2.英文详情介绍
GE DS200DSFBG1ACB Controller Module
The GE DS200DSFBG1ACB is a driver/shunt feedback board in the Speedtronic Mark V turbine control system, mainly used for excitation current control and feedback in the electro-hydraulic control circuit.
Product Features
Receive 4-20 mA control instructions from AVR and output 0-10 A excitation current to drive the magnetic field winding of the exciter.
Built in PI closed-loop regulation, real-time collection of shunt feedback current and sending it back to AVR, with control and feedback accuracy of ± 0.5% of full scale.
Equipped with soft start (approximately 2-second slow rise), current limiting protection (default 110% rated value), and feedback disconnection detection function.
The front panel is equipped with Power/Run/Fault tri color LED and zero/full adjustment potentiometer, supporting on-site calibration and manual excitation adjustment.
Standard VME single board structure, 24 V DC power supply, operating temperature 0-60 ° C, MTBF exceeding 120000 hours.
Application Fields
Automatic voltage regulation (AVR) excitation control for large thermal power plant generators.
Automatic regulation of reactive power of hydropower station generators.
Excitation control of gas turbine driven generator.
The factory provides voltage stability control for its own power plant generator.
Synchronize camera excitation adjustment.
