Flashers and Tower Lighting Controls
Flashers
FSU1000 SERIES
Description
The FSU1000 incorporates an onboard adjustable flash rate
of 10 to 100 FPM and a universal input voltage in one device.
Its circuitry is encapsulated and is capable of controlling loads
of up to 20A. The versatility of the FSU1000 makes it ideal for
applications where various flash rates and operating voltages
are required.
Operation
When input voltage is applied to terminal 2 and the load (lamp),
the load energizes steadily. When input voltage is applied to
terminal 3, the output flashes.
Optional Low Current Switch (S1):
This low current switch
could be a limit switch or contact. While open, the operator sees
the load (lamp) ON and operating. When the limit switch closes,
the load (lamp) flashes to attract attention.
