HVAC variable speed drives from Siemens control the energy demand of equipment with high power consumption in a highly efficient way. Fans and pumps use up to 50% less energy thanks to these SED2 variable speed drives: especially thanks to the precise, on-demand control of the motor speed. In addition, the Low Harmonic Technology of the SED2 devices reduces mains harmonics to a minimum.

Based on Siemens’ decades of experience, SED2 enable simple, cost-efficient commissioning and maintenance. Thanks to the comfortable commissioning assistant and the library with easy adaptable applications, the devices are ready for use quickly and error-free. During maintenance, the modular design and free accessibility make the exchange of single components easy.
