AC Crossing Light Controller Kit

Single Channel Light Controller

by Galak Electronics
Part No. VG-304B
Shipping Weight: 0.9 ounce (29 grams)

If you're looking to power up warning signal or construction flasher, the Single Channel Light Controller is the perfect solution. The universal input accepts both 120VAC and 240VAC line voltages and provides up to 500 Watts of power per channel. In fact, our controller is powerful enough to drive any full-sized incandescent traffic light, yet sensitive enought to work with the most cost-efficient LED bulbs all the way down to 4 watts. Solid state outputs also means both inductive and non-inductive loads can be switched effortlessly for years.

There are four different modes including a 50-50 on-off flasher, single strobe flash, double strobe flash, and a random flashing mode. Adjusting the duration allows for a full range of timing possibilities. The unit comes with quick installation instructions and four (4) adhesive standoffs for effortless mounting on virtually any surface. Click here to add a 6' power cord to your order.
