self limiting elsr n

A temperature-dependant resistive element between two parallel copper conductors regulates and limits the power output of the heating tape. This output regulation is carried out automatically along the entire length of the heating tape according to the prevailing ambient temperature. If the ambient temperature rises, the power output of the tape is reduced. This self-limiting property prevents overheating even when the tapes are crossed. Thanks to the parallel design the heating tape can be cut to any required length. This feature considerably simplifies project planning and installation. The heating tape is cut and terminated directly on the construction site according to the circumstances. The heating system must be designed to ensure that the maximum operating temperature of 65 °C will not be exceeded when it is energized. When it is switched off, the heating tape can be exposed to a temperature of 85 °C, not more than 1,000 hours cumulated.
