Overview
The DT-TELE-SHDSL Surge Protector was designed to meet the special requirements of SHDSL data transmission. It is specifically designed to provide Lightning, RFI, ESD and transient surge protection for maximum data security with minimum signal attenuation.
Surge protection for SHDSL systems
Reliable telecommunications are indispensable in today’s industry. The sensitive systems used in these cases work with high frequencies at low signal levels and are networked over a wide area. Surge voltages here quickly lead to largescale failures and, in the worst-case scenario, data loss. The SHDSL Surge Protector takes the form of an adapter that can be easily installed between incoming telecommunications cables and a modem. The pluggable connection ensures fast and flexible installation and only needs to be grounded by way of the black cable or DIN rail base.
Attachment plug with surge protection for two SHDSL telecommunications interfaces (ports). Connection: RJ45 (RJ12/RJ11) and plug-in screw terminal block (COMBICON). Alternatively, can be snapped onto a DIN rail.

| Protection Against Surge Voltage |
Digital telecommunications systems (DSL) are safely protected against surge voltage by SHDSL Surge Protectors. Due to the high bandwidth of the surge protectors, the transmission signal is not influenced. Use is possible up to DSL 16000. All signal wires and the ground conductor must be connected to the surge protector according to the connection scheme. Any DIN rail should be grounded.
