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.
