Three core functions

SCR status monitoring: DS200FGPAG1ALD collects voltage information of thyristor modules through optical fiber interfaces (such as 15 optical fiber connectors), supports data aggregation of up to 12 field high-voltage components (FHVA), and provides real-time feedback to the LCI (load-commutated inverter) controller.

Gate drive: DS200FGPAG1ALD provides gate power for the three-phase SCR bridge to ensure synchronous triggering of the thyristors, supports ±15V gate signal output, and has a drive current range of 0.5-2A (specific parameters need to be adjusted in combination with the application scenario).

Switching power conversion: Input 120V AC (±20%), 50/60Hz power supply, convert it into multiple DC voltages (such as 5V, ±15V), meet the power supply requirements of the gate drive and monitoring circuits, and the maximum power consumption is about 350VA.

Hardware Design Features

Fiber optic communication: DS200FGPAG1ALD achieves high-speed data transmission through 1 optical transmitter module and 14 optical receiver modules, with strong anti-electromagnetic interference capability and transmission delay ≤5μs.

Fault diagnosis: DS200FGPAG1ALD has built-in LED indicators to provide real-time feedback on power status, signal transmission and SCR faults (such as overvoltage, short circuit), supporting online diagnosis and rapid positioning.

Physical interface: Provides standardized wiring terminals (such as Euro-Block type), adapts to modular installation of industrial control cabinets, and supports hot-swap maintenance.

Gas turbine control: In power plants or industrial drive systems, turbine speed regulation and load distribution are achieved by precisely triggering SCR, supporting millisecond-level response.

High-voltage motor drive: Adapting LCI system for soft start and speed regulation of large motors, combined with SCR status monitoring to prevent overcurrent or overheating failures.

Energy and heavy industry: In petrochemical, metallurgical and other scenarios, closed-loop control is achieved with GE Speedtronic controllers, such as furnace temperature regulation or coordinated operation of pump groups.
