AC260B-380-480
Over or Under Voltage MonitorRead moreThe Model 260 Voltage Sensor is a single set-point voltage sensor. Input voltages above the set-point cause the output contacts to energize (contacts 1 & 8 closed). Input voltages below the set-point cause the output contacts to de-energize (contacts 1 & 2 closed). The dead band between pull-in and drop-out is less than 2%.The standard unit has a screwdriver, or fingertip adjustable set-point range of approximately 35%. of the maximum voltage. This device can also be provided with a factory calibrated trip point.
AC versions of the Model 260 Voltage Sensor are not frequency sensitive, and may be used in systems from 50 Hz to 400 Hz. DC models are not polarity sensitive. This device requires a standard 8-pin socket, such as Time Mark’s Model 51×120.

B292
Frequency MonitorRead moreThe Model 292 Frequency Monitor is designed to monitor power line frequency. It is intended for systems where line frequency variations will cause improper operation of electrical equipment. A solid-state sensing circuit drives an internal electromechanical relay which is energized when the line frequency is correct. Operating power is drawn from the same line being monitored.The Model 292 is set to the over and/or under frequency trip points using ten binary-coded switches. A frequency variation outside the trip points causes the internal relay to drop out and an appropriate LED indicator to illuminate.
Applications for the Model 292 include stand-by power plants, portable power supplies, and windmill generators.
