From the project
Oltronix D400-007D power supply error amplifier PCB
This repository contains a redesigned regulator board for the Oltronix D400-007D 400 V DC power supply.
The goal of this redesign is improved safety margins, better component availability, and improved PCB high-voltage layout compared to the original design.
