DPVN-Range: The Next Generation in PV surge protection

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

The SPDs of the new DPVN range are the first to be designed with CTC-Technology. CTC-Technology make DPVN protectors slimmer, faster and safer than their predecessors from the DS50-product series and comparable devices on the market.

With patented CTC-Technology, DPVN-SPDs implement the normative requirements of IEC 61643-31 and UL1449 5th edition better than it was previously possible. IEC 61643-31 focuses on the specifications of surge protection devices for photovoltaic applications where as UL1449 applies to safety standards for SPDs.

The DPVN range is specifically designed to protect photovoltaic installations from transient grid surges and the damaging effects of lightning strikes. With an Imax rating of 40kA (8/20µs) and an nominal (In) current rating of 20kA (8/20µs), these devices are suitable for all PV applications, i.e. rooftop systems of any size, single family homes to industrial sized solar farms.

DPVN SPD are available in versions to protect 600Vdc, 1200Vdc and 1500Vdc PV systems. The series will feature two standard protection technologies, MOV and VG-Technology. VG Technology is CITEL's patented hybrid MOV-GSG/sparkgap design. For more information on VG Technology and CTC Technology please visit www.citel.us.
