LF60X (60 Amp Line Filter)

For more details call:


The LF60X will protect equipment from malfunctions due to conducted interference coming into the equipment from line, especially line to ground (common mode) noise and transients.

HESCO/RLS line filters are designed to provide the required noise suppression to allow most equipment to meet FCC specifications for conducted emissions.

HESCO/RLS line filters are a cost effective solution for equipment that is environmentally subjected to the damaging effects of transient noise and other interference that may result in unnecessary memory loss or down time of a traffic controller. Troubled intersections may need no more than a reliable LF60X line filter to correct this potentially dangerous situation.

The excellent characteristics of the HESCO/RLS LF60X will provide the attenuation of RF interference you need to achieve a safe operational environment for your equipment.
