The MAST5-3C-U12 IGBT driver board is a 3-channel IGBT driver with a maximum output current of 5A per channel. The driver board uses AST965, has current source drive mode, reduces Miller effect time and switching loss in the same EMI conditions. Each channel has VCE detection short circuit protection, undervoltage protection, IGBT gate TVS protection elements, power indicator, and pulse indicator. Externally, only 12VDC (9-18V) or 24VDC (18-32V) power supply is required.
The MAST5‑3C‑U12 is a three‑channel IGBT driver board that provides 5 A per channel and up to 2500 VAC isolation. It supports 12 VDC (9‑18 V) or 24 VDC (18‑32 V) external power and includes built‑in TVS protection, short‑circuit protection, and signal interfaces for multiple control signals.
The manual describes the functional overview, mechanical dimensions, pin assignments, wiring diagrams, signal levels, protection signals, and recommended operating conditions. Safety precautions and installation tips are also provided to ensure reliable operation in high‑frequency (up to 20 kHz) applications. This manual is written in Chinese.
