DESCRIPTION
The Model 2642 3-Phase Monitor protects electrical
equipment by sensing phase loss, low voltage and reverse
phase conditions. This device uses a combination of
voltage and phase angle sensing, and will detect a phase
loss even when regenerated voltages are present.
The Model 2642 is fail-safe; the output contacts will
transfer when correct power is applied, and trip out on any
fault condition or complete loss of power. Each of five
voltage versions can be adjusted throughout a wide
operating range. An adjustable trip delay timer prevents
nuisance tripping caused by momentary voltage dips.
The DPDT output contacts allow the Model 2642 to be
used in control circuits and alarm circuits. The auto-
matic reset can be converted to a manual reset by
adding a normally closed switch.
