About product
Premium solution for powerful motors
Variable Frequency Drive Triol AT24 line SD is a premium solution for powerful motors. Floor mounting for easy installation. Triol AT24 VFD line SD is a low-width and high cabinet with module design and a wide range of built-in options. Removable power cell of high-power Triol AT24 VFD line SD allows performing repair work without dismantling the entire cabinet. A convenient and elaborate system for lifting power cells allows easy installation. Easily removable air filters allow performing periodic maintenance in minutes without stopping and disconnecting supply voltage from Triol AT24 VFD line SD. IP54 enclosure is optional.
Wide range of application
The Master-Slave drive application is available for Triol AT24 VFD line SD for operation in multi-motor systems. For powers 500..800 kW (680…1080 HP) at 380/480 V and 1000..1600 kW (1360…2175 HP) at 690 V, a parallel connection of two Triol AT24 VFD line SD is used. Triol AT24 VFD line SD is optionally equipped with a removable wireless control graphic terminal with induction supply. It is possible to control several VFDs. AT24 SD is designed to control pumps, HVAC systems, exhausters, compressors, conveyors, crushers, mixers, grinders, mills, rolling mills, drilling rigs.
Various additional units
Setting up and controlling the AT24 SD is easy due to the use of: Wi-Fi adapter with step-by-step Triol Wizard via smartphone, service software Triol Drive for PC, remote control terminal with transient graphs. Various additional units for VFD control system extend abilities of process control.
