PC Type Load Auto Transfer Switch for Generators It adopted double complex contact/ horizontal pulling mechanism/micro motor energy pre storage and micro-computer control technology, basically come to Zero arc ( no arcing chamber); Adopted reliable mechanical interlock and electric interlock, executive unit adopt independent load disconnect switch, it makes more reliable and safety; Adopt "Zero Position" technology, it can force to set to Zero Position under emergency situation ( cutoff two way power supply, meet the fire linkage requirements; Load disconnect switch change over adopt singleness motor drive, switch over smooth and reliable, no noise, little impact; The driving motor have instant current across only under the load disconnect switch change over, stable working status no need to provide the working current, outstanding energy saving. Executive load disconnect switch have mechanical interlock, make sure the Normal power and Reserve Power working reliable and no interference; Distinct ON and OFF position indicator, padlock function etc., make reliable and safe isolation between power supply and loading. High security, high automatization, high reliability, working life more than 8000 times; Electromechanical integration design, accuracy change over, flexible, smoothly, adopt international advanced logical control technology, high anti-interference ability, no interference outward. Have main power ON, backup power OFF; main power OFF, backup power ON; main and backup power OFF; three working mode (I-o-II); Easy installation, control circuit adopt plug type terminal connection Four operating functions: Emergency manual, motor remote control, emergency OFF under auto control status, auto control operation. Basic Type Switch Control Characteristic Suitable for two way main and backup power system, auto transfer with auto recovery; Can expand functions by outer connection; Auto, Remote, Manual control functions; Delay 0.5s signal detect, avoid miss actuation; Under Auto control status have "O" position remote control; Can with RS-485 communication port ( optional), according to customer required.
