However for larger and more expensive units like the APC Smart Online RT series, it actually pays to repair them.
Unlike many other UPSes, the RT line actually is very modular. There are about 12 parts that can be removed and repaired easily. These include simple things like controller ribbons to more advanced work such as the power handling unit.
Recently we have been seeing alot of RT units with the Red Overload X and this 2+3 sequence error. They call it an Internal Fault. If you call most refurbishers or APC directly, they will tell that it CANT BE REPAIRED.
Well we can... and have been doing of awhile.
So before you junk your RT unit, consider calling us and getting it repaired
