2628 AC/DC Voltage Monitor from Time Mark
The Model 2628 AC/DC Voltage Monitor is designed to continuously monitor any AC or DC voltage from 15 to 260 volts.
Input voltages below the set-point cause the output contacts to energize. Input voltages above the set-point 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 voltage 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.
