Talk:Battery eliminator circuit

How about mentioning upfront that a BEC is really just a voltage regulator, and its historical name likely is due to RC hobbyists building their own circuits and thus having a very "RC" perspective as opposed to an electronics perspective? Voltage regulators are common and widely used, while the term "BEC" isn't really relevant (from what I gather) outside of the RC hobby. I have no sources except various RC forums.

There's an equal historical basis from 1960s transistor radios. For portability, these used batteries (and as they used transistors rather than valves, they could now be carried in one hand, even with their batteries). However their running costs were expensive and so there was a desire to use them from the mains. A "battery eliminator" was then a literal name, as it replaced an existing battery and usually fitted into a case exactly the same size, so that it could be placed in the same compartment. These were sold commercially, also made by hobbyists. Their difference from an RC BEC is the supply: rather than just a DC voltage regulator, these now dropped a high AC mains voltage, rectified it and then (sometimes!) regulated it.

That's battery eliminator, which is completely unrelated. 2620:15C:113:700:791D:8B52:3A5A:65A4 (talk) 19:57, 26 May 2022 (UTC)
