Simple speed controlling of fans and pumps

The speed controllers from DOLD especially serve the simple speed controlling of pumps and fans to adjust the load on the drive machine. In comparison to frequency converters, they provide with substantially few EMC problems because no shielded wires are necessary. Possible applications are the speed controlling of exhaust fans for large kitchens.
