Tips: What's dual power automatic transfer switch?

The automatic transfer switch (ATS) is a switch to transfer between two power sources. It is constituted by one or several change-over switching equipment and other necessary apparatuses. It is used to detect the power circuit. In addition, it changes over one or several load circuits from one power supply to the other power supply.

For the use of dual power automatic transfer switch, briefly, it is connected with one utility power and one backup power. When the utility power suddenly fails, it will be transfer to the backup power supply automatically through the ATS (at the small load, the backup power supply can be supplied by the generator) to enable the equipment to operate normally. The most common application is the elevator, fire protection and monitoring. The condition is the same to the UPS uninterruptible power supply of the bank. However, its backup is the battery set. It is used in some factories and mines or units with loads of class I category and class II category.

In this video, it will show how ATO 4-pole automatic transfer switch changeover between the mains and standby power supplies in the manual & auto mode.

ATO.com have a wide range of selections with ratings from 6 amps to 800 amps. ATS transfer switch is a device to changeover between the utility and standby power source when one power fails. In this video, ATO will show you disassembly of automatic transfer switch.

4-pole Automatic Transfer Switch for Emergency Power Supply

When the main power is cut off, the ATS can automatically switch to the backup generator power supply. Suitable for schools, hospitals, homes and other occasions.
