  • Improved bandwidth response for elimination of outside interference.

  • Increased sensitivity for better fault detection

  • Lower current consumption through the use of integrated circuits.

  • 60Hz filter provides high AC inductance rejection with at least 34dB of isolation to AC harmonics at 540 hz.
