In 1995, SurgeX® introduced a new type of surge protection technology called Series Mode®, which blocked and contained surge energy without the use of any sacrificial or diversionary components and did not contaminate the safety ground. Improving upon the original technology, Advanced Series Mode with zero let-through technology was introduced in 2005. This, along with other proprietary technologies such as our Impedance Tolerant® EMI/RFI filtering, SurgeX ICE®, and COUVS® Catastrophic Over/Under Voltage Shutdown, differentiate SurgeX products from all other power conditioning products. Today, SurgeX is the leading manufacturer of AC power conditioning and surge elimination products. Our leadership position comes from our engineering focus and commitment to provide the best products, customer service, and technical support in the industry – all backed by a dedicated team of professionals.
