Abstract
Disclosed is a method for controlling a series circuit current of a lighting installation at an airfield or the like, in which case the series circuit current which flows through transformers which are arranged on the secondary side of an output transformer and are connected in series, in order to supply lighting appliances is controlled by means of a thyristor module, which is arranged on the primary side of the output transformer and has a variable trigger angle, in which case, when a control unit is in a constant-current mode, the trigger angle is set in such a manner that a series circuit current which corresponds essentially to a rated output current flows. The invention also relates to a constant-current regulator for carrying out the method.
