About Power Regulator
You are able to tell the utility of an invention by how often people actually think about it. A power regulator is generally far from most people's minds when using an electronic device, but the odds are that if the device itself doesn't have one that the power it is using has passed through one at least once on its way to you. While you don't have the same needs as a large scale power distributor, a basic voltage regulator still has its place in hobby and other electronics projects where maintaining a relatively precise flow of power is important to the operation. It is important to note that the type you'll be looking for is generally dependent on the kind of power you're dealing with, AC or DC. Examples of both kinds of regulators are available from eBay's reliable sellers. You just want to make sure that you really need that pre-owned regulated AC power supply instead of a DC one to avoid needlessly causing damage to the regulator. Keeping power available at the right level is just as vital as keeping everyone working on a project on the same page, so don't skip out on a power regulator when you think you might need one.
