Document Type and Number:
Japanese Patent JPH0652492
Kind Code:
B2
Abstract:
A mains-voltage discrimination device for adapting a load (8) to a lower or higher alternating-voltage range is described. Discrimination is effected by means of a voltage-dependent resistor (1) which is thermally coupled to a PTC-resistor (2) which is electrically arranged in series with said voltage-dependent resistor (1), the resistors (1, 2) being chosen so that initially the dissipation is mainly determined by the voltage-dependent resistor (1).
