This surge protector meets all AC and DC certifications of IEC and UL, and can simultaneously meet the protection requirements of both the DC side (photovoltaic cells or batteries) and the AC side.
Product model: PV20K-670
SPD type: Class II
Maximum continuous operating voltage: 510VAC/670VDC
1、 Product Description:
This surge protector is mainly used for built-in protection of string type photovoltaic inverters or converters. The product meets all AC and DC certifications of IEC and UL, and can simultaneously meet the protection requirements of both DC side (photovoltaic cells or batteries) and AC side. According to different input voltages, different voltage level modules can be selected to form Y-shaped, O-shaped, U-shaped and other protection circuit modes. T1 or T1+T2 and T2 protectors can be selected according to equipment protection requirements. Some inverters are equipped with PID circuits, so gap protection devices (such as discharge tubes) cannot be used between the neutral point (line) on the AC side and the ground.
