DESCRIPTION
The Model 2602 Voltage Sensor is a rapid response
device for sensing a low voltage condition on 120VAC,
60Hz, single phase power systems. Operating power is
drawn from the same line being monitored.
Upon sensing a voltage below 80VAC, the internal
relay, which is energized under normal operating
conditions, will drop out.
The solid-state sensor will respond in one-half of an AC
cycle (8.33ms.), plus the flight time of the relay (20ms.
max.). When the voltage rises above 84VAC, an
internal 10-second timer begins. When the time delay
elapses the relay will automatically re-energize.
There are no field adjustments or calibrations to the
device.
