DEHN Expands Product Range of Surge Protectors for DC Photovoltaic Applications

According to DEHN, the rapidly growing PV industry, now generating at dc voltages of 600 and 1,000V, has placed exceptional demands on the current SPD technology, and previously available SPD products intended to protect systems components such as inverters, arrays, or combiner box components from the effects of lightning caused surges and transients.

Responding to this demand for application at these dc voltages, DEHN has developed and introduced a new technology and product, specifically designed to function under the issues associated with these dc voltages. The new DEHNguard M YPV and PV-SCI addresses those issues by incorporating a switched fused circuit in parallel to the MOV discharge circuit, permitting the disconnect to operate arc free.

DEHN has recently expanded their initial product offering to now include a broader range of voltages and product configuration. These unique SPD products are now available for 150, 600, 1,000 and 1,200V (and soon will have a 1500Vdc SPD) applications and are configured in both a "Y" (3 pole) configuration for floating systems, and a 2 pole design for grounded systems.

DEHN’s unique SPD are UL 1449 3rd edition compliant for the applicable rated dc voltage applications.
