DEHN EM-1366 DC PV rozvádzač IP66 1000V Type 2 SPD 11 stringov 11 MPPT

The DEHN EM-1366 DC is a high-quality, hermetic IP66 rated DC PV combiner box designed for outdoor photovoltaic systems. It integrates a Type 2 surge protection device (SPD) from Dehn, ensuring reliable overvoltage protection for up to 11 PV strings and 11 MPPT inputs. The robust UV-resistant polycarbonate enclosure and integrated DC disconnector make it ideal for harsh environmental conditions.

Advantages

Integrated Dehn Type 2 SPD with 20 kA nominal discharge current and 40 kA maximum discharge current for superior surge protection. Hermetic IP66 enclosure ensures dust-tight and water-jet protection, suitable for outdoor installation. Supports up to 11 PV string inputs and 11 MPPT outputs, providing flexibility for large solar arrays. Includes string overcurrent protection via integrated fuses and a DC disconnector switch for safe maintenance.
