SECTION 1 : SUMMARY

The ADVR-073 is an advance (Hybrid Analog/Digital
Voltage Regulator) design for general-purpose
isochronous stand alone applications. The ADVR-073
uses an extremely reliable CPU (Central Processing
Unit) in its design. This eliminates complex analogue
components and circuits that are inherently over
sensitive to temperature anomalies, as a result
eliminating voltage instability and drift.

SECTION 2 : SPECIFICATION

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, with its
resulting exciter and regulator damage. It is easy to
install and flexible for use in both shunt type and
generators with auxiliary windings.
