CZQ8 series dual power automatic transfer switch

Product overview:

CZQ8 series dual power automatic transfer switch is an automatic transfer switch that integrates switch and logic control, and truly realizes electromechanical integration. It has the functions of voltage detection, frequency detection, communication interface, electrical and mechanical interlocking, and can realize automatic, electric remote, and emergency manual control. The operation is realized by the logic control board to manage the operation of the motor and gearbox with various logic commands. The motor drives the switch spring to store energy and the instantaneous release acceleration mechanism to quickly connect the breaking circuit or perform circuit conversion. Safe isolation is achieved through the obvious visible state, which greatly improves the electrical and mechanical performance.
