Omron 3G3IV-PFO-OC/2 output cable filter choke for inverter motor control systems, designed to help suppress EMI, RFI and electrical noise on motor output cables.
Original price was: £12.64.£8.85Current price is: £8.85.
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.
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.
