Wanted a way to use my ebike capacity in case of power outage. Searched a while for 48VDC USB chargers, but there's not a lot available. Since there's already a wealth of equipment for cars. figured I'd go for 24V.
The casing is repurposed 1U Server PSUs.
DC-DC converter is set to 24V.
DC-DC converter heatsink was milled to fit in the height.
The 2 12v PSU fans are wired in series.
