Surge Suppressor

The Rayvoss TVSS, with STRIKESORB technology, protects equipment from AC surges. Instead of traditional MOV and SAD technology, the Rayvoss contains one large MOV that is encased in cylindrical aluminum housing. This design prevents MOV disintegration, eliminates the need for fuses, and keeps the unit from catching fire or exploding. The TVSS is maintenance free, with an expected operational life span of more than 20 years.

Power Module

The TRS series of front-end power modules produces up to 2500W of DC power at 24V, 28V, or 48V. Each hot-swappable module features input power factor correction, a Class B EMI input filter, overload and short-circuit protection, and remote sensing. A ball-bearing fan cools each module. You can build or integrate a module into any system using a 19-in., 2U-high companion rack that holds three units.
