Description

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. Features Simple to Operate AC & DC Surge Protection Lightweight Component Chassis Highly Efficient Power Conversion Fully Solid-state "Switch-Mode" Operation Pure DC Output Constant Current Output Technology Simple Output Adjustment 12-volt DC Power Supply for RMU and Portable Interrupter Maintains Constant DC Current Output Analog & Digital Current Output Readings Built-in Interrupter Interface Test points for cross-checking meter accuracy Pre-wired RMU Terminal Strip Rejects Induced AC Operates on any single-phase power from 115 to 240 VAC without primary tap changes Operates up to 55 degrees C with over-temperature protection Dead-front Panel and Side Shields Two Power Output Choices eliminate the need for exact power output rating Product Advantages High operating efficiency of 80 to 90% Pure DC power output with no AC ripple Lightweight construction Built-in interrupt interface Built-in RMU interface Variable AC input without AC input tap changes Analog and digital output and status display Over-temperature sensors and protection Built-in DC power supply for RMU & portable interrupter Standard "Dead Front" safety panel Constant current output control, 0.1 amp steps 115 VAC convenience outlet with GFI protection Standard AC & DC surge protection Standard RMU terminal strip Standard 3-door aluminum enclosure ETL Certified 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.

No cabinet. *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.
