Genuine product! - Worldwide Shipping

The D550 digital automatic voltage regulator (AVR) provides excitation current up to 7 A with excellent reliability and precision for SHUNT, permanent magnet (PMG) or AREP (auxiliary winding) excitation types.

D550 includes advanced protections such as over-excitation limitation and voltage sensing loss, and also features voltage droop for genset parallel operation. The D550 is also equipped with a Load Acceptance Module (LAM) to handle load impact events.

The D550 AVR is also optimized for grid paralleling operation, and complies with the latest grid code regulations, including the latest German grid code regulations VDE 4110 and VDE 4105. In this context, the D550 also includes active & reactive reverse power alarms.
