Description
【Working Principle】The power transfer switch is a complete set of two miniature circuit breakers, a motor and a mechanical rotating device, and the two power sources are detected by the controller..【Safe Power Supply】When the circuit is abnormal, the controller makes a logical judgment on the detection result, and drives the operating mechanism to open or close according to the controller's instructions, so as to ensure safe and reliable power supply to the load..【Applicable System】This dual power automatic transfer switch appliance is suitable for dual-circuit power supply systems with AC 50Hz or 60Hz, rated working voltage 400V, rated working current 63A and below..【 Function】This auto transfer switch has short-circuit, overload, under-voltage, and voltage-loss functions, and also has fire , double-opening, and output closing functions..【Applicable Buildings】This automatic power switch has a reasonable structure and can selectively switch between two power sources according to needs, especially suitable for office buildings that require fire .
