Cathodic Protection Rectifiers, Gas Station Series, Air Cooled

Low-cost CP rectifiers limited to 1,500 watts of DC output.

Add to Wish List Add to Compare

The Farwest “ProLine” air cooled cathodic protection rectifier, manufactured by Universal Rectifiers, Inc., is a low-cost rectifier option with the same
 reliability as the Standard air cooled rectifier line. Limited to 1,500 watts of DC output, this smaller rectifier is used for applications such as gas stations, pipelines, storage tanks or other non-hazardous locations where continuous duty, DC power is required.
