MAST5-7A type IGBT driver board is a 7-channel IGBT driver with AST965, each driving current is 5A, with 7 mutually isolated DC-DC, isolation voltage 3000VAC, current source driving mode, in the same EMI conditions, reduce Miller effect time, reduce switching loss.
The MAST5-7A driver board provides seven isolated IGBT driver channels with 5 A per channel, built‑in short‑circuit, undervoltage and gate‑TVS protection, and supports 12 V or 24 V DC power input. The manual details the functional description, hardware layout, pin assignments and wiring diagrams.
Installation, signal input requirements, protection signal outputs, power supply connections and recommended operating conditions are covered, along with adjustment of short‑circuit protection timing and thermal considerations for reliable operation in industrial control applications. This manual is written in Chinese.

The board provides seven isolated IGBT driver channels.
It can be powered from a single 12 VDC (9‑18 V) or 24 VDC (18‑32 V) supply.
Each channel has VCE‑detected short‑circuit protection, undervoltage protection, and IGBT gate TVS protection.
The board is rated for ambient temperatures from –25 °C to +70 °C.
