Will operate any lamp in the designated circuit
for the duration of the generator supply.
DESCRIPTION:
PRODUCT ADVANTAGES
The IOTA ETS Emergency Transfer Switch allows the use of auxiliary generator power
on a switched fluorescent fixture in power failure situations. The ETS senses the loss
of normal AC power and switches the AC ballast to the auxiliary generator supply. The
ETS will operate the lamps at full light output for as long as the generator is able, and
will work in conjunction with any lamp type and fixture on the generator circuit. Dimming
ballasts require one ETS for each hot lead.
Full Light Output
Allows Auxiliary generator power on a
switched fixture
