Fort Pierce, Fla.-based DEHN has expanded its range of surge protectors for DC photovoltaic applications. The company says these new products are designed to function under certain conditions present at DC voltages of 600 V to 1,000 V.
The new DEHNguard M YPV and PV-SCI incorporate a switched fused circuit in parallel to the MOV discharge circuit, permitting the disconnect to operate arc-free. DEHN has expanded the initial product offering to now include a broader range of voltages and product configurations.
These products are now available for 150 V, 600 V, 1,000 V and 1,200 V, with 1,500 V models available soon. They can be configured in both a Y (three-pole) configuration for floating systems and a two-pole design for grounded systems. The products are certified to UL 1449 3rd edition for the applicable rated DC voltage applications, DEHN adds.
