摘 要：
An electrical direct heating device
embodied as a surface heating device, comprising at least one first electrical connection element (10), at least one second electrical connection element (12), wherein the connection elements (10, 12) are electrically conductively
connected or connectable to an electrical power supply device (2), at least one between the at least two connecting elements (10, 12) extending electrical heating element (14) and an electrical control device (3) is characterized in that the control device (3) has a modulation device (30) which is formed so that they generates a modulated voltage signal for the electrical voltage applied to the connection elements (10, 12) or
modulates the current intensity of the electric current flow from the power supply device (2) to the connection elements (10, 12), and that a frequency variation device (32) is provided, which trained i st, that it varies the modulation frequency (F) of the voltage signal or the
