DC PV System Surge Protector

PROSURGE's Type1 CA Surge Protective Devices are designed for PV/ Photovoltaic system dc-side protection against the damaging from surges and spikes caused by lightning and other electrical sources; are fully comply with UL1449 5th edition as Type 1ca SPDs, and Class II/T2 SPDs per IEC/EN 61643-11/31.

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.
