AVR M40FA640A Brushless Alternator Replacement Marelli Automatic Voltage Regulator

• The whole body of regulator is insulated and is safer to use in harsh environments.

• The product uses high-quality electronic components to maintain high reliability under harsh environmental conditions (high humidity, dust, salt environment).

• This regulator is suitable for single and three phase generators.

• The adjustment accuracy of the regulator is high, and the theoretical fluctuation is only 0.5%.

• The board of the regulator is made of flame retardant and high temperature resistant material, which is safe and durable.
