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.
