MINISTART - Intelligent, flexible and high-performance!

DOLD soft start devices of the MINISTART family ensure that your machines start up gently and smoothly and/or minimise a wide variety of problems such as mechanical wear during the direct start of drives, the tipping or sliding of loads on transport belts, pressure surges in the lines of pump systems and much more. They reduce the wear on and increase the service life of your motors and mechanical drive components. DOLD soft start devices offer additional advantages as a simple and space-saving installation, provide flexible configuration options and relieve the supplying grid through reduced starting current.
