2602
Under Voltage MonitorRead moreThe Model 2602 Voltage Sensor is a rapid response device for sensing a low voltage condition on 120 VAC, 60 Hz, single phase power systems. Operating power is drawn from the same line being monitored.
Upon sensing a voltage below 80 VAC, the internal relay, which is energized under normal operating conditions, will drop out.The solid-state sensor will respond in one-half of an AC cycle (8.33 ms. ), plus the flight time of the relay (20 ms. max. ). When the voltage rises above 84 VAC, an internal 10-second timer begins. When the time delay elapses the relay will automatically re-energize.

C292
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.

160BR480
Over or Under Voltage MonitorRead moreThe Model 160B(R) Voltage Sensor is a single set-point voltage sensor. Input voltages above the set-point cause the output contacts to energize. Input voltages below the set-point cause the output contacts to de-energize. The dead band between pull-in and drop-out is less than 1%.Wiring connections are made to 1/4 in.; quick connect terminals. Standard versions have a 2-second restart delay. The R versions of the Model 160B have a fixed 5-minute short cycle delay. The Model 160B has a screwdriver adjustable set-point range of approximately 35% of the maximum voltage. The unit can be factory calibrated to meet specific requirements.
AC versions of the Model 160B are not frequency sensitive and may be used in systems from 50 to 400 Hz. DC versions, or other short cycle periods, are available on request.
