Power lines often carry high-frequency noise (EMI), This noise causes multiple problems for equipment operation and sometimes leads to component damage. OnFILTER’ hand-held EMI Adapter provides easy way to observe noise on power lines with your oscilloscope, spectrum analyzer or any other instrument without exposing them to high voltage from the power lines
OnFILTER DC EMI filters greatly reduce noise from switched power supplies, stepper motors and other sources common in today’s equipment and provide noise-free DC power for your sensitive equipment. OnFILTER’ proprietary design accomplishes maximum noise suppression of signals polluting your DC power lines, removing harmful interference typical for industrial equipment.
Operation of servo and variable frequency motors causes a number of problems in a tool, including damage to the motor’s bearings from leakage currents. Another problem caused by this noise is errors in operation of electronic equipment, including test and metrology. Sensitive electronic components processed on such tools as IC handlers, wire bonders, SMT pick-and-place machines and many others can be subject to electrical overstress (EOS) caused by noise from servo motors, affecting yield and reliability.
OnFILTER servo motor EMI filters perform two important functions: they substantially reduce high-frequency noise within the tool resulting from operation of servo and variable frequency motors and improve reliability of motors by reducing leakage current through their bearings. Unique patent-pending technology allows for reduction of current in ground beyond capabilities of regular filters.
OnFILTER offers filters for motor drive and also patent-pending combo filters that include both drive and AC power line filters in one enclosure. This solution prevents servo controller from polluting the equipment with EMI not only from its drive circuit but also via AC mains.
