ET90000 Series
Input power terminals take any
voltage from 120 to 277 VAC,
50/60 Hz. The transition
is automatic.

Photo control in parallel with the
load. Either the time switch OR
the photo control must be on to
power the load. Ideal for improved
safety. Loads will activate during
the scheduled times or if the area
is dark, from conditions such as a storm.
Bi-level lighting installation.
Multiple loads may be split across
different circuits to allow them to
be controlled independently. Allows
for ON/DIM/OFF instead of ON/OFF.
Ideal for peak, off-peak, and closed
business hours.
Typical electronically held
contactor. The contactor is driven
by a single circuit, using both the
normally open and normally closed
terminals. One input of the
contactor will always be powered.
More loads may be wired
concurrently, within the maximum
output ratings of the contactor.
Energy savings by 'dimming'
output. Allows for ON/DIM instead
of ON/OFF. Ideal for maintenance
or security applications where
some light is always required. The
manual disconnect switch is
recommended.
