The simplified version of the legendary Brick Wall Series Mode Protectors, the PWOM20 is a module unit. Created to be designed into original equipment, this unit has proven valuable in various applications from highway signs to data acquisition systems. By allowing an OEM to design a Brick Wall unit into their product, both the manufacturer and their customers are insured of the best in surge protection.
