Description
Product Overview
The DECS-250-LP1SA1P is a Digital Excitation Control System (DECS) module developed by Basler Electric for precise regulation and protection of synchronous generators in power generation, marine, and industrial applications. Designed to optimize voltage control and dynamic performance, this DECS-250-LP1SA1P excels in managing generator field current, ensuring stability during load fluctuations and grid disturbances. Compatible with brushless or static excitation systems, it supports advanced features like power system stabilizers (PSS) and under-frequency load shedding (UFLS) for grid code compliance in SIL 2 (IEC 61508) environments.
Built for rugged operation, the module operates in **-30°C to +70°C** temperatures and features conformal-coated electronics for protection against humidity and vibration. Its intuitive interface simplifies integration with SCADA systems via Modbus® TCP/IP or IEC 61850 protocols, making it ideal for renewable energy plants, marine vessels, and backup power systems.
