产品特点 FEATURES

Modular design with 6-slot chassis (NMP1K2) supporting up to 6 NMS-240 (single output) or NMD-240 (dual output) modules, enabling flexible configuration of output voltages (5V/12V/24V/48V) and currents

High power capacity of 1200W max, suitable for high-demand applications

Wide input voltage range: AC 90-264V or DC120-370VDC, adapting to various power grids

Comprehensive protection functions: Overvoltage (OVP), overcurrent (OCP), overtemperature (OTP), overload (OLP) protection; shutdown and auto-recovery or re-power on recovery based on protection type

Advanced control features: Global/local remote ON/OFF, output voltage programming (PV), current programming (PC), remote sense (compensates up to 0.5V voltage drop), current sharing for parallel module operation

Status monitoring: DC OK signal (TTL level) for output status, T-Alarm signal for overtemperature warning

Safety compliance: Meets medical (ANSI/AAMI ES60601-1 Ed3.1) and ITE (UL62368-1) standards; 2x MOPP isolation between primary and secondary

Efficient performance: High efficiency (up to 91% for specific modules), low leakage current (<=400uA @264VAC), good power factor (PF>0.95@230VAC full load)

Auxiliary power outputs: 5V/2A (NMP1K2) and 5V/10mA (module-level) for control circuits

使用场景 APPLICATIONS

Industrial automation systems: Power supply for PLCs, DCS, motor drives, sensors, and control panels

Medical equipment: Suitable for devices complying with medical safety standards (e.g., diagnostic instruments, patient monitors)

Test and measurement instruments: Provides stable, configurable power for lab tools like oscilloscopes, signal generators

Communication systems: Supports base stations, routers, switches, and network equipment needing multiple voltage outputs

Data centers: Modular power for server racks, storage systems, and backup units

Precision electronics manufacturing: Power for semiconductor equipment, LED production lines

Industrial control: Used in factory automation lines, robotic systems, and process control devices

注意事项 PRECAUTIONS

Installation: Ensure proper ventilation (follow airflow direction), use recommended M4 screws with 7-10 Kgf-cm torque; avoid blocking vents

Wiring: Strictly follow pin assignments (e.g., RC1 to GND-P for global ON/OFF); use appropriate wire gauge to minimize voltage drop

Derating: When output voltage <12V and ambient temp -15°C to -30°C, derate current to 90% of rated; follow derating curves for temp and input voltage

Shorting connectors: Install the RC1-GND-P shorting connector if not using external global ON/OFF control; missing connector may cause no output

Parallel operation: Connect CS pins of modules together; ensure output voltage difference <0.2V; do not exceed 6 slots (NMP1K2); avoid PC function in parallel mode

Remote sense: Use twisted pairs for sense lines; do not exceed 0.5V compensation limit

Temperature management: Operate within -30°C to +70°C ambient temp; monitor T-Alarm signal for overtemperature

Safety: Disconnect power before maintenance; ensure proper grounding; do not exceed rated power/current for modules
