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. Features & Benefits FEATURES BENEFITS T otally solid state and encapsulated No moving parts to arc and wear out over time and encapsulated to protect against shock, vibration, and humidity High immunity to line noise and transients Designed specifically for moving vehicle applications High surge current capability (10 times steady state) Direct operation of incandescent lamp loads T wo terminal series connection Provides quick and easy installation for new or existing applications Accessories P1023-6 Mounting bracket The 90° orientation of mounting slots makes installation/removal of modules quick and easy.
