The AVC63-12 and AVC125-10 voltage regulators are designed to control the output of a brushless excited synchronous generator. They are designed to be very rugged, are perfect for a variety of applications, and are especially suitable where the generator is installed in a harsh environment. They can accept supplemental control inputs for utility paralleling applications where a VAR/PF control and Over/Under Excitation Limiter are used. These regulators are extremely flexible and offer jumper selection provisions for single- or three-phase sensing, 1 or 2X V/Hz, and can accept 1 or 5 Amp CTs. The power stage can accept a frequency range of 50-400Hz, and the sensing can be configured for 50/60 or 400Hz. FEATURES ± 0.5% voltage regulation 0.5% accuracy up to 20% THD (harmonic associated with 6 SCR loads) Outputs of 63Vdc @ 12Adc and 125Vdc @ 10Adc from a PWM output stage 1 or 2X V/Hz limiting (jumper selectable) Single- or three-phase average sensing (jumper selectable) Paralleling input from 1 or 5A CT secondaries Nominal sensing inputs of 120, 240, 50/60Hz or 400Hz Power input from shunt connections or PMGs operating at 50 to 400Hz Accessory input Over excitation shutdown
