DESCRIPTION
The 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 point(s) causes the internal relay to drop out and an appropriate L E D indicator to illuminate.
Applications for the Model 292 include stand by power plants, portable power supplies, and windmill genera­tors.
