3.2 Regulation mode
The REOTRON MDW Thyristor Regulator range include 3 regulators, ie. voltage, current and power
regulator. All the regulators always work in combination, ie. with voltage regulation for example, the cur-
rent regulation operates like a cascade control and limits the output current in case of overload on the
rated current. In case of current regulation mode, the maximum voltage limit can be prescribed over the
voltage set point. With power regulation, the current limit is also effective as cascade.
In case both the voltage and current regulation are used, the set point of the power regulator must be set
to 100 % (over display, in menu „C 002“, parameter „P“).
Voltage regulation
Microprocessor controller with PI Characteristics; the P portion is adjustable externally by using the key-
Pad. The units maximum voltage output is factory set to the rated voltage (for 100% set point).

Current regulation

Pad. The units maximum output current (Rated Current) is factory set.

Power regulation
With power regulation, the real power value is controlled. In this case, the input that is normally coordi-
nated to the voltage set point is now used as set point input. This set point input corresponds to 0...100
% of the unit output power. The current set point must be set to 100 % or to the required limit value. Set-
ting over display or link between terminals 7 and 8.
