Product introduction

LEIK series communication signal surge protection devices are designed by following IEC and ITU-T relative standard，which adopt multi-level protection circuit and choose import high speed protective device with fast response speed, low output residual voltage and excellent transmission performance to avoid slow reaction speed from traditional lightning protection apparatus and security unit. It is the best and updating surge protection device and is suitable for circuit surge protection of PSTN/DDN/ISDN，especially in  expensive communication equipment protection

The surge protection devices also adopt metal housing with good leakproofness and corrosion protection, which use standard RJ11 crystal and series system connection, are installed between protective device and exterior line
