Description

The Teledyne Bowtech ST4K, Xenon rechargeable submersible strobes are self-contained, compact, high intensity xenon beacons designed for use as a visual aid to locate submersible vehicles, or instrumentation packages when they surface for recovery. They can also be used to mark underwater objects, vehicles, divers or work sites.
The strobe is designed such, that when the ROV power (120 to 240Vac) is on, it will still switch the charging circuit for the strobe batteries on and switch the strobe off to conserve battery power. The strobe will constantly charge when the power is present, however the charging will switch off when the voltage on the batteries reaches the fully charged level.

Key Features:
– ​4,000 Metre Depth Rated
– Rechargeable
– High Intensity
– Pressure, Hand and Daylight Switch
