RD-TPA1 series astronomical time switch is for realization of time
functions in the systems of automatics and steering. It will calculate
the sunrise and sunset according to the geographic position and
time zone. Night break program can be used to turn off the output at night.
There is an internal battery which can protect real time clock and
all the settings when the electric power supply is off .
