Small Semiconductor Loop-Heater
LPS 164 | 10 W to 50 W

  • Clip fixing for quick mounting
  • Dynamic heating up through PTC technology
  • Wide voltage range
  • Additional approvals

Compact heater with PTC heating elements for heating enclosures with electrical or electronic components. The heater prevents too low temperatures and thus condensation harming the components. The design of the aluminium profile creates a chimney effect, which ensures even temperature distribution within the enclosure. The heaters are designed for continuous operation.
