Used in remote places, such as supermarkets and amusement arcades, money changing machines are usually ‘always on’ and therefore need to operate both efficiently and reliably. The power supply that the manufacturer chose for it machines was the LS35 from TDK-Lambda. These convection-cooled, general purpose units are well-suited to budget conscious applications but are up to 4% more efficient than similar products available on the market. They come with a host of standard features, including overcurrent and overvoltage protection and a power on signal. What’s more, the extremely efficient design of the LS series achieves excellent thermal properties and thereby offers high reliability.
