Public Broadcasting-Audio Signal Surge Protection Device



Product Introduction

LEIK audio signal SPD is designed according to IEC and related lightning protection standards. It adopts multiple protective circuits and imports high speed protective devices. Quick response speed, low output residual, superior transmission performance.

This product uses metal casing. It’s well-sealed and it has dustproof and anti-corrosion function. Its interface is pressure interface terminal. It uses series mode to connect. And it is installed between protected device and external line.

 

Features

◆  Over-voltage protection for audio circuit

◆  Discharge current 10kA

◆  Quick response time (10-12s)

◆  Keep in low-voltage state

◆  Two-poles connect lightning leakage circuit.
