The An-5-203 is an electronic device that monitors generator output voltage. It automatically adjusts the direct current (DC) excitation current sent to the rotor field windings. This constant adjustment stabilizes the alternating current (AC) output during load changes. It is commonly found in 2kW to 5kW single-phase gasoline and diesel generators.
