Static Power Switch iSTS

Static Transfer Switch (STS) or normally known as static switch operates in two separate switch between AC power supply. It provides your critical load or single cord (single supply), equipment with an alternative supply source, thus increasing and improving power reliability and availability.

The iSTS continuously monitors the supply sources and should the presently connected supply fail or degenerate or become useable, the critical load is automatically and transparently transferred to the alternate source.

This switching process is undertaken as a break before make transfer. The break in the supply transition is so short that it is not seen by the critical load. This is preferable to a make before break (or overlapping) changeover because when the two supplies are different and connected together large and unpredictable currents would flow between the sources degenerating both supplies and therefore the supply to the critical load.

In case of downstream fault the iSTS will not transfer the fault to the alternate supply even if the voltage is adversely affected. Once the fault current has cleared the iSTS will resume normal operation protecting the critical loads from voltage disturbance.
