Static Transfer Switches
The static transfer switch (STS) is an electrical device that allows an instantaneous transfer between power sources to the load. This superior switching time means that if one power source fails, the STS automatically switches to another back up power source quickly, so that the load will never recognize that a transfer was initiated. This device can be used to increase reliability of power for medical equipment or in data centers.Unlike traditional automatic transfer switches (ATS), a static transfer switch provides a fast load transfer (typically 1/4 of a cycle), which ensures uninterrupted operation of sensitive electronic equipment. The Tescom 2000 Series offers “Hot Swap” feature that enable the load to be locked to either primary or secondary supply while the switch is removed for maintenance purposes.
