Gensets are becoming more and more reliant on electronic devices or modules to regulate its functioning such as intelligent control Modules (DSE Controllers) as well as original Automatic Voltage regulators (AVRs) and Other electronic modules that allow multiple functions. Controllers function is monitoring an extensive number of engine parameters, display warnings, shutdown and engine status information. An automatic voltage regulator (AVR) is an electronic device for automatically maintaining generator output terminal voltage to ensure proper functioning of Genset.
