2U 16 way Switched Transfer Switch

The switched transfer switch fail-over redundancy to single or dual-power supply servers and network devices. Exclusive to this model is its ability to carry loads on the A circuit, B circuit or both and to remotely manage the outlets.

Similar, but unlike a common automatic transfer switch, the switched transfer switch is unique in that it contains two (2) in-feeds and two (2) banks of eight (8) outlets each, for a total of 16 outlets across the two circuits.

The "A" infeed routinely powers just the A1-8 outlets, and the "B" in-feed routinely powers just the B1-8 outlets. However, if the "A" infeed goes down, the "B" infeed powers all 16 outlets and the same if the “B” infeed goes down. The transfer occurs in fewer than 18 milliseconds, which is faster than the interruption rate of the attached equipment.

This new "Fail-Safe" method has several advantages compared to a standard ATS because it does not prohibit load balancing between the two supplied circuits. 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 on the primary. The "Fail-Safe" method differs in that both circuits are routinely loaded, but only to half capacity. This results in less heat, less resistance, and consequently less of a 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.
