Using a voltage regulator

Background: I live in Mexico. We suffer from a highly fluctuating voltage system. I have put voltage regulators on all sensitive electronic equipment (refrigerator, microwave, washer, dryer, computers, modems, routers, etc.) but use an S 15 APC surge protector on the stereo system.

Question: Since the APC a surge protector but NOT a voltage regulator would it be wise to put a voltage regulator between the wall outlet and the APC? Currently I have to set the high end of the APC to 135 volts to prevent it from constantly sounding the alarm and going to battery back-up.

We also suffer from brownouts which can be just as deadly to equipment.

Is this not what you have? If not, it might be an option to consider. I looked up APC S15 and it's a Power Conditioner with battery backup and it does voltage regulation. I have the APC H15 that doesn't include battery backup.

I'll keep looking for an S15 surge protector.

Gotcha - My APC H15 has voltage regulation but doesn't switch to battery power so it much function differently than the S15. Mine simply turns on a warning light to let me know if it boosting or trimming.

If you don't need the battery backup you could try an H15 or even double down?

Puerto - What specifically are you concerned about for your equipment? The APC S15 is, in a sense, performing a voltage regulation function because it isn't allowing voltages outside of a certain range to reach your equipment. It almost sounds like you're looking for something that will avoid "sounding the alarm" more than you're in need of better protection.

I'm almost thinking that a power regenerator might be what you're looking for, but not sure how they would perform under the power conditions you describe.

I can't imagine how. It might limit current and that can have a negative effect on sound quality, but it won't damage anything.
