The REOTRON EW 514 is a single-phase thyristor power regulator for load currents up to 6 A.
The control electronics are isolated from the mains voltage. The REOVIB 509 is designed for controlling bowl or linear feeders up to 15 A current rating. The output frequency 50Hz/100Hz (60Hz/120Hz) is selected to suit the feeder. In the regulation circuit there is built-in compensation for mains variations.
