Regulated 1-Phase Thyristor-Controller

REOTRON MEW – The single-phase thyristor power controller

Single-phase thyristor power controllers are predestined for applications in process industries, in particular in thermal plants.

The thyristor controllers can work in phase angle control or in periodic group control operating mode and possess an internal voltage, current and power controller.

  • REOTRON MEW 700

    Thyristor controller

    REOTRON MEW
    • Input voltage: 230 / 400 V AC +/-10 %
    • Output voltage: 0...Ue V
    • Output Current: max. 300 A
    • Input voltage switchable: 230 - 400 V
    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, CAN-Bus and DeviceNet-DN  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.

     


    Applications:



    • Industrial ovens

    • Steam generators

    • Lighting systems

    • Infra-red dryers

    • Pre-heating equipment

    • Heating and ventilating equipment 

    • Heating tunnels



  • REOTRON EW 514

    Single-phase thyristor power regulator

    ttt
    • Input voltage: 230 V + 6% / - 10%
    • Output voltage: 0...230 V
    • Output Current: 6 A or 8 A
    • Input voltage switchable: Eingangsspannung umschaltbar [V] V

    The REOTRON EW 514 is a single-phase thyristor power regulator for load currents up to 6 A or 8 A.

    The control electronics are isolated from the mains voltage. Load power is controlled by means of thyristors operated in the phase-angle control mode. The setpoint signal can be provided either by a potentiometer, or by a 0…+ 10 VDC or a 0(4)…20 mA control signal. Matching of load power to the required setpoint range is affected by internal trimmer potentiometers for Umin/Umax. Remote control of the unit is possible by means of an enable/inhibit input.
    Variation of the mains supply is compensated by an internal control circuit.

    The unit is mounted to a 35 mm rail to DIN EN 50 022.

    • Output Current: 15 A
    • Protection: IP20
    • Input voltage switchable: . V
    REOTRON EW 509 is a singlephase thyristor power regulator for load currents up to 15 A.
