What is the maximum allowable amperes DC when testing the galvanic isolator with superimposed current?

The maximum allowable amperes DC when testing the galvanic isolator with superimposed current is 0.005 A. This low current limit is crucial for ensuring that the performance of the galvanic isolator is not compromised during testing. In this context, a galvanic isolator is designed to prevent galvanic corrosion by blocking the flow of DC current, which could create corrosive environments for the metals connected to the boat's electrical system.

When testing the device, it is essential to maintain this limit to avoid any potential damage to the isolator or affecting its operational integrity. Higher testing currents could inadvertently lead to the failure of the isolator or produce false readings, misrepresenting its actual performance in a real-world scenario.

Choosing an appropriately low testing current like 0.005 A helps ensure both accurate testing outcomes and the longevity of the galvanic isolator, allowing for safe operation when in service.
