Home > Product > Dedicated Drive

GD350-EP series is custom-developed based on the GD350 hardware platform. It is applicable in industries such as shaft generator, shore power supply, emergency power backup, soft motor starting, power/variable frequency switching, and voltage- and frequency-stabilized power sources. The product can be optionally equipped with a grid synchronization card, enabling quick synchronization and phase-locking between the grid power and backup power output.

Detail

1. Stable voltage and frequency output, no interference to other devices

The system employs closed-loop feedback control for output voltage regulation to ensure power stability. It comes standard with magnetic rings and offers optional filters to effectively prevent electromagnetic interference with other equipment in the system.

2. Parallel operation with synchronization and phase-locking

Grid power synchronization terminal card tracks the input voltage to keep the output voltage synchronized with the grid. The VFD input power phase sequence (positive/negative) can be viewed through function codes.

3. Reduced inrush current

The VFD can quickly switch to the backup power supply in the event of a grid power interruption or fluctuation. With inrush current maintained below rated current levels, it ensures continuous operation of critical equipment, thereby substantially improving overall power supply reliability.
