content: And who needs 24V 380Watts , and for what?You can use 24V in machines but the powerhungry electronics such as the servos use higher voltages and the rest is happy with less than 100W, a 230V PSU to 24V 100W is about the same price....Perhaps for solarpanel owners ?

content: Quote from: matt09 on May 05, 2022, 12:42:58 pmWhat niche project would that be?Where would I have 71V DC input that needs to be 24V output?I had many odd projects in my life but never anything like this.

content: Well if some manufacturer designed and build them there should (have) be(en) an application for them.But 380W is not your average hobby project.

content: Unfortunately that still is a relatively uncommon voltage range. I guess they might work on a 48V system but how common are those? 110V is much too low to work from rectified 120VAC mains. Vicor makes some nice devices and these do look to be high quality but I'm at a loss as to what they would be useful for. While they are expensive to buy new, they're only worth something to someone who needs that particular niche part.

content: Just to comment on use cases.I don't know about electrical codes in other countries, but in europe it is common that up to 56V there is no legislation or code on how wiring has to be done.Building code does not apply on low voltages, making it very ease to wire up equipment.That's why Wifi Access points etc. are using POE power up to 56V.Also telephone systems use 48V - remember old phones were powered by the telephone exchange.So if you create a 48V power supply, you then can use any wiring, i.e. use coaxial cable to carry power to a (GSM) transmitter - where these units are very likely salvaged from.regards, Bart
