CDUGD voltage regulator cabinet
A Dynamic Voltage Restorer (DVR) is an advanced power electronic device. This device utilizes advanced power electronics semiconductor technology and control technology, combining the two to ensure user power safety. Using internationally leading DSP/FPGA/CPLD control chips, the DVR monitors power voltage quality in real time. When a voltage sag or surge is detected, the regulator instantly switches the power supply of the backend equipment to the inverter, ensuring that the sensitive equipment on the backend remains unaffected. The control and shutdown of the dynamic voltage restorer are software-controlled, and its typical switching time can be controlled within 1 millisecond, guaranteeing uninterrupted power supply.
