Lightning Surge Protectors

Transient voltage is responsible for billions of dollars of equipment damage and downtime annually. Mitigating damaging surges reduces stress on electrical equipment, electronics and electrical system wiring.

To properly protect electronics and electrical systems today require TVSS that mitigate Multiple Surge Types.

Commercial TVSS Should Defend Against Two
Distinct Types of Surge Damage. Many Don't. Ours Do.

Quality, performance and effectiveness of transient voltage surge suppressors differ by manufacturers. At times, these differences can by quite pronounced.

In commercial and industrial environments, there are multiple surge types present. TVSS that effectively protect against both Impulse and RingWave type transients in all modes, provide the highest level of protection.

Many TVSS focus on Impulse type surge protection. Electronics are easily damaged by these surge events. However, in commercial settings, lower-level RingWaves are found to be much more prevalent and equally as dangerous over time. Equipment is increasingly at risk from these repetitive RingWave surges.

TVSS designs focusing on impluse surges, even with EMI/RFI filtration, are not effective in preventing damage from RingWaves. Critical electronics need Full Spectrum ProtectionTM Designs.

Medium Voltage Surge Protectors TVSS

Does the TVSS effectively protect against all transient types? Some TVSS do. Some TVSS don't.

Our TVSS perform in all-modes against both Impulse and RingWave Transients...

Commercial Surge Protectors

Industry Leading Product Warranty...

A product warranty should include both manufacturing defects and unit failure while defending equipment against surge activity. Many manufacturers only warranty product defects. 10-Mode, Data Line, Surge BarrierTM and Advantage™ Series Warranty covers defects and SPD failure for 25 Years.
