OBO VG-BC900S11 PV systémové riešenie v puzdre, 2x1 PV string na 2 výstupy, Typ 2 SPD, 900 V DC 5088565

Protect your photovoltaic installation with the OBO VG-BC900S11, a pre-wired surge protection solution housed in a UV-stabilized polycarbonate enclosure. Designed for systems up to 900 V DC, it combines two PV string inputs into two protected outputs, ensuring reliable operation for your solar array.

Overview

This PV system solution integrates Type 2 surge protection devices (SPDs) in a compact, wall-mountable enclosure. It is engineered to safeguard inverters and other sensitive equipment from transient overvoltages caused by lightning or switching operations.

What stands out

• High continuous operating voltage of 900 V DC, suitable for long string configurations.
• Nominal discharge current of 20 kA per pole (8/20 µs) and maximum discharge current of 40 kA per pole for robust protection.
• Voltage protection level ≤ 3.5 kV, ensuring effective clamping of surges.
• Thermal monitoring with status indication for easy maintenance.
• IP65-rated enclosure for outdoor installation, resistant to dust and water jets.
