11/8/2022 0 Comments Automatic transfer switch![]() ![]() Such load switching in operation, when the phase difference between the two power supplies is large, the motor will be subject to huge mechanical stress. Double-power automatic transfer switch generally is not allowed to changeover large motor or high inductive load. If the dual-power automatic transfer switch has the function of self-switching and self-replicating, when the main power supply resumes, the automatic transfer switch shall switch back to the main power supply after delay.Ģ. The following are some requirements of switching time for some electrical equipment for automatic transfer switch.ġ. However, some electrical equipment has strict requirements on the conversion time of the double-power automatic transfer switch, so the transfer time of the dual-power automatic switch selection must be considered. When the ATS switches to the standby power supply, there is a delay, which is mainly used in the conversion from the main power supply to the standby power supply. Tips: Transfer time of automatic transfer switch Indicate the working positions: I, 0, II. (When the padlock is locked, it cuts off power source of inner control circuit, thus ATS cannot be operated neither automatically or manually.) Special for inspection and repair, namely, first make the ATS in “0” position by the operating handle, pull the padlock to lock for security reasons, and then carry out the inspection and repair. #Automatic transfer switch full#When the electric lock is switched on, ATS can execute the full auto operation, remote control, and forcedly switching off “0” operation when electric lock is off, ATS can only be operated manually.īefore using the operating handle, please be sure to turn off the electric lock. Switch on/off the power source of control circuit in the ATS. Push “I” button, and normal power will be in service push “II” button, and backup power will be put into use push “0” button, and two loops of power supply will be cut off. ![]() Push “0” button forcedly, and ATS will cut off two loops of power supply. When normal power is off, the ATS will automatically transfer to standby power when normal power recovers, ATS will auto-transfer back to normal power. * For the specific functions of ATS controller mode, please check below: ![]()
