Main Application
JKS’s
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.
Access network equipment such as remote terminals,line
repeaters,multiplexers,cross-connects,WAN equipment,Network Interface
Devices(NID).
Data lines and security systems.
CATV line amplifiers and power inserters.
Sprinkler systems.

◆
All measurements are made at an ambient temperature of 25℃.Ipp
applies to -40℃ through +85
℃ temperature range.
◆
Special voltage(VBO and VDRM) and holding current(IH) requirements are available up on
request.
◆
Off-state capacitance (C
O
) is measured at 1 MHz with a 2 V bias and is typical value.
