Brand: GE Description: High Voltage Gate Interface Board Condition: Brand New Certificate: COO TEST REPORT WARRANTY LETTER Warranty: 1 year Inventory Qty: 7 Payment Term: T/T Shipping Port: Xiamen The DS200FHVAG1ADA High Voltage Gate Interface Board belongs to the Speedtronic Mark V turbine control system DS200 series. The supporting system includes LCI (Load Commutated Inverter, load converter inverter/Static Starter), which is mainly used for starting and driving gas turbine/steam turbine generator
The DS200FHVAG1ADA is a high-voltage gate interface board of the DS200 series for the GE Mark V turbine control system. It is compatible with the gas turbine LCI static start device and drives 77mm high-power SCR thyristors. It uses a pulse transformer to isolate the transmission of trigger pulses, isolate high and low voltage circuits, and simultaneously monitor the voltage across the thyristor and feedback the status, facilitating the system's identification of SCR-related faults. The board card is passively powered and comes with a status indicator light. Each board corresponds to one SCR. Faults can easily cause phase loss in the starter and lockout during unit startup. When replacing spare parts, complete models should be matched. Before operation, high-voltage discharge protection measures should be taken.

Core Functions
Isolation Transmission of SCR Gate Trigger Pulse: The low-voltage trigger pulse from the control board is isolated by a pulse transformer to drive the high-power SCR, blocking high-voltage side interference and protecting the front-end control circuit.
SCR Cell Voltage Monitoring: Continuously acquires the voltage across the thyristor to determine whether the SCR is in a blocking or conducting state.
Fault Status Feedback: The SCR voltage status signal is sent back to the FGPA (Gate Pulse Amplifier) pulse amplifier board; the system judges based on the feedback: thyristor open circuit, short circuit, no trigger, or false trigger fault, triggering system protection.
Local Power Status Indicator: LED lit = High-voltage blocking voltage exists in the SCR power circuit, an important safety reminder during maintenance.
Application
Static starter (LCI) for gas turbines and steam turbines in power plants;
Variable frequency drive (VFD) starting system for large synchronous generators;
Mark V control system for large turbine units in the oil and gas industry.
Q&A 1
Q: What system does the DS200FHVAG1ADA belong to, and what equipment is it mainly used in?
A: It is the GE Mark V control system DS200 series high-voltage gate interface board, mainly used in gas turbine LCI static start-up devices to drive 77mm high-power SCR thyristors within the device.
Q&A 2
Q: What is the core function of the DS200FHVAG1ADA?
A: It transmits SCR trigger pulses through pulse transformer isolation, isolating high and low voltage circuits; it monitors the voltage across the thyristor in real time and sends back signals for system diagnosis of thyristor open circuits, triggering abnormalities, and other faults.
Q&A 3
Q: What are the key points to note when replacing the DS200FHVAG1ADA?
A: Only the complete model DS200FHVAG1ADA should be used; other versions cannot be mixed; the high-voltage circuit should be fully discharged before operation; after replacement, a trigger test should be performed to confirm that the signal and status feedback are normal.
