The ADVR-073 is an advance (Hybrid Analog/Digital Voltage Regulator) design for general-purpose isochronous applications. The ADVR-073 uses an reliable CPU (Central Processing Unit) in its design. This eliminates complex analogue components and circuits that are inherently over sensitive to temperature eliminating voltage instabilities and drift. In addition, we added over excitation and loss of sensing shutdown protections, with matching U/F, O/E LED indicator lights. Consequently, this AVR prevents the generator from excitation overload, preventing exciter and regulator damage. It is easy to install and flexible for use in both shunt type and generators with auxiliary windings.
