ABSTRACT:
A device for regulating the current in a load includes a voltage-frequency converter for direct proportionally converting a voltage proportional to the load current into a number of pulses per time unit; a counter and a memory with a corresponding indicator for repetitively storing and displaying a number of pulses counted during a measuring interval; a nominal value control with corresponding indicator, a limit value control, and a comparator and a regulating unit by which the memory contents corresponding to said measuring interval are continuously compared with the lower limit and upper limit value superimposed on the nominal value such that upon exceeding one of these limit values the voltage for the load is adjusted.
