Automatic Regulator AN-5-203 AVR

Automatic Regulator AN-5-203 AVR Description

This automatic voltage regulator, model AN-5-203, is a partially sealed electronic component for generators. It automatically adjusts the generator output voltage by controlling the exciter's excitation current, providing high voltage stability and straightforward operation. Crafted from high-quality materials, it is durable and long-lasting, and its small size makes it easy to carry, store, and use. Key details: 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. The generator magnetic field resistance must exceed 5 ohms. The steady state voltage adjustment rate is less than plus or minus 0.5 percent, with a voltage adjustment range over 15 percent. Minimum residual magnetizing excitation voltage is greater than 5V at 30Hz. Voltage fine-tuning using an external 1 k ohm/1W potentiometer provides plus or minus 12 percent adjustment; if not used, the connecting piece is shortened.
