Generator AVR Electronic AN-5-203

Generator AVR Electronic AN-5-203 Description

This automatic voltage regulator, model AN-5-203, is a partially sealed electronic component designed for generators. It automatically regulates voltage by controlling the generator exciter's excitation current, ensuring high stability and easy operation. Made from quality materials, it is durable, long-lasting, and compact for convenient storage and transport. Key specifications: auxiliary winding input AC 55V-220V, maximum excitation voltage output 120V/5ADC/10S, main winding voltage input 400VAC at 50/60Hz. Low frequency protection is adjustable for 50 or 60 Hz. Generator magnetic field resistance must exceed 5 ohms. The steady state voltage adjustment rate is less than plus or minus 0.5 percent, and voltage adjustment range is greater than 15 percent. Minimum residual magnetizing excitation voltage is over 5V at 30Hz. With an external 1 k ohm/1W potentiometer, voltage fine-tuning is plus or minus 12 percent; without one, the connecting piece is shortened.
