Shiva Amvaj Two Relay Astronomical Clock

Using a micro processing 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 timer switch does not use an optical sensor and can be installed indoors.

The two output relays work separately and the delay/hasten configurations for power on/off must be set separately for each.

  • Micro processing unit for calculating sunrise/sunset time
  • Over/under voltage protection
  • Data backup in case of power supply failure (up to five years)
  • With two seperate output relays
  • Adjustable timer for disconnecting output at 1-12 hours after sunset for each output
  • Adjustable disconnect timer (hour and minutes) for each output
  • Delay/hasten output connect/disconnect ±120 minutes relative to sunrise or sunset
  • Replaceable lithium battery lasting up to five years

  • Supply voltage: 180-250 VAC/50-60 Hz
  • Operating conditions:
    • Temperature: -20 to 65 o C
    • Humidity: 70%
  • Disconnect at:
    • Over voltage: 255V
    • Under voltage: 170V
  • Output: two 10A relays
