Overview
The Sentry Fail-Safe Transfer Switch (FSTS) features two input power feeds, from separate AC circuits, to supply single-power equipment with dual, redundant power sources. A primary AC circuit provides power to the connected device(s). With this rack automatic transfer switch, if the primary source becomes unavailable for whatever reason, then the Sentry FSTS auto-switches to the secondary power source to support the connected equipment.
The transfer from one power source to the other is seamless to the connected equipment with this rack automatic transfer switch. When the secondary power source is available, an interruption of the primary power source will not affect the equipment�s uptime or performance.
Unique to the Sentry FSTS is the ability to designate which power source is primary and which is secondary. With the Primary Select switch, a power engineer simply toggles the switch from primary to secondary, which transfers the load from one power feed to the other. Now, the "secondary" becomes "primary" and the power engineer can safely work on the first power source without dropping power to the connected equipment.
Also exclusive to the FSTS is the ability to select the high voltage (208-230V) or low voltage (110-120V) operating range of the AC power source. Use the Sentry FSTS as a universal power transfer switch for all cabinets and servers, regardless of the voltage. To apply power, just remove a panel and then choose the appropriate voltage range to the Fail-Safe Transfer Switch.
