Description

Description

Voltage fluctuation is all too common and does a great amount of damage to sensitive electronic equipment. To avoid the expenses involved in replacing machinery and overtime charges to catch up on production it makes good sense to use an automatic voltage regulator. These autonomous devices catch and correct the voltage before it can cause problems.  The automatic voltage regulator works by measuring the output voltage against a set point. Once a difference has been detected to sends a signal to adjust the excitation of the generator. As the excitation current in the field winding increases the terminal voltage will increase. This solid state unit is far more efficient than the old electromechanical devices as it automatically adjusts the voltage where necessary. Where multiple generators are used the AVR system will have circuits to ensure that all generators operate at the same power factor.

Characteristics of the EA321 Automatic Voltage Regulator

This unit has been designed for use with a permanent magnet generator. A frequency measuring circuit continually monitors the shaft speed of the generator and provides under speed protection. Provision is made for the connection of a remote voltage trimmer to allow the user fine control of the generator’s output. An analogue input allows connection to a controller or other external device. The AVR can be run in parallel with other generators.
