Strobe Power Supply
 |
| 774-1228 |
The model 774 strobe power supply is designed to alternately flash two groups of remote strobe heads in either high or low intensity and normal or pursuit flash rate. The 774 is controlled
manually by 4 customer provided SPST low current switches which select high-low intensity, flash rate, lamp group 1 on-off
control, and BOTH lamp groups on-off control. All functions may be wired to allow control by a single low current switch if
desired. The 774 operates from 12–28VDC and is fully potted making it vibration and water resistant. It also features polarity
protection, heavy duty precision circuitry, and RFI filters to minimize radio interference. The power supply is constructed
with a glass filled Lexan® case and polyurethane potting.
