MH300 Series

MS300_MDelta’s MH300 series are a new generation high performance vector control compact drives that inherit Delta’s superior drive technology. It provides outstanding drive performance with high starting torque control nd fast response to load changes. It is also a strong and highly flexible system that features multi-motors control, closed loop control, various fieldbus and I/O expansion possibility.

A variety of essential functions are built-in as standard, including: support for both IM and PM motor control, STO function, PLC, and a USB port to make data uploads and downloads fast and easy. This saves the need for additional hardware, while providing more installation space for the power cabinet. MH300 is your key to improving market competiveness and ensuring success.
