The power supply may be used to power a device or charge a battery for a device that requires a low voltage input. The power supply may be used in underground vaults and pad mounted chambers that contain high voltage power lines. The power supply may generate a low voltage direct current out put that is not available in the vicinity of high voltage power lines in an underground vault or pad mounted chamber.

Why it's free to use

  • Filed March 10, 2006 and granted December 30, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 10, 2026.
  • Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
