Switch-Mode Power Solutions for Cathodic Protection
The Defender series provides a comprehensive set of enhanced control features, along with extensive environmental, electrical surge and lightning protection. These products utilize advanced high frequency switch-mode power conversion with closed loop control to provide significant performance advantages to the cathodic protection industry. Environmentally sealed power supplies make the system an ideal choice for demanding outdoor environments. Closed loop control reduces required field support and maintenance, and extends the life of both structure and anodes.
Full systems are available for both indoor and outdoor cathodic protection applications. The high frequency
switch-mode power electronics are fully sealed and submerged in oil to create a modular and easily replaceable air-cooled power supply. Full systems employ a state-of-the-art Astrodyne TDI controller used to automatically adjust output voltage for changing cathodic protection conditions.
Stand Alone Rectifiers
An environmentally sealed power module (ESPM) provides up to 2500 watts of output power with constant current control from 0 – 50 amps. The high frequency switch-mode power electronics are fully sealed and rated to be watertight, submersible, dust tight, corrosion resistant, sleet resistant and ideal for demanding environments. ESPMs are designed to be modular and can be paralleled with other like units for increased system output of scalable applications. Rectifiers are compatible with an Astrodyne TDI system controller, or one of your own design
Portable CP Testing
CP Toolbox is a rugged and portable test rectifier, weighing less than 25 pounds. The system is lightweight and easily hand carried into the field for testing ICCP installation sites inside a durable compact case. Advanced digital control provides the user with unlimited output interruption configurations. CP Toolbox provides advanced ICCP field testing capabilities through an intuitive user interface. The system is equipped with both manual and interrupt control to accommodate a variety of field testing needs with user defined on and off time for precise output interruption.
