My newest Power Supply Design

This little guy about 12" x 5" x 5" and is an AC/DC Power Supply. It takes in a super weirdo AC input that isn't PFC friendly and outputs combined 250W across 34V/24V/12V/5V rails. It's about 93% efficiency at the moment but I hope to tweak things a bit to get higher. It provides telemetry over CANBus using CANOpen layer.

It's a heavy brick.
