Description: Gelco Auto Photo is useful in large external lighting installations requiring switching off lights dependent on natural day light and manual controls posing constraints on account of distances covered. It switches on the lights at dusk and switches off the lights at dawn at places like airport runway lights, railway station lights, advertisement neon sign displays, stockyards and housing colonies. The system employs a light sensor exposed to the natural light which generates an electrical pulse and activates an electromagnetic relay cutting off the electric current. A potentiometer is provided for the final setting. The unit is available in single phase up to 25 A and in three phase up to 200 A available both as an indoor as well as an outdoor model. The basic unit measures 170 x 165 x 85 mm and weighs 1.5 kg for 25 A rating.
