GPD 315 Open Loop Vector AC Drive, 1/8 - 5 HP MagneTek's GPD 315 is a high performance AC drive which produces an output of adjustable voltage and frequency to control the speed of squirrel cage induction motors. By the use of IGBT transistors and high carrier frequency, this PWM design provides low motor noise and high starting torque. The current overload rating is 150% for 60 seconds. The GPD 315 provides two control methods; V/Hz and open loop vector control to suit precise speed re...

GPD 333 General Purpose AC Drive 1/4 - 5 HP The GPD 333 is 1/4 the size of conventional PWM drives, while providing more programming capability. The drive is available in 230 and 460 VAC ratings, and is NEMA 1/12 enclosed. The NEMA 1 enclosed version is also available in an optional NEMA 12 enclosure. A 16-bit microprocessor handles all logic functions, as well as the complex, sine-coded PWM-generating algorithms that control IGBT switching. The GPD 333 provides the benefits of all-...

GPD 515 General Purpose AC-Drive 3/4 - 500 HP 50 Years of AC Drive Technology Fifty years ago, MagneTek provided adjustable frequency drives in the form of variable-speed-driven alternators. In the ë60s, MagneTek introduced solid-state thyristor inverters to replace the alternator, significantly reducing the cost of adjustable frequency drives. In the early '70s, we introduced the first commercially-available Current Source AC drive. Although there was a price premium, AC drive p...
