Solid State Decoupler

Dairyland Electrical Industries SSD • Solid-State Decoupler

With the SSD line of products, DEI offers decouplers with lower cost and very compact designs. Using proven, solid-state construction, but with new production and packaging techniques, the innovation of the SSD line adds value by lowering the cost of applying protection products to industry. With ratings for AC fault current and lightning, and the ability to pass steady-state AC current, the device outperforms other technologies such as metal oxide varistors, gapped arrestors, and polarization cells. A major application of the SSD is in acting as a “Ground Mat Decoupler,” by separating grounding mats from pipelines (to improve cathodic protection) while still providing over-voltage protection for workers.
