Dc Surge Protectors 
 

for telecom, cable and data,
to protect the dc lines coming in

Dc surge protectors for telecommunications protocols, cable lines, data circuits, low voltage secondary transient protection/surge suppression, internal, external, weatherproof, T1, DDS, UL 497A, category 4 wiring, Cat 5/6.
 


These dc surge protectors from M-Ti are for your signal, data, cable and telecommunications lines. M-Ti already has over 3,000 configurations available. What follows here are the most common ones. Dc data/signal/modem lines are typically the weakest link in most company's power protection realities. 

Signal lines can allow potentially catastrophic surges to enter into mission-critical systems. If you don't see what you need for protection on these pages, please call us, as we can most likely help you  from the larger solutions library, or even help design a custom product for you.

SLT Series with swivel

SLT (Signal Line Treater) Series:  The SLT Series is a multi-stage hybrid surge protector specifically designed for low voltage and low to medium frequency applications up to and including category 4 wiring.  Models are available for all EIA protocols, 4 - 20mA current loop and standard signal applications from 5V dc to 200V dc. Connector interface choices are modular jack, DB9, 15 and 25 and 3 position terminal block.
TLT (Telephone Line Treater) Series: The TLT Series provides secondary transient voltage surge suppression for (per UL 497A) Telco line protocols. Units provide protection against transients that exceed the nominal operating voltage of Dial-Up, DDS, Dedicated/Leased and T1 lines.

Telco Slider Module

TLT-SEEX (Telephone Line Treater) Series: The TLT SEEX Series provides secondary transient voltage surge suppression for (per UL 497A) Telco line protocols. These telephony surge protectors provide protection against transients that exceed the nominal operating voltage of Dial-Up, DDS, Dedicated/Leased and T1 lines. The TLT SEEX surge suppressor is designed for external mounting just after the incoming telephone junction box, in a weather-proof enclosure. The SEEX includes user selectable switches to bypass the protection circuit if destroyed. In most cases of a major surge, the protector will have given up its life while leaving the phone circuit operable... and it is then desirous to be able to put the phone circuit back into service and call out to have another surge protection board ordered and get back on line.
CLT-SEEX (Satellite - Cable - CATV) Series: (pdf coming soon):
The CLT SEEX Series provides secondary transient voltage surge suppression for satellite, cable and CATV line protocols. These coaxial DC surge suppressors provide protection against transients that exceed the nominal operating voltage of standard CATV lines. The CLT SEEX is designed for external mounting just after the incoming CATV junction box, in a weather-proof enclosure. 

4 Plug DLT data line treater

DLT (Data Line Treater) Series:  The DLT Series provides transient voltage surge suppression for all EIA communication and signal line protocols with data speeds up to 155MHz. These data line surge suppressors provide protection against any transient voltages that exceed the nominal operating voltage and are UL 497B Listed. Each line is individually protected against surge current impulses. (Left is a 4 jack / port unit, bottom left - a 2 jack / port, and below is a CAT 5 rack-mountable 12 jack / port module).
Category 5 surge strip

M-Ti is also a custom dc coax-data-telecom-line filter/SPD/surge protector manufacturer.
