The converters have evolved from the earlier Dynavert T family. They are aimed at applications such as pumps, fans, compressors, conveyors, mixers and extruders.
Combining the Atex-certified temperature monitoring with a built-in Safe Torque Off function allows the converters to control explosion-proof motors without needing a line contactor. Evaluation is performed using a PTC thermistor embedded in the motor windings.
The built-in dV/dT filter supports cable runs of up to 350m long between the converter and the motor. The drives can be dimensioned using Siemens’ Sizer and DT Configurator engineering tools.
