Automation for a Changing World
Delta High Performance /
Standard Compact Drive
MH300 Series / MS300 Series
Compact and Intelligent
the new standard for Micro drives
The automation industry today continues to face challenges such as increasing competition and rising costs.
In addition to improving productivity and reducing labor, the driving force for automation is shifting to higher efciency,
optimal quality, and most importantly, exibility and compatibility for a wide range of applications.
Delta's MH300 and MS300 series are a new generation high performance and standard compact vector control drives
that inherit Delta’s superior drive technology—all in a compact drive that reduced 40% in size.
A variety of essential functions are built-in as standard, including: PLC capacity for simple programming needs, a
communication slot for various communication cards, 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.
Other key features include: Support for both IM and PM motor control for application exibility, an STO function
to ensure worry-free operation while protecting facilities from damage, and a simplied wiring process with a new
screwless wiring design of terminal blocks for quick installation.
Saving space, reducing setup and wiring time, and providing high efciency and stability system, the MH300 and
MS300 are your key to improving market competiveness and ensuring success.
