REOTRON MDW 700
REOTRON MDW series, three-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. In the phase-angle mode the unit works as a regulator for RMS current, RMS voltage, or real power. The proportional regulation
adjustment is variable.
External setpoint signals can be used for controlling current, voltage and power, or potentiometers may be used instead. A serial RS232 or CANBUS, Device-Net, PROFIBUS-DP or EtherCat 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.
Additional fan-assisted cooling is provided on units with current ratings higher than 50 A.
