I finally got this product and had it installed by a licensed electrician. These are made locally and the guy that sold it to me already made and sold 400 of these this year with prices ranging from 300 to 400 US dollars each. Talk about a good, post SHTF business niche when power problems become common! ;- )
I had helped out this guy before and when I called for the favor, he was installing it the following day at exactly 8AM. The electric installation is of course simple, just install it after the breaker, but he also got the L shapes and installed it properly in the wall in a few minutes, checked the W to make sure everything was ok.
So now whenever voltage drops from 220V to 170V all of a sudden, all I hear is a click and the W elevator does its thing automatically. This happens during hot days when people use a lot of power and the grid just cant stand it. With the voltage elevator installed, everything works ok including AC and the power hungry microwave. Ah! The joy of AC! Its bad enough that I pay more for power in Argentina than a house twice its size pays in Texas, but you also pay for something that is of such poor quality its of no use to you. Something similar happens with water, tap water that you pay for but you shouldn’t drink it unfiltered. (well, not if you want to stay healthy anyway... :-) )
This is the device. 9Kva (40 Amps) and gives me 220V with incoming power as low as 155V
I spent a couple hours this morning without power, but at least now when I have power I have it for real and can use all my appliances. Besides, voltage this low will ruin electronics pretty fast. Its also a fire hazard because the electric wiring heats up. I noticed this on the AC cable as I unplugged it before installing the voltage elevator, it felt very hot to touch, but not any more.
Notice that and automatic voltage elevator and an automatic voltage regulator are not the same thing. A voltage regulator may or may not work well with permanent low voltage. Same thing with UPS, some do this but not all of them are designed to work with permanent low voltage, so make sure you’re getting one that is capable of doing so if that’s a long term problem for you. Of course, a big UPS also gives you power if power goes down completely. For recurrent, short period blackouts combined with dirty power issues, it’s the perfect solution, in some cases better than a generator.
Still considering getting a generator though in case power goes down for longer periods of time. Something like this can power an average size house.
