Input received through input rectifier is connected via an intermediate circuit to a converter that generates a square wave voltage to drive a motor. The intermediate circuit PTC resistor (200) has a voltage load limit of 600V and a holder (205) with upper...

The positive temperature coefficient heating device has a housing containing at least one positive temperature coefficient element (4) held in contact with at least one contact plate (6,8) via a spring element (9,10). The housing has at least one retaining...
