Summary: A fixed voltage will help lengthen the life of your power supplies and appliances.
Pros: Great product to regulate voltage if necessary. Most electric companies are suppose to keep the voltage into home consistent, but if yours varies this product will keep it regulated. Mine was varying by over 20V, before I started using this voltage regulator.
Cons: There is a voltage range switch on the back. Make sure this switch is set correctly for your voltage needs.
Pros: Get an oscilloscope not just a DVM to see if if the wave form is really what is should be.I di and I confirmed it. Voltage was stable also. Made an improvement to my tube guitar amps and hi-fi amp which all need clean power.
Cons: Non really. It was cheap and I've used it regularly with big power hungry tube guitar, bass and hi fi amps. Reduces line noise for sure.
Summary: Had a series of brownouts after a couple power failures and after one these it died. I have occasional brownouts and brought this to protect my HDTV. But at about 4 months, after an unusually high number within a short time it stopped passing current completely and using the reset didn't correct the...
Summary: I have an earlier model, I believe, of this unit, and in getting info on it I found various confusions between the models 600 and 1200. The same manual was used to cover both, for instance. The key components are a circuit board and a BIG HUNKIN' special type of transformer/inductor.
Pros: The unit does what I needed it for, when brownouts happen, the regulator kicks in. You can set the voltage from the back slide button, which was not readily obvious. Great at providing piece of mind.
Summary: plugged this into the wall and plugged an apc surgearrest into this voltage regulator and plug my 47 LED TV and tv stuff into the surge protector. i do not believe that surge protection is enough to protect expensive home electronics. we need voltage regulation too especially for LED's.
Pros: works well too.
Cons: i can't prove it's really smoothing out the electricity because i have not heard it yet.. but i use apc's in datacenter and my apc that protects my home pc's works so i trust this one works well too.
