What is the frequency of the power system used by the Sentinel?

The correct frequency of the power system used by the Sentinel is 400 Hz. This frequency is typical for aviation and military systems as it allows for the use of smaller and lighter transformers and electrical components. The higher frequency reduces the size of the power supply components, which is crucial in applications where weight and volume are important considerations, such as in airborne and portable equipment.

Using 400 Hz as the standard for power systems in various military platforms also ensures compatibility and standardized integration across systems, enhancing operational efficiency. Other frequencies listed, such as 50 Hz and 60 Hz, are generally used in residential and commercial power systems but do not meet the specific needs of the specialized equipment like the Sentinel.
