Opto-Isolated BLDC Driver Module

Introduction to AT10

AT10 combines the precision and performance of our FPGA based Snō module with 10 channels of optically-isolated digital I/O to resulting in a compact controller capable of reliably driving IGBTs in high-power brushless DC motor systems and providing the following key benefits:


Noise Immunity


High-Voltage Compatibility

The control logic hardware is configurable which makes AT10 easily customizable for unique motor control applications.

Benefits of Optical Isolation

Noise Immunity

Opto-isolators prevent voltage spikes and other electrical noise common to high-voltage systems from reachin control electronics.

High-Voltage Compatibility

Opto-isolators provide electrical compatibility between control electronics and high-voltage motor subsystems.
