ZQ2G Dual power automatic switch

Product overview

• ZQ2G automatic transfer switch(ATSE) is a combination of switch and logic control, without additional controller. The automatic transfer switch that truly realizes electromechanical integration has the functions of voltage detection, frequency detection, communication interface, electrical and mechanical interlock, 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 is equipped with a switch spring to store energy and an instantaneous release acceleration mechanism, which can quickly connect and disconnect the circuit breaker or conduct circuit conversion to achieve safe isolation through obvious visible state, greatly improving various electrical and mechanical properties.
• Comply with IEC60947-6-1 ,GB/T 14048.11.

Structure overview

• The overall design of ZQ2G automatic transfer switch is metal shell,small and firm.ZQ2G automatic transfer switch, the control part is made of metal shell, and the switch part is made of glass fiber unsaturated polyester resin shell, which has strong dielectric property, protective ability and reliable operation safety.
• The switch is applicable to the automatic conversion of the main power supply and stand by powersupply of the power supply system or the automatic conversion and safety isolation of two load equipment.
• The switch is beautiful, novel, simple, small and functional, which is the best choice of similar products.
• ZQ2G automatic transfer switch series products have passed the electromagnetic compatibility test.
