D-Frame VLT® Drives are up to 68% smaller than previous generation drives, and are optimized to deliver reliable performance in the 125-450 HP range while exhausting 90% of the drive-generated heat outside the enclosure via the backchannel. The product requires significantly less panel or wall space than previous models which were already among the smallest in their class. This reduces installation costs and increases installation flexibility. The product is available with IP20, IP21 (NEMA 1) or IP54 (NEMA 12) enclosure protection ratings. For robust protection, they also come standard with conformal coated printed circuit boards, which together with the optional heat sink access panel, help to extend drive lifetime and reliability.
