The JHQS1 series PC level isolated dual power automatic transfer switch integrates switch and logic control, without the need for an external controller. The actual operation is managed by the logic control board through various logic commands to manage the operation of the motor and gearbox. The motor drives the switch spring storage JHQS1 switch, which is designed with a metal shell shape, compact and sturdy. The control part of the transfer switch is a metal shell, and the switch shell components are suitable for automatic transfer between the main power supply and the backup power supply of the power supply system, or automatic transfer and safety isolation of two load devices. The model and its meaning are realizing the automatic transfer switch of mechatronics integration, with functions such as voltage detection, frequency detection, communication interface, electrical and mechanical interlocking, and the possibility of instantaneous release acceleration mechanism. It can quickly connect and disconnect the circuit or perform circuit conversion, and achieve safety isolation through obvious visible states. It is made of glass fiber unsaturated polyester resin and has strong dielectric performance, protection ability, and reliable operational safety. The switch has a beautiful, novel, simple, small size, and comprehensive functions, making it an ideal choice for different occasions. Realize automatic, electric remote, and emergency manual control. Improved various electrical and mechanical performance.
