Triol AT27 VFD, 6 kV, maximum output voltage 3-6 kV, cabinet-type

Triol АТ27-6kV cabinet-type variable-frequency drive is designed to control cage asynchronous and synchronous motors as well as synchronous motors with external exciter. Compact and ergonomic design provides an opportunity to comfortably adapt the product to the service conditions prevailing at a particular Customer’s facility. Triol AT27 control system makes it possible to readily integrate a variable-frequency drive into the manufacturing process. Triol IDrive technology used therein opens up new opportunities associated with remote control and adjustment.

  • 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.
