Generator AVR DVR2000E Marathon Used AC Brushless Alternator Generator Voltage Regulation
Specification
- Dvr 2000e marathon generator regulates the output voltage of a brushless, ac generator by controlling the current into the generator exciter field. Input power to the DVR2000E is from a multi-pole, high-frequency, permanent magnet generator (PMG).
- Generator digital AVR DVR 2000E is supplied in an encapsulated package designed for behind-the-panel mounting.
The DVR2000E is held in place by thread-forming screws that thread into its plastic shell. Front panel indicators (LEDs) annunciate regulator status and system conditions. DVR2000E connections are made through quarter-inch, quick-connect terminals on the rear panel. A 9-pin DB-9 type connector on the rear panel provides communication between the DVR2000E and an IBM compatible PC.
