Air Cooled UT & SW Series
Cathodic Protection Rectifiers

Pole mountable, air cooled cathodic protection rectifiers with swing out and removeable case for superior accessibility for routine maintenance & inspection.

Type "UT" Series

Type "SW" Series

The UT & SW Series air cooled cathodic protection rectifiers, are an alternative to Standard Line series air cooled cathodic protection rectifiers. The UT is the smallest model of the two series with a maximum of 400 watts, with all the same features as the larger SW series. Both Series rectifier features swing out and removable design case, which permits superior accessibility for routine maintenance and inspection. Limited to 1,600 watts of DC output, the simplified rectifier design reduces manufacturing costs and provides an economical rectifier suited for most cathodic protection applications.
