They break down proteins to generate energy, and do not produce much heat. They also produce some very smelly byproducts that can make a compost pile stink like rotten eggs or sour milk.

The power conditioner provides protection against surges in power just as a surge protector does, but a power conditioner also maintains a continuous voltage fed to the computer during temporary voltage reductions, such as a brownout.
VFDs and PLCs. 1  As Thomas Ulrich notes, the transformer power rating is the measurement of how much power the transformer can handle without overheating causing damage. Large substation transformers often have three ratings: one for unforced air cooling, one for one stage of forced air cooling, and a third for two-stage forced air cooling.
