The adustable high voltage power supply proviedes single or dual rail (depending on the type you order) power. It can widely used for many applications like huge nixie clocks, decatron spinners or any other tube circuites ... Ony when using it for analog or even audio applications a little bit more filtering of the output voltage is required since especially at higher power you have quite some switching noise. But for 99% of the applications it works perfect. Nevertheless the output power seems a little bit optimistic. I ran the module at apx. 30W input power (didn't measure the output current) and it got quite hot. But still very good output power for the value.
