PTC HEATING DEVICE WITHOUT ELECTRONIC POWER CONTROL

Foil-based PTC heaters are self-regulating, i.e. do not need any electronic control unit (ECU) to limit the maximum heating current. In order to establish different heating power levels the present invention proposes to choose different PTC ratio / onset characteristics. In addition, the print desig...

Beschreibung
Zusammenfassung:	Foil-based PTC heaters are self-regulating, i.e. do not need any electronic control unit (ECU) to limit the maximum heating current. In order to establish different heating power levels the present invention proposes to choose different PTC ratio / onset characteristics. In addition, the print design of the PTC ink can be adjusted accordingly. L'invention concerne des dispositifs de chauffage PTC en feuilles métalliques à auto-régulation, c'est-à-dire qu'ils ne nécessitent aucune unité de commande électronique (ECU) pour limiter le courant de chauffage maximal. Afin d'établir différents niveaux de puissance de chauffage, la présente invention propose de choisir différents ratios PTC/caractéristiques d'amorçage. De plus, le dessin d'impression de l'encre PTC peut être ajusté en conséquence.
