Product Description
Basler Electric DECS-100-B15 is a digital excitation control system (digital AVR, automatic voltage regulator) from DECS-100 family, equipped with a 32-bit microprocessor for synchronous generator excitation regulation. B15 denotes the 15A continuous field output power stage. It precisely controls generator field current and stabilizes terminal voltage. Integrated PSS (Power System Stabilizer), full protection functions including excitation limits and loss-of-sensing detection, event logging and Modbus RTU communication. Suitable for standalone operation and multi-generator paralleling. It is critical excitation spare part for power stations and cogeneration units.
