About product
Wide range of application
Modular Variable Frequency Drive Triol AT24 line MP is designed for controlling multi-motor systems that are used on powerful industrial plants, such as conveyors, rolling mills, drilling rigs, developed in compact dimensions.
Enhanceed enclosure
Triol AT24 VFD line MP basic configuration is IP21 enclosure. It is possible to advance Triol AT24 VFD line MP to IP54 enclosure with external air filter that is designed according to unique technology for successful operation in certain environmental conditions if requested. Triol AT24 VFD line MP consists of three separate modules, where each module has its own control system: rectifier cabinet (thyristor\diode or active), inverter cabinet, brake unit cabinet
