AVR Brushless Automatic Voltage Regulator for Diesel Generator, AVR-20 for AlternatorsSpecification:Part Number: AVR-20 AVROutput Current: 2-20AOutput Voltage: 0-115VPhases: Single PhaseFrequency: 50/60 HzPackage Includes: 1pcs AVR-20 AVR20 Automatic Voltage Regulator Features:1.The AVR-20 is engineered to work seamlessly with all brushless alternators. It utilizes a half-wave thyristor diode for accurate voltage control and requires only 5V AC residual voltage to initiate operation.2.Encased in resin with an open-chassis design, this regulator contains no moving parts, ensuring reliable performance even under high levels of vibration and in harsh conditions.3.Featuring Proportional-Integral (PI) control, the unit quickly responds to load variations to maintain stable voltage output. A built-in stability adjustment potentiometer allows compatibility with a wide range of alternators.4.Capable of supplying up to 20A of DC excitation current at 115V, the regulator offers both built-in and external voltage adjustment options via a 1 kilohm potentiometer.5.Includes a shielded circuit that reduces excitation voltage when frequency drops below 45 Hz, precautionary engine overload and enabling secure shutdown under electrical load.

• Universal Compatibility: Designed for seamless integration with all brushless alternators, the AVR-20 ensures reliable voltage regulation by monitoring phase-to-neutral voltage and adjusting excitation current via a half-wave thyristor diode. Its self-excitation requires only 5V AC residual voltage for startup
• Encapsulated Construction: Featuring a robust open-chassis design with resin encapsulation, this voltage regulator operates without moving parts, making it perfect for high-vibration environments. Its compact form factor allows straightforward mounting within the alternator terminal box
• Intelligent Voltage Regulation: Equipped with Proportional-Integral (PI) control, the AVR-20 delivers rapid response to load changes while maintaining accurate voltage stability. An integrated stability potentiometer allows fine-tuning of reaction speed to match various alternator characteristics
• Excitation Output: With a maximum DC output of 20A and 115V, the regulator supports strong excitation performance. Voltage adjustment is facilitated through an built-in potentiometer, with provisions for an external 1 kilohm potentiometer for remote control
• Low-Frequency: A built-in frequency conservation circuit shields diesel engines by reducing excitation voltage when frequency drops below 45 Hz. This blocks excessive torque during motor overload or shutdown, enabling secure engine operation under electrical load
