FS300 SERIES
Description
The FS300 Series of solid-state flashers were specifically
designed to operate lamp loads. Their two-terminal series
connection feature makes installation easy. The high immunity
to line noise and transients makes the FS300 Series ideal for
moving vehicle applications. All solid-state construction means
reliability and long life. The FS300 Series offers a factory fixed
flash rate of 75 FPM or may be ordered with a fixed, custom
flash rate ranging from 60 to 150 FPM.
Operation
Upon application of input voltage, the T2 OFF time begins. At
the end of the OFF time, the T1 ON time begins and the load
energizes. At the end of T1, T2 begins and the load de-energizes.
This cycle repeats until input voltage is removed.
Reset: Removing input voltage resets the output and the
sequence to T2.
