Low and high voltage electrical heating devices

   
   

A low-voltage self-regulating heating device (200) for operation with supply voltages in the range of 0.1-12 volts having first and second layers (104, 106) of material, at least one of which is PTC material interposed between a first electrode (102) and a second electrode (108). Also a high-voltage self-regulating heating device (300) for operation with supply voltages above 240 volts having first and second layers (104, 106) of material, at least one of which is PTC material interposed between a first electrode (102) and a second electrode (108).

Um dispositivo de heating self-regulating low-voltage (200) para a operação com as tensões de fonte na escala de 0.1-12 volt que têm primeiramente e de segundas camadas (104, 106) de material, ao menos um de que é material do PTC interposed entre um primeiro elétrodo (102) e um segundo elétrodo (108). Também um dispositivo de heating self-regulating de alta tensão (300) para a operação com as tensões de fonte acima de 240 volts que têm primeiramente e de segundas camadas (104, 106) de material, ao menos um de que é material do PTC interposed entre um primeiro elétrodo (102) e um segundo elétrodo (108).
