SPT SERIES
Photocell 120V, 240V, 347V
The SPT series controls combine the superior performance of the AT series with an economical, yet highly durable, polycarbonate housing. These controls feature a heavy-duty thermal bi-metal switch that provides a 30-45 second time delay. This virtually eliminates unwanted lamp cycling that could be caused by lightning, car headlights, or other sudden changes in the ambient light level.
