IS heater - Heater with electronic relays

The IS (integrated switch) heater represents a cost-effective and commercial solution for electronic PTC heater elements. The electronic activation is restricted to the switching of individual heating circuits via electronic power switches integrated into heating element.

Compared to actuation with mechanical relays, electronic relays stand out thanks to their silent switching of the heating circuits and a considerably longer service life.
