Surge Suppression


This wide range of surge protection devices is designed for data line, telecommunications and other specialty applications.




AccuGuide - 60 Hz
The AccuGuide® interconnect assembly maximizes performance by transmitting transients generated by lighting and switching with minimal voltage drops. Each AccuGuide unit includes our patented coaxial cables with minimize inductance. All systems also produce extremely low impedance, unattainable in conventional interconnect. As a result, the assembly delivers practically the entire surge to the Surge Protection Devise (SPD), clamping voltage are greatly reduced, and system performance is improved.

Flow Meter Protection - 60 Hz
The Liebert FLW4 and FLW5 Series suppressors are designed for the water and waste water industry. These multistage hybrid suppressors address over voltage transients with gas tube and silicon avalanche technology. In addition, sneak and fault currents are mitigated with new Positive Temperature Coefficient Thermistors (PTC's) which consist of solid state resettable fuses. The units are encapsulated in stainless steel pipe nipples making them suitable for use in severe environments. The FLW4 models protect a signal pair and the FLW5 models protect a signal pair plus the cable shield (drain wire).

The SND Series surge protectors are designed specifically for medium exposure applications. Thus, the protectors can be used on pairs inside a building or leaving the building in conduit up to 500 feet. The SND Series offers several distinct advantages over other current technologies. Among the advantages are low cost, no series resistance, very durable, and completely solid-state.

LTS 1 Series - 60 Hz
The LTS-1 and LTS-2 Series is a multi-stage single or two pair surge suppressor designed for high exposure applications. These products were specifically designed to meet multiple low voltage protection applications in the fire and security industry.



LTS 1 Series - 60 Hz
LRA 5 Pin Module - 60 Hz
The LRA Series is an advanced, solid-state primary telecommunications five pin protection module. The module fits any industry standard five pin building entrance protector housing. All models employ state-of-the-art silicon breakover technology as the active over voltage clamping elements, along with fused over current circuitry which allows normal telephone current to pass, but quickly blocks damaging fault currents. The LRA Series modules must be grounded in an appropriate housing to Building Approved ground for proper operation.



LRA 5 Pin Module - 60 Hz
LBT42 Series - 60 Hz
The LBT42 Series surge suppressor is a dual pair (four wire) module implementing three stage hybrid technology. This module addresses over voltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses "Positive Temperature Coefficient Thermistors" (PTC's). The PTC's increase resistance several orders of magnitude when overcurrents are removed. The ability to self restore in this manner significantly increases suppressor performance and survivability.



LBT42 Series - 60 Hz
Tel-200 Series - 60 Hz
TEL-200 Series modules are fused solid state secondary protectors of Key/PABX C.O. (Central Office) trunk pairs. The units are available in two different circuit configurations. The TEL-200 is constructed with solid state silicon avalanche foldback technology and fuses. The TEL-200T features solid state silicon avalanche foldback technology and Positive Temperature Coefficient Thermistors - PTC's. These protection modules are intended to be used in conjunction with proper primary protectors (UL 497).



Tel-200 Series - 60 Hz
SBG Groundrail - 60 Hz
SBG Ground Rail - Fits Standard 66M1-50 Punch Down Blocks Liebert SBG Ground Rail - Designed to fit standard 66M1-50 Punch Down Blocks. Allows Liebert's TEl, EXT, SND, HSDS Series and other similar Surge Suppressors to access ground when snapped onto the 66M1-50 Punch Down Block.



SBG Groundrail - 60 Hz
LTAC Series - 60 Hz
The LTAC Series suppressor was specifically designed to protect electronic instruments used by the water industry. It combines hybrid AC power protection and signal line protection in a NEMA 4X polycarbonate case. The AC power suppressor can supply up to 600 watts (total) on two separate output connectors and has a 10 amp replaceable fuse to prevent overloading the protective elements. An "INST PWR" LED provides visual indication that power is applied to instruments. Signal line protection is accomplished by the PC642 Series available in a variety of voltage clamps. Signal current can be monitored by reading the voltage across the 10Ohm, 1 % resistors (TP1 & TP2 @ or TP3 & TP4). All leads going to the LTAC board are terminated by quick disconnect or barrier block connectors to facilitate easy removal for service or replacement.



LTAC Series - 60 Hz
LBT64 Series - 60 Hz
The LBT64 Series surge suppressor is a single pair cube implementing three stage hybrid technology. This cube addresses over voltage transients with gas tubes and silicon avalanche components. In addition, sneak and fault currents are mitigated with resettable fuses "Positive Temperature Coefficient Thermistors" (PTC's). The PTC's increase resistance several orders of magnitude when overcurrents exceed safe levels. A normal state resumed when overcurrents are removed. The ability to self restore this manner significantly increases suppressor performance and survivability.



LBT64 Series - 60 Hz
LBT52 Series - 60 Hz
The LBT52 Series is design to protect two pairs of wires specifically for alarm and security systems where operating currents can be as high as 2.5 amps. Electrically, the LBT52 Series is a rugged series hybrid implementing a staged complement of MOV's and copper wound inductors. This design reduces series resistance to 0.2 Ohms per pair. These products are intended to mate with the 12 pin industrial socket SPOS-12. The LBT52 Modules plug into a base assembly (SPOS-12). The base assembly can be mounted to any flat surface, and should be located as close as practical to the protected equipment. Terminal 2 and / or Terminal 5 should be connections to Building Approved ground with 12 gauge solid wire.



LBT52 Series - 60 Hz
LBT-232 Series - 60 Hz
The LBT-232, utilizing silicon avalanche clamp devices, is a state-of-the-art surge protector for IEEE Std. RS-232C peripheral devices. The LBT-232 simply plugs in series with the data cable at or very near the equipment to be protected. If very long cable runs, or outdoor runs are present, the addition hybrid protectors at the building entry of the cable are recommended (see LBT42 Series).
