OVP2 Overview
The Over-Voltage Protector (OVP) design has been established since 1999 as the premier explosion-proof (Division 1) protection device for use on cathodically protected structures, using solid-state technology. Dairyland offers a variation of the OVP design in a molded housing, designated as the OVP2, for Division 2, Zone 2, or ordinary locations. The OVP2 package offers the same conservative design and features of the OVP, but in a lighter weight and lower cost package.
