ABSTRACT:
Subject-matter of the invention is an overload protection and display circuit, in particular for operation in conjunction with high-power sound radiators, and including one or more protective circuits therein. Each circuit senses the real value of the electrical sign applied to their inputs. The moment of interference depends on the averaged real output of an adequately long memory period preceding the interference. Consequently the sound radiators may be operated controlled by an output considerably in excess of the usual.
Improved results are achieved by connecting an indirectly heated thermistor in series with the winding of an interfering relay, and using a Zener diode connected for operation in the reverse direction, while the filament windings of the indirectly heated thermistor are terminated on the input points of the protective circuit through a resistance.
