REOTRON MEW 700

Thyristor controller

REOTRON MEW 700

Unique Selling Point


  • Current, voltage or power control
  • Switchable for phase-angle or burst-fire control up to 300 A
  • With integrated semiconductor fuses
  • Interfaces: RS232, Profibus
  • Internal setpoint adjustment using display, external with potentiometer
  • Effective value feedback: current voltage or power

Description


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 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 theThe proportional regulation.
 
Applications:
  • Industrial ovens
  • Steam generators
  • Lighting systems
  • Infra-red dryers
  • Pre-heating equipment
  • Heating and ventilating equipment 
  • Heating tunnels
