Shiva Amvaj Astronomical Clock 6A & 20A

Via a micro porosessing program, the device can accurately determine sunrise/sunset times every day with out receiving light in order to control the lighting system using two outputs. This astronomical clock does not use optical sensor and can be installed in roofed places, thus preventing errors in cloudy days or unauthorized access.

The device can power on/off the outputs ±120 minutes relative to sunrise or sunset.


  • Controlling lighting systems according to longitude and latitude
  • Over/under voltage protection
  • Data backup in case of power supply failure (up to five years)
  • Adjustable disconnect timer (hour and minutes) for each output
  • Delay/hasten output connection/disconnection ±120 minutes relative to sunrise or sunset
  • Fixed/rotational display of date, hour, and power on/off time
  • Adjustable timer for powering off the lighting system at an exact time or disconnecting output 1-12 hours after sunset for each output
