by Galak Electronics
Part No. VG-305B
Shipping Weight: 1.15 ounce (33 grams)

NEWLY improved with the latest in solid state technology, our AC Traffic Light Controller is the perfect solution for all of your traffic signal needs. Accepting standard 120VAC line voltage (240VAC available), this controller provides over 500 Watts of power per channel and will drive full-sized LED and incandescent traffic lights (This includes all household bulbs). Solid state outputs also means both inductive and non-inductive loads can be switched effortlessly for years. 25 thoughtfully considered sequences have been packed into the microcontroller and are easily selected with the push of a button. The unit comes with quick installation instructions and four (4) adhesive standoffs for effortless mounting on virtually any surface. Select Accessories above to add a power cord.
