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.
This manual describes the functions, wiring, and signal interfaces of the MAST5-4C-U17 IGBT drive board. It includes the layout of the four IGBT channels, isolation requirements, and external power connections.
The document also lists technical specifications such as current limits, isolation voltage, operating temperature, and recommended supply voltages, along with safety and installation notes for reliable operation. This manual is written in Chinese.
