ZPU5-T2-40PV Type 2 DC SPD for Solar PV System
ZPU5-T2-40PV Type 2 DC surge protective device for photovoltaic systems, with Imax 40kA, In 20kA, pluggable design, and system voltage options of 600VDC, 1000VDC, and 1500VDC.
Product Overview
Zivopower ZPU5-T2-40PV Type 2 DC SPD is specially designed for photovoltaic power supply systems that require reliable protection against lightning surge and transient overvoltage on the DC side. This product is a pluggable multi-pole Type 2 / Class II PV surge protective device, intended to protect terminal devices in a solar PV system, such as solar panels, combiner boxes, and inverters.
The ZPU5-T2-40PV must be installed in parallel on the DC networks to be protected and provides both common-mode and different-mode protection. For more effective system protection, it is recommended to install the device at both ends of the DC power supply line, including the solar panel side and the inverter/converter side, especially when the cable routing is external and long.
With maximum continuous operating voltage options up to 1500VDC, nominal discharge current of 20kA, maximum discharge current of 40kA, and fast response time of ≤25ns, this PV SPD is suitable for modern solar installations that require dependable DC surge protection performance and easy maintenance with a pluggable design.
