Basler DECS-200-2L Digital Excitation Controller for Generator

Description

Product Overview

DECS-200-2L is a digital excitation control system (AVR) developed by Basler Electric for synchronous generators. It adjusts generator excitation current precisely to stabilize terminal voltage, reactive power and power factor. Widely used in diesel generator sets, hydro generators, gas turbine and steam turbine power units. This model is obsolete by Basler, no longer available for original factory new orders. Only surplus stock, refurbished and used units are supplied for field maintenance replacement.
