Sparky2 Posted October 9, 2013 Share Posted October 9, 2013 I have a Tripp Lite LCR2400 voltage regulator / power conditioner that I have run all of my gear from for seven years now. It will boost output voltage to a steady 120v if it hits 118.5v or below, and reduce to 120v if the supply exceeds 121.5v. I recently noticed that the input indicator displayed "LOW" and my studio receptacle was giving me 115v +/- (measured w/hand meter). So I measured the output put of the LCR and it was 126.4v! I tested the unit around the house and at other locations. Between 118 and 121 it reads Normal input voltage and does not change the voltage (per spec). If the voltage drops below 118 it will add 11v+. It doesn't stop at 120. At 118 I get 129.4! I had no way of checking what happens above 121. I contacted Tripp Lite technical support/customer service. After a few back/forth emails, they told me it was out of warranty and suggested "I swap it for a new one." I asked if it was worth repairing and they told me that they do not offer repair service on these units. They were also not interested in analyzing the defective unit to determine what went wrong. I asked them "How I can feel secure that a new unit won't provide too much voltage when they don't even care why this one went bad?" and got no response. I mentioned that I have suggested these units many times on forums over the years and that I believe good customer service (and reputation) would include return of the defective unit and at least an offer to purchase a factory reconditioned replacement. And that maybe I should have spent the extra money on the Furman. Their reply was that they don't sell the units, they don't repair them, they don't make the schematics available to the public, and here is a list of vendors that sell them. Sure I got 7 years of service from this and it only cost about $240 US (now $260). It was a good value but I am not sure I should buy another or throw this away. So my questions for those who understand electronics are: Would you think this might be a simple repair? A bad component on a circuit board? Is it possible for something like this to exceed 130v output? Won't that much voltage damage gear? Would you buy another one? (The Furman costs $1,700!!!!) If not, shouldn't it be simple to turn it into a basic noise filtering surge suppressor power strip? I love this thing. It ran our entire band and powered QSC PA! And now I have to wonder whether I should spend the money on a Furman. Some clubs definitely provide us with less than 110v, especially when the refrigerators kick on. And the catering hall dimmers make a lot of noise. Thanks for any helpful suggestions. Mark Quote "Think Pink Floyd are whiny old men? No Problem.
