AVC63-4 Automatic Voltage Regulator For Basler Input 190-240VAC 4A

Description:

The Basler AVC63-4A Automatic Voltage Regulator is a solid-state excitation control device used in brushless generator systems to maintain stable AC output voltage. It regulates generator field excitation by monitoring sensed AC voltage (190–240 VAC input range in this configuration) and adjusting DC field current to stabilize output under varying load conditions.

Applications:

The Basler AVC63-4A used in diesel generator sets, standby power systems, and industrial alternators. Commonly installed in generator control panels for OEM builds, replacement of failed AVR units, and maintenance of Basler AVC63-series excitation systems in commercial and industrial power generation equipment.
