dc surge protection device

PROSURGE PV50 series (48Vdc~1500Vdc) are class I & class II (or T1+T2 ) PV DC SPD designed for DC application such as PV/ solar system dc-side surge protection. Built in high energy MOV, Iimp 7.5 kA 10/350μs, with thermal protection, quick thermal response and secure disconnection.

Type 2 surge arrester designed for low voltage DC system against surges at the boundaries from lightning protection zone 0B-2and higher. In accordance with EN50539, IEC61643-11 and UL1449-4th DC SPD for common mode protection Pluggable module design, easy replacement High discharge current 40kA 8/20 Reliable supervision due to disconnection device; Fault indication by red indication flag in window; With remote alarm terminal optional;

Photovoltaic system Surge Protection PROSURGE® SPV series employ high energy Metal Oxide Varistor (MOV), and constructed with our patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened.

Photovoltaic system Surge Protection PROSURGE® SPV series employ high energy Metal Oxide Varistor (MOV), and constructed with our patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened. They are recommended for used on the dc-side of the DC-AC inverter, and PROSURGE® SP series on the ac-side to protect AC mains power supplies. The number and location of SPV SPDs on the DC side depend on the length of the cables between the PV array and inverter.
