A post on AC Voltage Regulators - Why you might want one

Interesting timing. I have been monitor the voltage in my home for about a month now. I started with it placed in a kitchen outlet and it was very stable at 121 volts. One day when I was making toast the voltage dropped about 2 volts. I since moved the voltmeter to outlets shared by my audio equipment. I have seen the voltage as low as 119 and as high as 125 volts!

I've been using the PS Audio Power Conditioner which cuts off power if the voltage drops to low.

 

 

Yep, @rlj there are a number of units which will cut power off if too low or too high for prolonged periods of time, including any Furman unit with SMP, but they are not voltage regulators.  To qualify it needs to alter the incoming voltage, instead of just cutting it off if too high or low.

This is not a feature everyone needs, per se.  Gear is designed to work reasonably well with a range of incoming power, but if your home power isn't that reliable or you want something that makes sure your gear is fed consistently good voltages a regulator is for you.

Agree: Get a Furman regulator, Almost all high-end recording studios use them. Much better performance than the high priced "audiophile" products. This is the one I use: https://www.bhphotovideo.com/c/product/657351-REG/Furman_P_2400_AR_P_2400_AR_Voltage_Regulator_Power.html/overview
