DEHN Introduces New Surge Protector with High DC Breaking Capability for 600, 1,000 and 1,200Vdc PV Applications

The PV industry, now generating at dc voltages of 600 and 1,000V, has placed exceptional demands on the currently available SPD products intended to protect systems components from the effects of lightning caused surges and transients.

In response DEHN has introduced a new technology and product, specifically designed for PV systems, to function under the issues associated with these dc voltages. The new DEHNguard M-YPV-SCI addresses those issues by incorporating a switched fused circuit in parallel to the discharge circuit, enhancing protection even in the case of dc grounding faults. This SPD is available in a 3 module device and 2 module device.

DEHN’s unique SPD will be UL-14493rd edition compliant for these new dc voltage applications making your task of obtaining compliance to UL-1741 that much easier.
