Product Introduction

NHDAG series power frequency inverter power supplyIt is a fourth generation power frequency intelligent dedicated inverter power supply developed with new digital technology to meet the high reliability requirements of the power system for power sources. By adopting SPWM pulse width modulation technology, IGBT power module, and output isolation transformer, the output of the inverter power supply is a pure sine wave power supply with stable frequency and voltage, noise filtering, no interference from power grid fluctuations, and low distortion. It has the characteristics of strong load capacity, good load compatibility, and wide DC input voltage range, greatly meeting the needs of various electrical environments.

Widely used in substations, hydropower stations, railways, office automation, industrial production, military research and other fields.

　　The inverter power supply can choose from three working modes (to be determined when ordering):

　　Pure DC power supply type:Pure DC input, the inverter power supply shuts down and stops working after DC power failure.

　　DC main supply type:DC and AC dual input, DC priority power supply, AC backup; Automatically switch to AC power supply after DC power failure.

　　Exchange main supply type:DC and AC dual input, AC priority power supply, DC backup; Automatically switch to DC power supply after AC power outage.

Main Features

☆ Adopting SPWM pulse width modulation technology, IGBT power module, and output isolation transformer.

Humanized LED indicator light/LCD interface design.

☆ Automatic bypass conversion to achieve uninterrupted load operation. (Optional)

☆ Standard RS232 communication interface. (Optional)

☆ Protection against reverse connection, undervoltage, overvoltage, overload, short circuit, etc.
