It will increase the transfer speed and improve the switching life, ensure the power continuity for important load. It can ensure the normal operation of equipment, increase the service life and efficiency.

The solid state transfer switch applies to double power supply lines. When the main power becomes interrupted and abnormal, the important load will be transferred to spare power which will ensure the reliability of power supply.
