Structure and working principle
structure
The FSQ3 dual power switch mainly consists of two miniature circuit breakers, motors, controllers, and mechanical rotating devices. The switch has three states and positions for users to choose from. Commonly used power supply
Double split, backup power supply on.
◆ Adopting high breaking miniature circuit breakers with circuit breaker breaking capacity and characteristics.
◆ It has the advantages of simple and practical structure, convenient operation, no noise, low impact force, and long service life.
operational principle
The dual power automatic transfer switch detects two power sources through the controller. When one power source is abnormal, the controller makes a logical judgment on the detection result and drives it according to the controller's instructions
The operating mechanism opens or closes to ensure safe and reliable power supply to the load.
