Single-phase Thyristor Controller Reotron Mew 700

Single-Phase Thyristor Controller


REOTRON MEW series, single-phase, microprocessor-based, thyristor-controllers are suitable for resistive or resistive/inductive loads, especially those with a high Rcold / Rwarm coefficient. Status relays indicate unit ready and fault conditions. Depending on the settings, the controller normally operates on the phase-angle principle (standard setting). It can also be used in a burst-fire mode. Phase-angle mode the unit works as a regulator for RMS current, RMS voltage or power. Adjustment is variable.

External setpoint signals can be used for controlling current, voltage and power or potentiometers may be used instead. A serial RS232, PROFIBUS-DP field bus
interface can be used for remote adjustment. All unit settings can be made through the controller’s front panel, using a LED display and keypad In the proportional regulation.


  • Operation via LED display and buttons
  • switchable between phase-angle or full-wave cycle operation
  • Integrated semiconductor fuses
  • Current, voltage or power control
  • Interfaces: DeviceNet, ProfiBus, CanBus, EtherCAT, EtherNet / IP and ProfiNet (optional)
  • Actual value feedback: current, voltage or power
