The multifunctional motor control devices from DOLD in the MINISTART family offer a combination of functions for motor control such as revering or soft start with monitoring functions such as the effective power or current monitoring. The ready-to-use devices with optimised parameters such as heat sink size, EMC, heat dissipation, et cetera are easy to use. Benefits such as low material costs, fast device connection and reduced space and wiring needs are on the plus side of these intelligent devices. In addition, they often prevent the need for a frequency converter.
