| April 2012 - Carlo
Gavazzi is proud to announce the launch of our new DSF-PV Surge Arresters. Compact and DIN rail mounted, these devices protect the long-term
investment of photovoltaic (PV) installations and feature Type 2 (Class C) protection from
transient over-voltage due to indirect atmospheric discharge and switching actions.
Approved per UL 1449 3rd Edition, CSA and EN61643-11 (VDE 0675, part 6-11), the DSF is
compliant with future norm EN50539-11 and the new French standard UTE#C 6-740-5, which
specifically prohibits the use of fuses for mandatory backup protection. Our special
internal technology provides for backup protection enabling the DSF Series to be safe in the event of a short circuit, saving cost and space of
fusing. Our new DSF Surge
Arrester is the solution for
combiner box manufacturers and as a replacement for older products.

Significant advances in technology yield a product representing the best-of-the-best in PV
surge suppression. Internal varistors are protected against any leakage current that would
otherwise damage or cause premature aging when the nominal DC voltage is temporarily
exceeded. This condition is likely to occur in the early hours of daylight when the solar
panels are cold. A red optical indicator shows the protection status and voltage-free
contacts offer remote status monitoring. The removable plug-in cartridges ensure fast and
easy maintenance without the removal of any connections.
