The Dyna System 30 is a series wired surge suppressor engineered to provide the best protection for mission-critical equipment. The DS 30 units are state-of-the-art hybrid modular suppressors that combine fast-acting silicon avalanche diodes, MOVs and an LC filters made up of inductors and capacitors. These series connected units provide the highest level of protection through efficient low pass filters. Lead length is also a critical factor in suppression performance, multiple wiring configurations are available through LEA.
