Description:
The AS-5-203S is a half-wave phase-controlled thyristor Automatic Voltage Regulator (AVR) designed for brushless generators. It regulates generator voltage while providing under-speed and sensing loss protection for safe operation. The AVR ensures positive voltage build-up from residual levels using high-performance semiconductors, delivering closed-loop control of output voltage with a load regulation of ±1.5%.
