80V 5A regulated power supply

[VK3YNV]

Using some of the surplus military bits and pieces, and a Ruidang 80V 5A DC DC converter. The raw 64V AC is available on the purple banana jacks, the unregulated 90V DC is available on the yellow/black banana jacks, and the regulated DC output is on the red/black banana jacks.

The controller allows for constant voltage, current limited, constant current and constant power options. Although constant voltage with current limiting is all I would normally use. Lots of other power supply modules available https://rdtech.aliexpress.com/store/923042

The module I used is this one..

Second one finished. It's possible I could series them up for 160V 5A regulated, since the outputs are floating with respect to mains ground, but I don't have an application that would require 160V

That's a pretty neat job!
Those power supply modules are very handy.
