Product Description


GLD automtic change-over switch (ATSE) integrates switch and logic control. Thus it is not necessary to provide external controller. This truly electrome chemically integrated automatic change-over switch has the following functions, such as voltage detection, frequency detection,communication inferface, electrical and mechanical interlocking etc. So automatic control, electrical remote control and emergency manual control can be performed.

The operation is carried out through the logic control board, which gives various commands to control the motor and gear-box. The motor drives the accelerator which can take Switch-spring power accumulating and instantaneous released, Thereby quickly turning on the breaking circuit or circuit conversion, through the visible state to achieve security isolation,and extremely increasing the various electrical and mechanical performance.

The shell of switch is made of metal, being small and compact, While the shell of switch GLD is made of different materials: Its control section is made of metal, but the switching section is made of glassfibre unsaturated polyester resin, having stronger dielectric and protective capability as well as safe operation performance

The kind of switch is suitable for the automatic change-over of the main power source and the
Secondary power supply system or the automatic change-over and safe separation of the 2 sets
of load-equipment. This kind of switch has beautiful, novel and simple structure, a small volume
But complete functions, being the best choice among congener of products.
