产品特点 FEATURES

Modular design: NMP1K2 model offers 6 slots for flexible configuration with single (NMS-240) or dual (NMD-240) output modules, supporting up to 1200W total power.

Wide input range: 90~264VAC or 120~370VDC, compatible with global power grids.

High efficiency: Up to 91% efficiency at full load (for H/K modules at 24V/48V nominal voltage), reducing energy loss.

Multiple output options: Single output modules (5V/36A,12V/20A,24V/10A,48V/5A) and dual output modules (30V/5A each), with adjustable voltage ranges (e.g.,5V module:3~6V,12V module:6~15V).

Comprehensive protection: Overload (constant current limiting), overvoltage (shut down and recover on repower), overtemperature (automatic recovery after cooling) protections.

Remote monitoring and control: Supports remote sense (compensate voltage drop up to 0.5V), DC OK signal (TTL level indicating output status), remote ON/OFF (via dry contact), and current sharing for parallel operation.

Safety compliance: Meets medical (ANSI/AAMI ES60601-1 Ed.3.1) and ITE (UL62368-1) standards, with 2x MOPP isolation between primary and secondary.

Auxiliary power: 5V/2A auxiliary output for control circuits, and 5V/10mA per module for local control.

注意事项 PRECAUTIONS

Derating requirements: When output voltage is below 12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value; refer to derating curves for load and temperature adjustments.

Mounting instructions: Use M4 screws with recommended torque (7~10 Kgf-cm), ensure proper airflow direction as per mechanical specs, and avoid blocking ventilation.

Parallel operation: When paralleling modules, connect CS pins together, ensure output voltage difference <0.2V, total power not exceeding 1200W for NMP1K2, and use short, thick wires for load connections.

ON/OFF control: If global ON/OFF control is not used, assemble the provided shorting connector (RC1 to GND-P) to enable output; local control via RC2/RC3 pins requires proper dry contact wiring.

Remote sense: Connect +S/-S pins to load terminals to compensate for voltage drop in wiring (up to 0.5V).

Safety precautions: Do not modify the unit or use non-compliant accessories; avoid operating beyond rated parameters to prevent damage or safety hazards.

Temperature monitoring: Utilize T-Alarm signal to monitor internal temperature and take action if the alarm is triggered (high signal indicates over-temperature).
