This digital excitation regulator samples generator voltage and current signals, adjusts excitation current through closed-loop control to maintain stable terminal voltage. It integrates overexcitation, underexcitation and overcurrent protection, supports Modbus TCP / RTU for data interaction with SCADA. Dual processor design improves control reliability for generator excitation loop.

Certification: CE, IEC

Dual processor control board, signal sampling circuit, excitation pulse drive unit, communication interface, terminal block and status LED. Common faults include voltage drift, excitation loss, communication interruption and sampling channel failure.
