Thyristor Controllers
REO builds a wide range of single and three phase thyristor controllers that work on the phase-angle control principle. These are used for voltage, current or power regulation applications. The largest stand-alone unit, produced so far, is water cooled and is rated for 3 x 450A. Even larger regulators can be built by using the REOTRON MDZ 6-pulse controller in conjunction with a thyristor stack.
REOTRON MDW Thyristor Controllers ......................................................................................
The MDW range of controllers are designed for regulating a three phase supply, using the phase-angle control principle. There are a number of versions available and choice depends upon the preferred method of control. The simplest units are used in conjunction with potentiometers or analog signals that provide the set point to give voltage, current or power regulation. Microprocessor control provides more functions for customising, through a digital front panel and also the ability to operate from standard field bus systems such as Interbus or Profibus.

REOTRON MEW 2S Thyristor Controller ......................................................................................
The MEW 2S thyristor controller is designed to work in conjunction with a special load transformer. It generates two voltage levels; an underlying low-level full-wave output and a variable phase-angle controlled adjustable output. This technique offers a number of advantages; mains disturbances are minimised, pfc improved, current draw is reduced and the process is usually a lot more stable. The unit can operate in power regulation mode and can be fitted with a serial bus interface as an option. |
