DEHN’s unique SPD is UL 1449 3rd edition is approved for use on DC PV applications for 600 VDC and 1,000 VDC. It’s also available for 150, 1,200, and 1,500 VDC systems. The SPD protects components within PV systems— such as inverters, combiner boxes, and panels—from the effects of lightning-related surges. DEHN has developed and introduced the DEHNguard (Y)PV SCI series for single- and two-pole applications. Both incorporate a switched, fused circuit in parallel to the MOV discharge circuit to permit the internal disconnect to operate arc-free. With over 100 years of experience in this field, DEHN continues to serve the electrical industry in the research, design, and manufacture of surge protection products, offering technical expertise to minimize the effects of lightning-caused transients.
