MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200FHVAG1A DS200FHVAG1ADA High Voltage Gate Interface Board translates low-voltage logic signals into high-side gate commands. This board interfaces directly between the main controller and HV IGBT modules. You will find it providing critical electrical isolation between logic and power circuits. It ensures reliable gate signal transmission at elevated DC bus potentials.
Core Technical Specifications

Connectors and Signal Routing
The GE DS200FHVAG1A DS200FHVAG1ADA High Voltage Gate Interface Board uses four fiber optic receivers for isolated input signals. These receivers accept TTL-level light pulses from the main controller board. Four 2-pin headers provide gate and emitter connections to IGBT 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 input.
Protection and Diagnostic Features
This interface board includes undervoltage lockout protection on every output channel. The board prevents IGBT operation when supply voltage falls below safe limits. Moreover, the GE DS200FHVAG1A DS200FHVAG1ADA High Voltage Gate Interface Board integrates short circuit protection on all gate outputs. Four green LEDs confirm proper input signal reception on each active channel. A red LED illuminates during an undervoltage or gate fault condition. The board also provides a common fault relay output for system monitoring.
Energy Storage and Isolation
This interface board contains small ceramic capacitors only on the power input stage. Therefore, it stores negligible residual energy after power removal. The GE DS200FHVAG1A DS200FHVAG1ADA High Voltage Gate Interface Board uses pulse transformers for all channel isolation. These transformers provide excellent common mode transient immunity performance. Operate the board from 0°C to +60°C ambient temperature only. Do not exceed the maximum isolation voltage rating under any condition. Keep gate lead lengths under 0.5 meters for best switching performance.
