Delta RF008X00A Zero Phase Reactor

  • Zero-phase reactors reduce inverter wiring noise.
  • Wiring passes through the reactor to filter RF noise.
  • Loop wires three times for full filtering.
  • Use up to four reactors for larger wires.
  • Filters reduce noise on input/output sides.
  • Effective from AM band to 10 MHz.


Zero-phase reactors, also known as RF noise filters, help minimize radiated noise from inverter wiring. To reduce the RF component of electrical noise, the wiring must pass through the reactor’s opening. Loop the wires three times (four turns) to achieve full RF filtering. For larger wire sizes, multiple zero-phase reactors (up to four) can be placed side by side for enhanced filtering. These filters are effective at reducing noise on both the input and output sides of the inverter, with good attenuation across a broad frequency range from the AM band to 10 MHz.
