Cathodic Protection Station with Switching Power Supply for Buried Metal Structures

[gigel]

Benefits of the Switchmode Cathodic Protection Rectifier:

• Can be installed in any existing CP (Cathodic Protection) cabinet.
• Optional integrated remote monitoring (data transmission).
• Increased output efficiency, over 90% compared to conventional transformers.
• Improved efficiency means less heat and greater thermodynamic stability, especially in hot environments.
• Smaller and lighter in size than the conventional transformer rectifier counterpart, resulting in lower transportation and maintenance costs.
• High-quality DC output significantly enhances cathodic protection performance.
• Reduced carbon footprint.
• Lower AC current consumption.
• Less copper usage to reduce costs, weight, and theft.
