Astronomical time switch is a microprocessor based timing device which switches ON or OFF external lights, street lights, flood lights as per time. In a normal timing devise we set time as per sunset & sunrise time. This time keeps on changing as per place & time of year like winter time or summer time
In summers months as day light is available longer than winter months so we need to adjust time. Every 30 min of lights wasted is big energy waste & comes with heavy electricity bills.
ELEX Astronomical Time Switch is pre programmed with Sunset & Sunrise time of the place as per its longitude & latitude. One enters the longitude & latitude time once than time switch daily adjust its ON time & OFF time as per Sunset & Sunrise time of that place, saving lot of manual adjustment.
It also has a provision for adjusting the Twilight zone time 0-60 min after sunset & 0-60 min before sunrise. This mean one can set the ON time after or before sunset time as per his needs. Similarly one can adjust OFF time after or before sunrise time both adjustable at user’s end.
Astronomical Time switch has 2 relays
Relay 1 would get ON/OFF as per set time of Time switch
Relay 2 would get OFF after few hours of Sunset & re-ON before Sunrise time saving electricity in the lean period of night hours both timing are adjustable at user's end
