MAST5-4C-U17 IGBT driver board is a 4-channel IGBT driver board using AST965, each channel with a driving current of 5A, 4 mutually isolated DC-DCs, isolation voltage 3500VAC, current source drive mode, reduce Miller effect time and switching loss under the same EMI conditions, each with VCE short-circuit protection, undervoltage protection, IGBT gate TVS protection elements, each with power indicator and pulse indicator, a concentrated flat line signal interface, supports multiple input levels, and only needs to input 12VDC (9-18V) or 24VDC (18-32V) of power for the driver board.
