The Edco ACP-340LED is an upgrade to the popular Edco ACP-340, adding a failure indicator as well as remote sensing circuitry. In addition, this unit offers much better lightning protection than the standard Edco ACP-340.
The Edco ACP-340/540LED filtering surge protectors absorb power line noise and switching transients that other suppressors and RFI filters pass through. They can replace the RFI filter when high attenuation of noise above 25 MHz is not required.
The Edco ACP-340/540LED utilize Thermally-protected Metal Oxide Varistors (TMOVs) with an integrated thermally activated element designed to open in the event of overheating due to the abnormal over-voltage, limited current conditions.
