PCB Mounting SPD – Pluggable while install with soldering socket

The PCB mounting surge protective device is easy untegrated in PCB and close to sensitive electronic element inside device, to minimize the potential impact of lightning events. The PCB mounting SPD will help to significantly reduce the cost of substantial repair, replacement, system downtime and the loss of revenue.

Prosurge’s PCB mounting SPD is size optimization and space efficiency, which is a high performance but low cost solution for the industry of power electronics. It employs high energy Metal Oxide Varistor (MOV), and constructed with patented thermal protection and arc extinguishing technology which ensure safe disconnection while faulty current or abnormal voltage happened. Prosurge PCB mounting SPDs have comprehensively improved the safety performance and proven to be excellent fail-safe and self-protected protective devices because of patented technology.
