Light dependent relay serves to switch-ON the lighting of streets, squares, shop windows, neon lamps etc, at twilight and to
switch-OFF afore mentioned lighting at dawn.
The relay should be situated at place with permanent access to day light, which, due to its changes of intensity, will cause switching ON and OFF the lighting.The exact time of switching the lighting can be set by potentiometer by the user . Turn in the direction of ÔÇťhalf moonÔÇť will delay switching-ON, turning in the direction of ÔÇťsun " will advance switching-ON. The relay is equipped with a delay system, which delays switching ON and OFF the lighting, thus eliminating the influence of accidental disturbances like thunder lightings on the relay functioning.
In the case of control measures light dependent relay tightly cover the entire appliance, such as a cardboard box or a dark, thick cloth. Cover only the "eye" the probe, such as the finger is not enough, because the intensity of sunlight is very strong and is passes to f by a plastic cover and the human body.
Power of receivers:
There is possibility of a special implementation of automatic voltage zmierzchowych other than those indicated in the table of technical data, such as 12V, 24V, 48V and 110V AC / DC and others.
