Advance-Galatrek has launched a new range of transient voltage surge suppressors (TVSSs), with devices optimised for a variety of applications.

Advance-Galatrek has launched a new range of transient voltage surge suppressors (TVSSs), with devices optimised for a variety of applications Each model in the new StrikeSafe range offers the technological breakthrough of a novel matrix design, providing the ultimate lightning and transient zone protection for both single and three-phase mains supplies

In accordance with the criteria defined in BS EN6651: Appendix C 1992, models within the range are designed expressly for protection of sensitive devices located at the main distribution panel area (Zone C), the sub-distribution panels (Zone B) and individual office equipment and applications such as PCs, fileservers and phone systems (Zone A).

Because an average of 20% of transients are generated outside a building, from sources including lightning strikes, electrical grid switching, system faults and other industrial installations, many models in the StrikeSafe range deploy a unique combination of silicon avalanche diodes (SADs) and metal oxide varistors (MOVs).

The primary level of protection is provided by SADs in an innovative matrix design - a configuration that offers superior performance when dealing with the sharp rising edge of a transient infected voltage waveform.

StrikeSafe's SAD matrix reacts almost instantaneously to harmful transients, as well as providing a lower clamping voltage than traditional MOV only devices.

Secondary protection is provided by a separate MOV matrix, which activates as the transient energy increases to a level greater than that which the SADs can handle.

The combination of SAD and MOV matrices means that StrikeSafe provides a lower total cost of ownership, when compared to MOV only devices, as the SADs do not degrade with use.

Because the SADs provide the initial response to the transient energy, this helps to reduce wear and tear on the MOV components.

The exclusive StrikeSafe matrix design also offers superior reliability when compared to conventional technology.

Individual components are arranged within separate fused groups, offering greater levels of redundancy for critical and awkward to service applications.

As a result, the StrikeSafe range is particularly suitable for protection of wireless installations, at sites such as city centre rooftops, roadside locations and rural environments.

Furthermore, StrikeSafe is the ideal range of TVSS devices to augment the limited front end surge protection capabilities already incorporated within many UPS and DC Power Supply modules.

As these are generally MOV based, they tend not to be adequate for environments that could be subject to regular or large transients.

Using StrikeSafe products in such installations can save thousands in costly UPS and DC standby PSU damage and downtime.

The StrikeSafe range includes wall mounted, DIN-rail mount and hot-swappable plug in modules.

Zone A, B and C devices can be specified for a variety of nominal mains voltages, with a wide range of peak pulse currents.

Depending on the individual application, clamping voltages between 214 and 1300V can be specified.
