Cathodic Protection Rectifiers, Gas Station Series, Air Cooled
For over 30 years, Farwest has represented Universal Rectifiers as a stocking distributor and technical trainer.
Low-cost CP rectifiers limited to 1,500 watts of DC output.
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.
