. . . . . Johnson Controls VSA35022NBA20C VSC Series III Variable Speed Micro Drive, IP20 575V 22A 20HP, Coated Circuit Board, FS2 Frame
The Johnson Controls® VSC & VSA Series III Variable Speed Micro Drives are both available in either a robust wall mount version (IP66) or a panel mount (IP20) version. The HP range extends to 30HP (480V), enabling design teams in to standardize on a single drive platform for powering and controlling all of their AC induction motors The integrated disconnect switch option on the IP66 version has the potential to lower installed costs in certain OEM applications (e.g., fan array) by eliminating the need for external branch circuit protection. Additionally, decentralized mounting of the IP66 drive(s) offers the opportunity to reduce the size of the remaining centralized control panel, furthering the potential cost savings. When centralized mounting of the drive(s) is the preferred design choice, the mechanical design of the IP20 model also delivers panel size reduction opportunities. First, there is the physical compactness of the drive itself. The 5HP is less than 5" wide, and the 15HP is less than 6" wide. Further contributing, is the permissible zero gap side by side mounting, and DIN rail mounting capability (FS1 and FS2). Finally the contractor style wiring minimizes the potential for miswiring, while streamlining the panel layout.. Johnson Controls. Johnson Controls. VSA35022NBA20C.
