Description
The BASLER ELECTRIC DECS 125-15 (Part Number 9265300129) is a digital excitation control system designed for automatic voltage regulation and excitation control of synchronous generators. It is a microprocessor-based excitation controller used in brushless and brush-type AC generator systems for industrial power generation, marine generators, and turbine generator applications.
The DECS 125-15 regulates generator output voltage by controlling the exciter field current and provides functions including voltage regulation, excitation limiting, voltage matching, VAR/power factor control options, and generator protection features. It can receive power from a permanent magnet generator (PMG) source or a shunt-excited generator output through the DECS power module.
The 9265300129 model is a DECS 125-15 configuration designed for systems requiring up to 125 VDC continuous field voltage and 15 ADC continuous field current output. It is commonly used as a replacement excitation controller in marine and industrial generator control systems.
