The frequency converters of the ESN series provide smooth start, smooth braking and speed control of asynchronous electric motors with a closed rotor and synchronous electric motors with a voltage of 3, 6, 10 kV in technological processes, reducing energy costs, wear of electric motors and rotating mechanisms.

The transformer-free frequency converter of the EMSN series is designed to regulate the rotational speed of asynchronous and synchronous high-voltage electric motors with a rated voltage of 3...10 kV and a power from 160 kW to 8 MW.

SHPTU-VIR is a two-link thyristor frequency converter made according to the topology of a dependent current inverter (LCI). The frequency converters of the SHPTU-VIR series are designed for frequency start-up, braking and speed control of synchronous machines with a voltage from 3 kV to 15.75 kV with a capacity of up to 100 MW, reducing energy costs, wear of electric motors and rotating mechanisms.

The ANN series frequency converters provide smooth start-up, smooth braking and speed control of 0.4 - 0.69 kV electric motors in technological processes, reducing energy costs, wear of motors and rotating mechanisms.
