Schneider VX5A1HC2025 Inverter Power Board

Feature & Principle

It is Schneider ATV61 / ATV71 series high-power inverter dedicated power drive board. It converts DC bus voltage into multi-channel isolated power for IGBT drive circuit, provides gate pulse signal and fault detection function. It integrates sampling, rectification, protection circuit, monitors voltage and current status in real time. When overcurrent, short circuit and drive abnormality occur, it quickly triggers protection to avoid IGBT damage. It is a core spare part for 200kW and 250kW models, widely used for maintenance replacement of old frequency converters.
