Zusammenfassung:A power supply for the heater cathode (K) in the multiplex cycle is proposed which makes corresponding use of the thermal time constant of the heating filament. The multiplex cycle provided for operating a four-position numerical display (1) is extended by an interval within which for heating purposes voltage pulses are connected to the cathode (K) separately from the numerical control. Envisaged application: central power supply of electronic box in multistorey car parks.
