Thomson Digital Energy Series – TS9（B）

The bypass isolation type ATS is composed of a parallel combination of a pull-out main automatic transfer switch and a bypass isolation switch. Before the main automatic transfer switch is pulled out for maintenance, testing, and upkeep, the load can be powered by the bypass isolation switch first. Afterwards, when the main automatic transfer switch is pulled out for maintenance, testing, and upkeep, the operation process will not cause power outage to the load. The main automatic transfer switch includes standard transfer type, delayed transfer type, and parallel transfer type, suitable for data centers, airports, finance, high-tech industries, and other places where continuous power supply is still required for ATS testing, maintenance, and inspection.

The bypass switch module includes three basic positions:

Automatic position: The common side contact of the bypass is disconnected, and the spare side contact of the bypass is disconnected

Bypass - Common Side: The contact on the common side of the bypass is closed, and the contact on the spare side of the bypass is disconnected

Bypass standby side: The common side contact of the bypass is disconnected, and the standby side contact of the bypass is closed

When the bypass switch is closed, it can be easily removed and has 3 positions to choose from:

Connection position: The automatic transfer switch is connected to the main circuit, and the bypass switch is in the automatic position, which is the normal working position

Test location: The load is powered by the bypass switch, and the secondary circuit of the automatic transfer switch has power, but the main circuit is completely isolated from the load. ATS can perform transfer function testing through the test button without affecting the normal power supply of the load

Isolation position: The load is powered by a bypass switch, and the automatic transfer switch is completely isolated from the power circuit,

And it can be removed for easy on-site maintenance
