Breadcrumb Home Parts & Service Service Parts AVRs AVRs Automatic Voltage Regulators (AVRs) are the heart of your alternator's performance. They ensure consistent voltage output, which is crucial for the smooth operation and longevity of your entire power generation system. Our genuine AVRs are the best at monitoring the voltage output of the alternator. These AVRs continuously monitor the voltage output of the alternator. If the voltage drops, they increase the excitation current to boost output. Conversely, if the voltage rises, they reduce excitation to maintain a stable level. Our comprehensive range of genuine analogue and digital AVRs are built to withstand even the toughest environments: Under-frequency protection safeguards your system against power dips. Over/Under excitation protection prevents damage from voltage fluctuations. Moisture and vibration resistance ensures reliable operation in harsh conditions. Compliance with CE, UKCA, CSA and RoHS standards guarantees safety and environmental responsibility. Don't settle for imitations.
