MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200FHVAG2A DS200FHVAG2ADA High Voltage Gate Interface Board translates low-level gate commands for high-power devices. This board interfaces between the main controller and HV IGBT or GTO modules. You will find it providing electrical isolation between logic and power circuits. It ensures safe and reliable gate signal transmission at elevated potentials.
Core Technical Specifications
The GE DS200FHVAG2A DS200FHVAG2ADA High Voltage Gate Interface Board measures 22.0 cm in width and 16.0 cm in height. Its board depth equals 2.5 cm including isolation transformers. The total assembly weighs approximately 0.48 kilograms. Six independent gate interface channels populate the board’s surface. Each channel provides galvanic isolation up to 1500 Vrms.

Connectors and Signal Routing
The GE DS200FHVAG2A DS200FHVAG2ADA High Voltage Gate Interface Board uses six fiber optic receivers for input isolation. These receivers accept TTL-level light pulses from the main controller. Six 2-pin headers provide gate and emitter connections to power modules. A 9-pin D-sub connector carries status feedback signals back to the controller. Additionally, the board includes one 4-pin header for auxiliary 24 VDC power.
Protection and Diagnostic Features
This interface board includes undervoltage lockout protection on every output channel. The board prevents operation when supply voltage falls below acceptable levels. Moreover, the GE DS200FHVAG2A DS200FHVAG2ADA High Voltage Gate Interface Board integrates short circuit protection on gate outputs. Six green LEDs confirm proper input signal reception on each channel. A red LED illuminates undervoltage or gate fault condition. The board also provides a common fault relay output.
Energy Storage and Isolation
This interface board contains small ceramic capacitors only on the power input. Therefore, it stores negligible residual energy after power removal. The GE DS200FHVAG2A DS200FHVAG2ADA High Voltage Gate Interface Board uses pulse transformers for channel isolation. These transformers provide excellent common mode transient immunity. Operate the board from 0°C to +60°C ambient temperature. Do not exceed the maximum isolation voltage rating. Keep gate leads under 0.5 meters for best performance.
