Main Application

Leiditech thyristor surge protector devices are designed to help protect sensitive

telecommunication equipment from the hazards caused by lighning ,power contact,and power

induction. These devices enable equipment to comply with various regulatory requirements including

GR 1089,ITU K.20,K.21and K.45,IEC 60950,UL 60950,and TIA-968-A(formerly known as FCC

Part 68).

Typical application including:

●

Central office switching equipment. Analog and digital linecards(xDSL,T1/E1,ISDN……)

●

Customer Premises Equipment(CPE)such as phones, fax machines,modems,POS terminals,

PBX systems and caller ID adjunct boxes.

●

Primary protection modules including Main Distribution Frames(MDF),building

entrance equipment and station protection modules.
