I builld a 12 V UPS system and I used some relays to provide some remote contol of it.
I try now to build a 48 UPS system based on my 12 V design.
However, I have difficulty finding 48 V relays. Most of the relays that I found are 12 V or 24 V.
I'm suprised that I could not find similar 48 V relays because basically the only difference would be the coil.
I could build a small power converter using a Zener diode and a transistor, but it would be simpler using the correct relay.
I wonder is someone would have any recomendations for various relay sizes, see below the type of relay I used from Amazon.com:
