High-power platform for VLT 5000 Series, VLT 4000 Series, VLT 6000 HVAC Series, and VLT 8000 Aqua Series variable-frequency drives (VFDs) replaces three of the largest units in the 380-500 V ac range in each series and adds an additional higher power unit to the program. Intended for full constant or variable torque demands of virtually any industrial process, water, or HVAC application, the drives offer up to 550 hp from VLT 5000 and up to 650 hp from the other VLT series. These VFDs are said to offer reliable, accurate operation at 98% efficiency, resulting in a significant reduction in heat dissipation. Drives are available with three enclosures: Chassis/IP00, NEMA/UL type 1/IP21, and NEMA/UL type 12/IP54. Modular construction allows purchase of only what is needed; operating software and options facilitate retrofits. www.namc.danfoss.com Danfoss North America Motion Controls
