At what current percentage of the rated current should the power supply be adjusted for testing the galvanic isolator?

When testing a galvanic isolator, it is important to consider the performance under higher load conditions to ensure that it can adequately handle surges and maintain its function even under stress. Adjusting the power supply to 135% of its rated current allows for a thorough examination of the galvanic isolator's response to conditions that may exceed normal operating parameters. This testing ensures that the isolator can effectively prevent galvanic corrosion by properly isolating or managing the electrical potential between connected systems, even when subjected to high currents.

Testing at this elevated level also provides a safety margin that accounts for variations in the load or unexpected surges that could occur in real-world applications. By using a percentage above the rated current, you simulate the worst-case scenarios that the isolator may have to deal with, thereby ensuring its reliability and safeguarding the connected systems from potential damage associated with galvanic corrosion.
