The motor controllers of SMC-500 SERIES are multi-functional high-performance products that are to be easily used wherever the Motor Operating is needed. These Series satisfy the various international standards and adopt the standardized circuits and the control circuits are composed of international standardized parts selected rigidly.
As special features, the exterior materials have high insulation level, light weight, fire retardant, shock resistant and chemical resistant characteristics to endure the harsh environment such as shipyard, power plant, steelworks, petrochemical complex and water power plant etc.. These have IP65 grade.
