Estel Electric Drives - Brochure

Estel-Drive is a family of high voltage frequency converters (HVFC) for asynchronous and synchronous AC motors. The HVFC Estel-Drive is made on the basis of IGBT (insulated-gate bipolar transistors) and meets the highest international standards as regards the harmonic distortions of current and voltage, both at the input and output of the frequency converter. Estel-Drive frequency converters automatically maintain the operational parameters of machine assemblies at the required levels in accordance with the pre-set modes of operation of technological equipment, preventing the excessive power consumption from the supply network and reducing the losses in motors due to the decrease of their loads.
