The Server Technology® Fail-Safe Transfer Switch (FSTS) provides fail-over redundancy to single or dual power supply servers and network devices. Exclusive to the Fail-Safe Transfer Switch is its ability to carry loads on both the A and B circuits during normal operation. Unlike a common automatic transfer switch, the Fail-Safe unit is unique in that the "A" in-feed routinely powers half the outlets, and the "B" in-feed routinely powers the other half. However, if either in-feed goes down, the other powers all outlets. This "Fail-Safe" method has several advantages compared to a standard ATS. A standard ATS contains two-in-feeds, but runs all outlets from just one source, with the secondary source only being used once an outage occurs. The Server Technology design does not prohibit load balancing between the two supplied circuits which results in less heat and a lower voltage drop compared to the same load existing on just one source. Only when an outage occurs on one of the two sources will the entire load be applied to a single source.
