2628
Over or Under Voltage MonitorRead moreThe 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 de-energize. Input voltages above the set-point cause the output contacts to 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.

268
Voltage Band MonitorRead moreThe Model 268 Over & Under Voltage Monitor is designed to ensure that the monitored operating voltage remains within a 120 VAC band. This device uses a dual op-amp comparator circuit to achieve stable and repeatable trip set-points.The output relay is energized only when the voltage being monitored remains between the upper and lower set-points. Voltages above or below the set-points will de-energize the relay, and illuminate the appropriate indicator LED.
The Model 268 Over & Under Voltage Monitor is designed for continuous duty operation.

2681-110VDC
Voltage Band MonitorRead moreThe Model 2681 Voltage Band Monitor is a dual set-point voltage monitor. Input voltages between the upper and lower set-points will cause the output contacts to pull in (contacts 1 & 3 closed) and the LED indicator to illuminate. Input voltages above or below the set-points will cause the output contacts to drop out (contacts 1 & 4 closed) and extinguish the LED indicator.The Model 2681 is available in AC or DC versions. AC models of the 2681 are not frequency sensitive and can be used on systems from 50 to 400 Hz. The voltage set-points are screwdriver adjustable over a wide operating range.
The SPDT output configuration is identical to the configuration of general purpose relays. This unit requires a standard 8-pin socket for mounting.
