Operating principle:

• When there is power on the grid, the cabinet will automatically switch to the operation of supplying DC power to the load through the rectifier at the same time with full charge of the battery, the DC source will be automatically stabilized thanks to the three-phase bridge rectifier. controlled by Thysistor.

• During a power outage, the DC power from the accumulator accumulates the load through directional circuits using diodes, ensuring that the switching and protection device system always operates safely and reliably. .
