In addition to the IP20 devices, an IP66-rated version of the DC1 is also available for applications up to 22 kW. Therefore, using the devices in moist, dusty or contaminated environments poses no problem at all. Thanks to the waterproof ABS housing and the corrosion-resistant heat sink, the devices are suitable for use in the food industry, in agriculture or in vehicle wash systems. The IP66 devices are optionally available with local control elements. These elements feature an integrated setpoint potentiometer as well as selector switch and a main switch, and enable the configuration of the DC1 drives directly on site.
