All seven of its California stations will close immediately.
I thought auto ranging power supplies were typically for voltage but not frequency.
Every one I’ve seen gives ranges like 100-240v ac, at 50-60 Hz.
Then electrical grids are large complex systems defined in analog days and subject to variances for weather, usage, distances, etc, so they also need to support that variability
Even larger appliances like refrigerators, ovens/ranges, etc? Some of these might be 10+ years old.
