Yangzhou Keyu Electrical Co.,Ltd.

YKYQ1 series automatic transfer switches integrate switches and logic circuit together without controller. They really achieve mechatrcnics with functions like Communication interface, electric and mechanic interlock. The switches apply to the automatic change of the main source and reserve power supply of power supply system, reversing operation of electric motors and multiple use of E-Machine with one reservation control, the automatic control and security isolation of two circuit load equipment. They adopt double—combined contacts, pulled type and Switch off mechanism，micro-machine pre-accumulated energy and micro-control technology and they basically achieve zero flashover without arcing shield . They can reset in emergency with crossover zero point technology and cut off Complete power system at the same time. They have padlock and can display the on/off state as well as segregate power source from load easily. Their Electromagnetic Compatibility, strong antijamming capability, Zero-Impact, High automation degree, Multiple Access input/output interfaces which make PLC remote control and automation of the system easier.
