产品特点 FEATURES

Modular architecture: NMP1K2 (6 slots, max1200W) and NMP650 (4 slots, max650W) front-ends, compatible with single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240: two 30V/5A) modules.

Wide input compatibility: 90-264VAC (47-63Hz) or120-370VDC, with PF>0.95@230VAC full load.

High efficiency: Up to91% (for H/K modules at 24V/48V full load), reducing energy loss.

Safety certifications: Complies with ITE (UL62368-1, EN62368-1) and medical (ANSI/AAMI ES60601-1 Ed3.1, EN60601-1 Ed3.1) standards, with 2x MOPP isolation between primary and secondary.

Comprehensive protection: Overload (constant current limiting), overvoltage (shutdown, re-power recover), overtemperature (auto-recover after cooling).

Flexible control: Global (RC1 pin) or local (module RC2/RC3 pins) ON/OFF; remote sense (+S/-S) to compensate wiring voltage drop up to0.5V; PV (voltage programming) and PC (current programming) for adjustable output.

Parallel operation: Supports current sharing via CS pins for parallel modules, enabling higher power output (max6 modules for NMP1K2,4 for NMP650).

Status monitoring: DC OK signal (TTL level) indicates module output status; T-Alarm signal alerts over temperature.

Auxiliary power: Front-end provides5V/2A (NMP1K2) or1.5A (NMP650); modules offer5V/10mA Vcc2.

使用场景 APPLICATIONS

Industrial automation: Powering PLCs, DCS systems, servo drives, and field sensors in manufacturing lines.

Medical devices: Suitable for low-risk medical equipment like patient monitors, blood pressure meters, and lab analyzers (due to 2x MOPP isolation).

Telecommunications: Back-up power for routers, switches, and small base stations in telecom networks.

Test & measurement: Lab environments needing precise, adjustable DC power for component testing or prototype development.

Data centers: Modular power supply for edge computing servers or storage arrays requiring scalable power.

Renewable energy: Integration with solar inverters or wind turbines (supports DC input) to power control systems.

Broadcast equipment: Powering cameras, mixers, and transmission devices in TV or radio studios.

注意事项 PRECAUTIONS

Installation: Use M4 screws (torque7-10Kgf-cm) for front-end mounting; M3.5 screws (torque10Kgf-cm) for modules. Ensure proper grounding via FG pins.

Temperature derating: For ambient temperatures above50°C, reduce output power as per the derating curve; for output voltage <12V and ambient temp between-15°C and-30°C, derate current to90% of rated value.

Global ON/OFF setup: If not using global control, connect RC1 (CN32 pin6) to GND-P (CN32 pin3) with the included shorting connector to enable output.

Parallel operation: When paralleling modules, connect CS pins together; ensure output voltage difference between modules is <0.2V; total power must not exceed front-end max (1200W for NMP1K2,650W for NMP650). Avoid using PC function in parallel mode.

Remote sense: Use twisted-pair cables for +S/-S lines to minimize electromagnetic interference; compensate up to0.5V drop.

Programming: PV (voltage) and PC (current) pins are referenced to module GND; follow specified external voltage ranges to avoid damage.

Protection handling: Overtemperature protection auto-recovers when cooled; overvoltage/overload protection requires re-powering the unit to reset.

Slot management: Fill empty slots with BLANK-NMS240 covers to maintain proper airflow and prevent dust accumulation.

Wiring: Use appropriate gauge wires for input/output to handle current without overheating; follow pin assignments strictly.
