Product Description


Shiva Amvaj Two Relay Astronomical Clock

Using a micro processing program, the device can accurately determine sunrise/sunset time every day without receiving light and control the lighting system using two outputs.
The astronomical clock does not use an optical sensor and can be installed indoors.
The two output relays work independently and the delay/hasten configurations for power on/off are set separately for each.
  • Micro Processing unit for calculating sunrise/sunset time based on longitude and latitude
  • Over/under voltage protection
  • Data backup in case of power supply failure (up to five years)
  • Two independent output relays
  • Adjustable timer for disconnection timing (based on hours and minutes) for each output separately
  • Adjustable lead/lag time in output connection/disconnection timing relative to sunrise or sunset (±120 minutes)
  • Replaceable lithium battery with 5 year lifespan
