AVR Voltage Regulator AN-5-203

AVR Voltage Regulator AN-5-203 Description

The AN-5-203 automatic voltage regulator is a partially sealed electronic device for generators. It works by controlling the exciter's excitation current to automatically adjust output voltage, offering high voltage stability and automatic operation. Constructed with high-quality materials, it is strong and has a long service life, with a small size for easy carrying, storage, and use. Technical data: 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 be greater than 5 ohms. The steady state voltage adjustment rate is less than plus or minus 0.5 percent, with a voltage adjustment range exceeding 15 percent. Minimum residual magnetizing excitation voltage is greater than 5V at 30Hz. Voltage fine-tuning via an external 1 k ohm/1W potentiometer gives plus or minus 12 percent; if unused, the connecting piece is shortened.
