Overview

The TPK-7-PVxxx series is a Type 1+2/Class I+II DC surge protective device designed specifically for photovoltaic systems operating from 500 VDC to 1500 VDC. With built-in MOV technology, it safeguards the DC side of PV installations such as solar panels and inverters from lightning-induced overvoltages. Featuring full-mode protection (+/-/PE), compact DIN-rail design, and optional remote signaling, this SPD is ideal for both utility-scale solar farms and residential rooftop setups.
