OPERATING MANUAL FOR AUTOMATIC VOLTAGE REGULATOR
MODEL NO : EVC600i
1. INTRODUCTION
2. ENVIRONMENTAL
3. TECHNICAL SPECIFICATION
The EVC600i Voltage Regulator is thyristor base to control the DC exciter field power of conventional
50 or 60 Hz brushless generators. The AVR circuitry includes under speed and over load protection
features. Excitation power is derived directly from the generator terminals.
