  • Single side maintenance reduces installation size.
  • Enhanced personnel safety due to mechanical and electrical blocking systems that exclude the possibility of electrical shock during operation or service of the drive.
  • High overload capability – 120 % in 120 s.
  • Has a variety of protection functions of the drive, the motor and the mechanical load.
  • Increased reliability due to the use of 6 power cells for each phase and cell bypass function.
  • Low harmonic distortion of the supply (THDi)
  • Inverter efficiency higher than 98 %, transformer efficiency higher than 98 % (for power higher than 1600 kW).
  • Optional operation only from medium voltage supply voltage, without the need for external low voltage supply.
  • V/F, speed or torque control options.
  • Cascade control of several motors.
