产品特点 FEATURES

Modular power supply with 6 slots, supporting up to 1200W total output power

Each slot compatible with NMS-240 (single output) or NMD-240 (dual output) modules (max 240W per module)

Wide input voltage range: 90~264VAC /120~370VDC

High efficiency: Up to 91% (at full load with H/K modules 24V/48V)

Compliance with multiple safety standards: IEC60601-1 (medical 2x MOPP), IEC62368-1, UL62368-1, TUV EN60601-1

Comprehensive protection: Overload (constant current limiting), overvoltage (shut down and recover on re-power), overtemperature (automatic recovery after cooling)

Flexible control functions: Global/local ON/OFF, remote sense (compensates up to 0.5V voltage drop), output voltage/current programming

Current sharing capability for parallel operation (up to 6 modules) to balance load

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

Auxiliary power outputs: 5V/2A (front-end),5V/10mA (per module)

Supports various output voltages:5V,12V,24V,48V (single output) or dual 30V (max 240W combined)

使用场景 APPLICATIONS

Industrial automation systems requiring multiple independent voltage outputs

Medical equipment (compatible with medical safety standards)

Test and measurement instruments needing flexible power configurations

Data centers and communication systems for reliable modular power supply

Embedded systems with varying power requirements

High-power applications using parallel operation (e.g., server farms, industrial machinery)

Research and development setups for prototyping with different voltage/current needs

注意事项 PRECAUTIONS

Ensure the shorting connector is installed for global ON/OFF control if not using external control signals

For remote sense function, use twisted-pair cables for +S/-S lines to reduce noise interference

When programming output voltage/current, reference signals to corresponding GND pins and follow specified ranges

In parallel operation: Output voltage difference between modules <0.2V; total power ≤1200W; max 6 modules

For ambient temperatures below -15°C and output voltage <12V, derate output current to 90% of rated value

Use compatible mating connectors (e.g., HRS DF11 series) for control and power pins

Overtemperature alarm: T-Alarm signal (TTL high) indicates internal temperature exceeds limits

Local module ON/OFF: Open RC2/RC3 to turn on, short to GND to turn off

Auxiliary power: Front-end provides5V/2A; modules provide5V/10mA for control circuits
