PTC Heater
HGK 047| 10 - 30 W

  • Compact size
  • Wide voltage range
  • Heating power adjusts to ambient temperature
  • DIN rail mountable

The HGK 047 heaters are used in enclosures to maintain minimum operating temperatures and to help prevent failure of electronic components caused by condensation and corrosion. They are suitable for permanent operation.
