Ohmite's chassis-mount, metal-case power line filters offer an excellent connection to earth. Electromagnetic interference (EMI) filters are general-purpose filters designed to suppress undesirable electrical disturbances in power lines. These chassis-mount filters provide the space available for multiple circuits and provide superior protection. Ohmite offers multiple filter series designed for circuits with a current rating up to 150 A. EMI filters limit the amplitude of interfering voltages on AC power lines and prevent them from propagating into or out of the filtered equipment.
