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.

Use on CAT Gen with PMG, and Shunt. The ADVR-12 is a totally new hybrid 12 Amp universal voltage regulator with a comparable footprint as the Basler* AVC63-12 and AVC125-10, CAT* VR6, KATO* K65-12B and K125-10B, and the Leroy Somer* 202-8634, and many other. To simplify installation, voltage sensing without PT’s up to 520 volts was added, also new DIP & TRIM adjustment compatible with many automatic paralleling and PF controllers in the market. The new CPU design makes the ADVR-12 exceedingly stable, however keeping the analog power circuit for fast response. Single Phase or Three Phase Sensing & Power Input Voltage Regulation < ±0.5% 220/380/440/480VAC Programmable Input IP Switch Selectable 50/60Hz Multiple Excitation System Compatibility: SHUNT, AU X, PMG Inverse-time Over Excitation Protection Under Frequency Protection Soft Start Voltage Ramping EMI Suppression Built-in High Capacity Protection Fuse.
