Would a half-decent UPS not solve the problem? More expensive, for sure, but fine for brown-outs and short cuts. I know these were discussed recently, but we used to use them to keep computer systems going in broadcast radio studios where the Buildings department used to cut the power as part of a fire test routine. The transmitter was fed from a computer-based sustaining service overnight, but would not restart at the right place if the power was cut, then restored, without intervention. I got fed up with call-outs on a weekly basis. Pleadings and explanations fell on deaf ears, of course; but the UPS prevented the need for a manual reset on power-up, and I got my beauty sleep (badly needed, according to some...).
