Automatic transfer switches (ATS)


ATS Panel  is automatically transfers switch between main powers and spare powers, with purpose of maintain electric system is always ready in case main power is lost. Spare power can be generators, secondary transformers or UPS.

Opening ATS Panel can control upto from 3 to 4 power…. It can control switchgear for priority or non-priority load, it depents on requirement and purpose for its use. The most popular panel that we used is: 3 ACB, 3MCCB, 3 MC to control for priority or non-priority load with one main power and one spare power to supply power for it. That is ATS Coupling.
