Why Choose the Omron 3G3IV-PFO-OC/2 Output Filter Choke?

The Omron 3G3IV-PFO-OC/2 is a dedicated output cable filter choke designed for use with Omron SYSDRIVE 3G3IV variable frequency drives. It helps reduce high-frequency electrical noise, improve motor cable performance and support reliable operation of inverter-driven motor systems.

Designed for industrial automation applications, the 3G3IV-PFO-OC/2 provides effective suppression of electromagnetic interference (EMI) and radio frequency interference (RFI) generated by inverter outputs. This makes it suitable for installations where long motor cables, sensitive equipment or strict electrical noise requirements are present.

The Omron 3G3IV-PFO-OC/2 ferrite choke features a compact through-hole design with an approximately 28.5 mm central opening and is typically used with single-phase drives up to 3.7 kW and three-phase drives up to approximately 1.5 kW.

Key Advantages

  • Dedicated output filter choke for Omron inverter systems.
  • Reduces electrical noise from variable frequency drive outputs.
  • Improves EMC performance in industrial installations.
  • Helps protect sensitive equipment from inverter-generated interference.
  • Compact ferrite core design for simple installation.
  • Compatible with Omron SYSDRIVE 3G3IV inverter applications.

Key Features

  • Omron 3G3IV-PFO-OC/2 output cable filter choke.
  • Designed for inverter output noise suppression.
  • 28.5 mm central hole diameter.
  • Ferrite choke construction.
  • Suitable for motor drive applications.
  • Supports improved electromagnetic compatibility.
  • Simple cable-through mounting arrangement.

Reliable EMC Performance for Motor Drive Systems

Output chokes such as the Omron 3G3IV-PFO-OC/2 are used between variable frequency drives and motors to reduce voltage spikes, electrical noise and interference caused by fast switching inverter technology. This helps improve system reliability and protects connected motor equipment.

The filter choke is especially useful in industrial environments where inverter operation may affect nearby control equipment, communication systems or instrumentation. By improving output waveform characteristics, it supports smoother and more dependable motor drive performance.

Typical Applications

  • Industrial automation systems.
  • Variable frequency drive installations.
  • Motor control panels.
  • Production machinery.
  • Pumps and fan systems.
  • OEM equipment requiring EMC noise reduction.
