DCPro Switch-Mode Cathodic Protection Power Supply by Farwest Corrosion

Highly Efficient, Pure DC Output Power with Precise Control

The DCPro Cathodic Protection Power Supply is a durable, switch-mode power supply that provides clean, efficient DC power. With the look of a conventional rectifier, the DCPro requires no computer interface and no confusing menus to navigate. Engage the main breaker and turn the single control knob to adjust the current output.

A bright color display, readable in direct sun, presents both analog and digital output voltage and current output levels with a message window that can provide additional operational messages.

With the DCPro, no longer are very specific output ratings required to overcome output adjustment limitations.

Warranty

 An industry leading three-year warranty provided from the date of purchase.

The following provides the ordering details for the two output sizes available; 30 volt - 20 amp and 50 volt - 50 amp.

With the precise control standard with the DCPro, there is no need to order the exact DC output level you would order with a standard rectifier.  For instance, if you needed a 40-30 rectifier, you can now order a 50-50 DCPro and achieve the exact power output you need.  In addition, the DCPro can be shipped from stock to avoid weeks of waiting for a rectifier.

*The DCPro power supply in the 50-volt, 50-amp output configuration can easily be field configured to provide controlled current to two separate structures.

The DCPro was designed and built as a "two sizes fits most" approach, which may provide a solution for approximately 80% of cathodic protection demand.  If a customer requires more output current, the DCPro may not be the solution.  However, it is also important to remember that DCPro units can be linked together to double the output DC voltage.  Therefore, two 30 volt, 20 amp power supplies can be made to achieve 60 volts and 20 amps if required.
