Carlo Gavazzi DSF-PV surge arresters - April 2012
July 12, 2012 - Carlo Gavazzi has launched the DSF-PV surge arresters, claiming to represent the best-of-the-best in photovoltaic (PV) surge suppression. According to Carlo Gavazzi, internal varistors are protected against any leakage current that would otherwise damage or cause premature aging when the nominal DC voltage is temporarily exceeded. A red optical indicator also shows the protection status and voltage-free contacts for remote status monitoring. The surge arresters are approved UL1449 3rd Edition, CSA and carry the CE and RoHS marks.
