LD Automatic change-over switch (ATSE) integrates switch and logic control, thus 

it is not necessary to provide external controller. This truly electromechanically 

integrated automatic change-over switch has such functions as voltage detection,

frequency detection, communication interface, and electrical and mechanical

interlocking so that 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 release, 

swiftly turns making and breaking the circuit or makes circuit switching. The 

visible operation status can help you to perform safe separation, increasing 

extremely the various electrical and mechanical performances.



The shell of switch LD1 is made of metal, being small and compact while the shell

of switch LD is made of different materials: its control section is made of metal, 

but the switching section is made of glassfiber unsaturated polyester resin, 

having stronger dielectric property and protective capability as well as safe 

operation performance. 



This kind of switch is suitable for the automatic changeover of the main power 

source and the secondary power source of the power supply system or the 

automatic changeover and safe separation of the 2 sets of load equipment. 

LD series had been already passed the detection of EMC.
