Shiva Amvaj Astronomical Clock 6A & 20A

Via 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 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.
