules at24V/48V nominal voltage full load), reducing energy loss and heat generation

4 Advanced power factor correction: PF>0.95 at230VAC full load, PF>0.98 at115VAC full load, minimizing harmonic distortion and improving grid compatibility

5 Multi-standard safety compliance: Meets medical safety standards (2x MOPP isolation between primary and secondary circuits) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, EN62368-1 etc.), ensuring safe operation in various applications

6 Comprehensive protection mechanisms: Includes overload (constant current limiting), overvoltage (shut down output, recover via re-power), overtemperature (auto shut down when overheated, recover when cooled) protections; earth leakage current <400uA at264VAC, touch current <100uA at264VAC

7 Flexible control functions: Supports global (entire unit) or local (per module) ON/OFF control; remote sense (compensates up to0.5V wiring drop); output voltage (PV pin) and current (PC pin) programming; DC OK signal (TTL level indicating module output status); current sharing for parallel modules (balance current distribution)

8 Auxiliary power supply: Front-end provides5V/2A auxiliary power; each NMS-240 module provides5V/10mA auxiliary power (Vcc2 pin)

9 Compact mechanical design: Dimensions250x127x41mm (LxWxH), lightweight (~2kg), easy to integrate into various systems

使用场景 APPLICATIONS

1 Medical equipment: Suitable for diagnostic devices (ultrasound, blood cell analyzers), patient monitors, and medical imaging systems—thanks to medical safety compliance (2x MOPP) and stable modular power

2 Industrial automation: Ideal for PLCs, industrial robots, control panels, and sensor networks—supports multiple voltage outputs (5V/12V/24V/48V) to power diverse components

3 Test and measurement instruments: Used in lab equipment (oscilloscopes, signal generators) that require precise, adjustable voltage/current outputs and reliable power

4 Communication infrastructure: Power supply for routers, switches, base stations, and fiber optic transceivers—wide input range and high reliability meet the demands of communication systems

5 LED lighting systems: Powers high-power LED arrays (like street lights, industrial lighting) that need24V/48V stable current and efficient power conversion

6 Data center and server peripherals: Modular power for distributed systems, server accessories, and storage devices—flexible slot design allows customization based on power needs

注意事项 PRECAUTIONS

1 Installation: Use M4 screws for mounting, torque within7-10 Kgf-cm; ensure proper airflow direction (as per mechanical diagram) to prevent overheating

2 Wiring: For remote sense function, use twisted-pair cables; for parallel module operation, use short, large-diameter wires to minimize voltage drop; strictly follow pin assignments for input/output terminals to avoid damage

3 Temperature derating: When output voltage <12V and ambient temperature ranges from-15°C to-30°C, derate output current to90% of rated value; refer to derating curves for different ambient temperatures and input voltages to ensure safe operation

4 Parallel operation: Max6 modules for NMP1K2; ensure output voltage difference between parallel modules <0.2V; total power should not exceed1200W; remote control must turn all parallel modules ON/OFF simultaneously; avoid using output current programming (PC pin) in parallel mode

5 Global ON/OFF control: If global control is not used, install the shorting connector (RC1 pin6 to GND-P pin3) to enable output—without it, the unit will have no output

6 Environmental conditions: Operate within-30°C to+70°C (with derating) and20-90% RH non-condensing; avoid exposure to moisture, dust, or corrosive gases to prolong service life

7 Protection handling: In case of overvoltage/overtemperature protection triggering, power off the unit, check the load and environment, then re-power to recover; for overload, reduce the load to within rated limits

8 Safety: Ensure proper grounding to minimize leakage current; do not touch live parts when the unit is powered on; follow all safety standards during installation and maintenance
