Product Overview
The KRF series are EMI filters manufactured by TCI. The filters are designed to work with a broad range of frequencies, between 150 kHz to 30 Mhz. At the core of the KRF series filter is a network of capacitors and inductors.
When the KRF series filter is fitted to a power line, the conductor channels through noise frequencies by acting as a short circuit, while the inductor, which is in series, blocks high-frequency noises from passing through.
Industrial engineers will find the KRF series useful, particularly in protecting equipment from harmful EMI emission generated by non-linear loads. With devices like variable frequency drives operating in increasingly high frequencies, there is a growing need for EMI filters.
KRF series filter helps to protect the line and load from excessive electrical interference, and prolong the lifespan of sensitive equipment. The filters are built to fit into a compact enclosure and boast a lightweight design. The neatly arranged terminal blocks ensure installations can be performed with ease.
Whether it’s protecting against differential or common-mode noise, installers will benefit from the cost-effective design of KRF series filters. The filters are engineered to ensure compliance with the EMC directives and are cULus-listed and ENEC marked.
The KRF series EMI filters have proven to be effective solutions in preventing drive cross-talk and interference in various applications. They have been installed for motor drivers, elevators, wind farms, UPS and other common industrial devices.
