MAST5-7C-U12 type IGBT driver board is a 7-channel IGBT driver board with AST965, each channel driving current is 5A. It has 7 isolated DC-DCs with a 2500VAC isolation voltage. The current source driving mode reduces the Miller effect time and switching loss in the same EMI conditions. Each channel has short-circuit protection with VCE detection mode. Each channel has undervoltage protection. Each channel has IGBT gate TVS protection elements. Each channel has power indication and pulse indication. The flat line signal interface is concentrated and supports multiple input levels. Only 1 power supply 12VDC (9-18V) or 24VDC (18-32V) is required externally.
This manual describes the MAST5‑7C‑U12 IGBT drive board, a 7‑channel IGBT module with integrated protection and configurable voltage levels. It outlines the functional features, dimensions, pin assignments, and signal interfaces for both 12 V and 24 V power supplies.
The document includes detailed wiring diagrams, protection signal definitions, power‑source parameters, error‑output behavior, and a full set of electrical specifications. Precautions for installation and thermal management are also provided. This manual is written in Chinese.
| VDD‑VSS (24 V) voltage range | 18‑32 V |
|---|---|
| VDD‑VSS (12 V) voltage range | 9‑18 V |
