High current three-phase EMI filter for high power applications

EMIS announces the availability of the TMF3333 High Current Three-Phase EMI Filter for high-power applications. The device effectively blocks unwanted electrical noise, which can affect the performance of sensitive equipment and lead to component degrading in power systems.

The EMI filter is designed to handle the maximum current expected in a system without overheating or causing excessive voltage drop. It is designed for low thermal resistance and uses materials that can effectively deal with high temperatures to reduce unwanted heating effects. Frequently used in power supply systems and heavy machinery employing larger components and multiple stages to effectively filter noise while ensuring they can deal with large currents. The filter offers sufficient attenuation across the frequency range, including common-mode and differential-mode noise.

A TMF3333HV version is available for high-voltage applications. Typical applications include three-phase servo drives, three-phase power supplies, wind turbines, energy conversion devices such as inverters and frequency converters, elevators, factory automation equipment, industrial equipment, and building automation.

The TMF3333 EMI filter is chassis mounting with busbar connecting terminals, has a current rating of 150 to 2500A and an operating voltage of 520/760VAC over the frequency range of 50/60Hz. A protective cover is available if required.
