The GuardDog® WRG-Series is the premier line of Maxivolt products. Primary and secondary protection circuits give clients a redundant layer of protection in the event the first level of protection is expended. SenseTech® form C dry contacts are provided standard on both layers of protection. An optional audible alarm can be added to either the primary or secondary protection circuit. Every device is hand made in the USA and goes through a rigorous and demanding testing process. GuardDog® WRG-Series products feature hybrid circuits consisting of only the highest quality components engineered to provide a clamping threshold for the specific voltage application they are designed for. Safety fusing and the non-ground dependent design eliminate safety risks associated with competitive devices. The various benefits of WRG-Series products provide clients with a quantifiable payback.​
