Zivopower Type 2 DC Surge Protective Device is designed for photovoltaic systems to protect DC-side equipment such as solar panels and inverters from lightning surge damage. Available in 600VDC, 1000VDC, and 1500VDC versions, it features a pluggable design, 40kA maximum discharge capacity, and reliable protection for PV string boxes and inverter applications.
Zivopower Type 2 DC Surge Protective Device is developed for photovoltaic power supply systems to protect DC-side equipment against lightning surge currents and transient overvoltage. It is suitable for use in PV installations where reliable surge protection is required for terminal devices such as solar panels, string boxes, and inverters.
This product series is available in 600VDC, 1000VDC, and 1500VDC versions, with a maximum discharge current of 40kA. It adopts a pluggable modular design for convenient installation and maintenance, and is designed for parallel installation on the DC networks to be protected.
This DC SPD is suitable for photovoltaic solar applications and is typically installed on the DC side of the system to protect equipment such as solar panels and inverters. It is recommended for use at both ends of the DC power supply line, especially where cable routing is external or the line length is long.
