Harmonic Filters
-
ENTES Harmonic Filter Reactors are used in serial connection with capacitor banks in power factor correction units. By using these types of detuned reactors it is possible to increase the capacitor impedance against harmonic currents and to keep the resonance frequency under the frequencies in which main harmonic currents occur by shifting the resonance frequency.

Ground EMI Filters
-
High-frequency signals on ground is never good news - it interferes with normal operation of equipment and creates electrical overstress (EOS). However it is easy to block propagation of EMI on ground by installing highly-effective ground EMI filtes in ground lines. Our unique patent-pending ground EMI filters provide very low impedance for DC and mains' power while effectively blocking propagation of high-frequency currents throughout facility or equipment ground. Ground filters meet safety standards, as well as ANSI/ESD S6.1 and ANSI/ESD S20.20.
