Feature: 1. An environmentally friendly product, control the output of a brushless excitation synchronous generator equipped with a single‑phase permanent magnet generator. 2. The perfect alternative to for Marathon electric machines for DVR 2000E/DVR 2000EC voltage regulators. 3. Four control modes: automatic voltage regulation (AVR), manual or excitation current regulation (FCR), power factor (PF) regulation and reactive power (var) regulation. 4. Six protection functions: over‑excitation shutdown, generator over‑voltage shutdown BE2000E over‑temperature shutdown, generator loss‑of‑inductance shutdown, over‑excitation limit and crowbar shutdown. 5. The front panel human machine interface (HMI) indicates the status of the system and BE2000E, and provides the ability to adjust settings on the front panel. 6. Rear RS‑232 communication port for personal computer communication, using BESTCOMS‑B E2000E for Windows‑based software for fast, user‑friendly, setup and control.
