What is the range of frequencies varied during the vibration test for the galvanic isolator?

The range of frequencies used during the vibration test for a galvanic isolator is determined based on industry standards that ensure the device can withstand the conditions it may encounter in a marine environment, where vibrations can vary widely due to engine operation, wave action, and other factors. The frequency range of 10 to 60 Hz is commonly employed because it effectively covers the most relevant spectrum of operational vibrations without extending into ranges that are less likely to occur during standard use.

Testing within this frequency range helps verify the structural integrity and performance of the galvanic isolator under realistic conditions. Frequencies below 10 Hz generally involve low-frequency vibrations that are less common in marine applications, while those above 60 Hz can result in less significant effects on the hardware being tested, thus not providing a full representation of operational stresses.

This specific range ensures comprehensive evaluation, aligning with best practices for marine electrical devices where reliability is critical for safety and performance.
