Semiconductor Loop-Heater
LP 165 | 60 W to 150 W

  • Clip fixing and pressure clamp 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 practical push-in clamping terminal ensures quick and easy electrical connection. The heaters are designed for continuous operation.
