ORDERING INFORMATION:
The voltage threshold SR Relay controls a voltage supply which
is its own supply. The output relay is energized when the supply
(effective for AC) exceeds the selected threshold. It de-energizes
when the controlled supply falls below (5 to 20% Hysteresis) of
the supply voltage or when the input power breaks. Hysteresis
is controlled by a potentiometer and its selection does not
change the chosen threshold. Pulses or drops of 100ms or
less are ignored.
