The new STFE Elite Series of Active Tracking® filters from SolaHD mount directly on standard DIN rails. They have been crafted to provide superior protection from the full spectrum of voltage transients and surges that may impair operation of control panels, factory automation systems, PLCs, and other industrial and machine tool equipment. These filters combine a hybrid clamping network with Active Tracking technology so that the AC input power line is tracked continuously. Response is instantaneous upon detection of extraneous high frequency noise and high voltage transients. Key product features include a patented metal mount clip, UL-listed surge current capacity of 45,000 A, a fully enclosed metal housing, transient protection in all modes, and an LED status indicator.
