Thyristor Surge Protector WEOS4-100/120AS WEOS4-100/120AS Document: W0101061 W0101061 Version: B Features Bi-directional crowbar transient voltage protection High surge capability High off-state impedance, Low leakage current Low on-state voltage Short-circuit failure mode Main Application WAYON's thyristor surge protector devices are designed to help protect sensitive telecommunication equipment from the hazards caused by lightning, power contact, and power induction. These devices enable equipment to comply with various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968-A 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. Electrical Parameters (Tamb=25) VDRM WEOS4-100/120AS WEOS4-100/120AS VBO IBO VT IT CO IH IPP Max. Max. Max. Max. Max. Max. Typ.
