AC voltage regulator ADVR-321

three-phasefor alternatorfor generator sets

ADVR-321 features 3 Phase RMS voltage sensing, suitable for permanent magnet (PMG) brushless generators and capable of use in paralleled generator sets. It adopts a new digital circuit for voltage sensing and under frequency protection, it can effectively minimize the output voltage variations and under frequency knee point drifted affected by the changes of environment temperature. ADVR-321 upgrades the power module and enlarges the heat sink to optimize thermal performance while maintaining excellent stability. Compatible with Newage Stamford MX321 AVR, Onan 305-0823. All manufacturer names and numbers are used for reference purpose only and do not imply that any part is the product of these manufacturer. ● 3 Phase RMS Reading for Sensing Input ● Provides current limiting function when the generator output is short-circuited. ● Built-in LED indicator for displaying under-frequency, overvoltage, overcurrent, and over-excitation conditions ● Voltage regulation less than +/-0.5% RMS ● For use in parallel operation ● Digital circuit for voltage sensing and under frequency protection, it can effectively minimize the output voltage variations and under frequency knee point drifted affected by the changes of environment temperature. ● When the AVR detects an abnormal generator condition (over-excitation, over-voltage, or over-current), it can supply power to the MCCB trip solenoid to disconnect the load from the generator.
