DESCRIPTION
The
Model 2602 Voltage Sensor
is a rapid response
device for sensing a low voltage condition on 120 VAC,
60 Hz, single phase power systems.
Operating power is
drawn from the same line being monitored.
Upon sensing a voltage below 80 VAC, 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 (8.33 msec.), plus the flight time of the relay (20
msec. max.). When the voltage rises above 84 VAC, 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.
