The Basler Electric DECS-250-LN1SA1N is a complete digital excitation control system designed for precise voltage, var, and power factor regulation in synchronous generator and synchronous motor applications. This unit features True RMS sensing for single-phase or three-phase voltage and current inputs, alongside integrated generator protection functions (27/59, 81O/U, 32R, 40Q, EDM, 59F, 51F, Loss of PMG, Field Short Circuit, and 25 Sync Check). The DECS-250-LN1SA1N configuration provides automatic voltage regulation (AVR), field current regulation (FCR), field voltage regulation (FVR), and load sharing capabilities over Ethernet.
