Description
The Model 2642 protects electrical
equipment by sensing phase loss, low voltage and reverse phase
conditions. The monitor 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 the five voltage versions can be
adjusted throughout a wide operating range. An adjustable
trip delay timer prevents nuisance tripping caused by momentary
voltage dips. LED indicators show NORMAL (green) and TRIP
(red) status.
The Model 2642 has an automatic
reset which can be converted to manual reset with the addition
of a normally closed switch. The DPDT out put can be used
in motor control circuits and/or alarm circuits.
