Toshiba MTX NEMA 3R MV Severe Outdoor Drive

Toshiba proudly introduces the MTX NEMA 3R Outdoor Medium Voltage ASD. The MTX is the world’s first ASD specifically designed for outdoor mounting in remote applications or applications where a building does not exist. It features an innovative enclosure design and power section topology that is unprecedented in the medium voltage ASD arena. The MTX is two enclosure types married together. The transformer section is convection cooled. There are no moving parts, and heat is eliminated through passive vents at the top of the drive. The inverter section is forced cooled. Power modules are designed with the heat sinks out-the-back to send waste heat to the atmosphere. The interior of the inverter section is cooled using plate-type heat exchanger(s) so it remains cool and clean without introducing outside air. The new topology is a logical progression of the proven T300MVi design in a UL Raintight enclosure. Additionally, you will achieve a lower cost of ownership with the MTX because heat removal from a building-based drive is eliminated.
