New range for Photovoltaic installations: DVPN

he DPVN-Series: The Next Level in surge protection

With the DPVN-series of surge protective devices (SPD), CITEL introduces the new generation of protection devices for photovoltaic installations. This series is the first to be equipped with the game-changing CTC-Technology and succeeds the previous DS50 series.

The SPDs of the new DPVN series are the first to feature the new CTC-Technology. This makes the DPVN protectors slimmer, faster and safer than their predecessors from the DS50-product series and comparable devices on the market.

With the patented CTC-Technology, the DPVN-SPDs implement the normative requirements of IEC 61643-31 better than it was previously possible (this applies equally to the American UL1449). IEC 61643-31 focuses on the specifications of surge protection devices for photovoltaic applications.

The DPVN family is specifically designed to protect photovoltaic installations from transient grid surges and the negative effects of lightning strikes. With a discharge capacity of Iimp = 6.25 kA per pole and Itotal = 12.5 kA for the T1+2 combination arresters and In = 20 kA and Imax = 40 kA for the type 2 SPDs, these devices even exceed the minimum requirements of the IEC 61643-32 application standard.
