Product Description
Product Overview
The Basler DECS-250-LN1SN1N is a Digital Excitation Control System from the DECS-250 series, designed to provide precise voltage regulation, protection, and monitoring for brushless excited AC synchronous generators. Manufactured by Basler Electric, this microprocessor-based system delivers a 15 A pulse width modulated (PWM) power stage, offering robust field forcing for low-voltage applications (32 V DC output). It is widely used in industrial power generation settings, such as oil & gas, manufacturing, and utilities, where reliable excitation control is critical for generator performance and stability.
