Frequency converters «VARIANT» (power from 450 to 3600 kW at voltage of 690 V) are designed for control of three-phase synchronous and asynchronous motors used in processing plants in various industry sectors: water treatment, supply and discharge, oil and gas industry, metallurgy and mining industry.
The converters feature a rich hardware and software suite. The drives «Variant» include the draw-out rectifier and inverter modules with power connectors, providing for ease of maintenance and redundancy owing to the use of modules connected in parallel. If one module becomes faulty, then, when it is off, the drive can continue operating underpowered.
