The Leroy Somer R250 Voltage Regulator AVR is an analog Automatic Voltage Regulator (A.V.R.) and is power controlled via transistors. The R250 AVR is designed for small/low voltage alternators used in applications such as stand-by, rental, agriculture, marine, telecom, and construction.
The Leroy Somer R250 AVR is designed to maintain a constant voltage level automatically. The AVR has several components like diodes, microcontrollers, potentiometers, capacitors, and resistors placed on its circuit board. It is mounted near your generated and connected via several wires to measure and adjust the generator output voltage.
