Photocell Control

In some installations, combining more than one control method provides the best solution. For example, a twilight sensor switches lighting according to actual ambient light, while a time switch can limit operation during quieter hours.

Benefits include switching off public lighting during periods of low use, such as midnight to 4 a.m., adapting more closely to real conditions, and retaining basic operation if one device fails. PRVO 1 enclosures combine a twilight sensor with a time switch. When set correctly, all outputs switch on after dusk, switch off at a set time, switch on again at a set time and switch off after dawn. This helps reduce lighting costs through accurate switching and a scheduled off period.
