Editing Commodore 64 Power-Supply Protector (C64 Saver) (section)

=== Why the trip point is as high as 5.4 V ===

Carlsen explains this, and it matters because a reader who sets it lower will get nuisance trips:

: "Feedback from a few users indicated the Saver would trip when they turned their computer off, and it remained in failsafe mode until unplugged from the PS. Apparently some power supplies output can jump up past the failsafe point when the load on them is suddenly removed (computer off). That's why the trip point is set as high as it is. '''5.4 volts is still under the "absolute maximum rating" specification for the RAM chips.'''"<ref name="carlsen" />
