Sentry Fail Safe Transfer Switch (FSTS)
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.
