ALCO Rectifier Air Cooled UT & SW Series
ALCO Rectifier UT & SW Series Advantages
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 rectifiers feature 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.
