DESCRIPTION
The
Model 2628 AC/DC Voltage Monitor
is designed
to continuously monitor any AC or DC voltage from 15
to 260 volts.
Input voltages above the setpoint cause the output
contacts to energize. Input voltages below the setpoint
cause the output contacts to de-energize. The dead
band between pull-in and drop-out is less than 5%.
Dip switches are used on the Model 2628 to choose
between AC and DC voltage monitoring, and to select
one of the eight trip level ranges. Each trip level has a
35 volt range, with a 5 volt overlap between the ranges.
The unit has a screwdriver adjustment to set the exact
trip point within that 35 volt range.
