Description
ASTRO is a digital time switch that calculates the sunset,sunrise and prayer times by using coordinates and real time clock. It operates according to the program setting and it has no need for a photocell sensor. Device could be used as astronomical, prayer or digital time switch. ASTRO has two reserves to protect the real time clock and calender against power outage. For long term reserve there is CR2032 battery. If the device is powered, battery life is approx. 5 years. When the battery life is expired,the user is able to replace the battery easily. Super capacitor is used for short time power failures. It supplies the device for 3-7 hours. In this case battery is not used, so battery level is conserved.
