Why limited lifetime warranty power supplies chosen for cathodic protection systems
Cathodic protection techniques are used to reduce metal corrosion by making the structure the cathode and a more easily corrodible, sacrificial metal to act as the anode. For large installations like pipelines or offshore platforms, DC power supplies provide that current. The larger the structure, the more power is required.
The HWS series was picked for a large cathodic protection system that required a 1,500W rated power supply with an output voltage of 15V. The limiting lifetime warranty of the conservatively rated HWS1500-15 was a decisive factor for selection. The customer recognised that the cost of replacing a failed power supply far outweighed using a cheaper alternative.
