Users should thoroughly review the technical data before selecting a product part
number. It is recommended that user also seek out the pertinent approvals files of
the agencies/laboratories and review them to ensure the product meets the
requirements for a given application.
Sensing Modes
The CS can be used as an over or undervoltage sensor, depending upon
whether the load is connected to the normally closed (NC) or normally open
(NO) contacts of the sensor’s output relay.
Overvoltage sensor
– The NC contacts are used. The relay remains de-
energized until an overvoltage is sensed.
Undervoltage sensor
– The NO contacts are used. The relay remains en-
ergized until the voltage decreases to the preset level, where the sensor
de-energizes the relay.

Adjustable Voltage Sensor Operation
Note 1
– As voltage increases, the
relay will pick-up at its selected
point and remain energized while
voltage is maintained at that level or
higher.
Note 2
– As voltage decreases, af-
ter pick-up, the relay will drop-out at
its selected point.
Note 3
– Minimum hysterisis, the
voltage differential between pick-up
and drop-out, is typically 2% of
pick-up.
Ordering Information –
Distributors are more likely to stock boldface items.
