New Power supply. Need input

[InkStained]

So I've made a prototype power supply unit and I need input from people to move forward with manufacturing...
I've designed this one to do the following...separate adjustment for voltage from 0-24v. And separate adjustment for frequency from 50hz-200hz. This is allowing me to use any machine regardless of spring setup for any application. This will also allow me to run a low tension rear spring on any machine as well to avoid overheating coils.
For example, I can run a color machine at a slow 90hz and adjust the voltage strengh for a harder or softer hit, accordingly without sacrificing the speed... run the same exact machine instantly at 140hz with the exact voltage and DC.. Or run a fast 140hz liner and adjust the hit by changing the voltage, again without changing speed.... then on the fly.. run the same exact machine at 100hz with the same exact voltage and DC to do tight fills.
This is all done by turning a knob on the PS. With each function set individually.
Here's he beat part. You can do all this on one machine, regardless of setup
The way the output is designed, the contact screw will now adjust the stroke only. Another good thing is that I can ensure a perfect 50% duty cycle for every machine that is hooked up. I am also working on making this adjustable with a 15% +/- adjustment.
Whatever you change voltage, HZ, or DC.. none will have an affect on each other.
Everything will still run on standard clipcord or RCA so your setup would not change.
With the exception of needing different needle setups, you'll be able to use your favorite machine for anything.
How useful do you think this can be to the industry?
Whats everyones opinion?

Bump. I'd like to hear input on this one.
