MagneTek's microsize GPD 205 adjustable frequency drives are now available in 460V ac models. The new models come in four incremental ratings from 0.5 to 3 hp. Although only a fraction of the size of conventional PWM drives, the GPD 205 is said to be useful for sophisticated equipment control in applications that include fans, pumps, mixers, agitators, compressors, conveyors, commercial laundry, and material-handling installations. The drive's 16-bit microprocessor provides the flexibility, features, and performance for a wide range of operational requirements. It installs and programs easily, has the versatility to adapt to simple or complex applications, and is UL-listed, CSA-approved, and CE-marked. MagneTek Drives & Systems. Product Code 4361
University of Southampton researchers have come up with a way to 3D print transparent optical fibers like those used in fiber-optic telecommunications cables, potentially boosting frequency and reducing loss.
