Re: JEBO WP-40

Few posts back we were discussing that you would need a low pass filter to plug the signal to the pump(to convert the output signal from digital to analog). A low pass filter is build with a resistor and a capacitor. I'm saying that when using a low pass filter the max output that i was able to get ...

Re: JEBO WP-40

Hi Guys,

It's done, just to share something...
Using the LPF it's not necessary, i've used one with 1k resistor and 4.7KuF and the max output was 3.8V, connecting directly from the PWM i got 5V in max power.

Still working on modes, to improve them.
All the best.

Plug + to va and - to -24V in the pump.
Ok, lets do this!

Re: JEBO WP-40

Hi Guys, I don't have an RA but i'm having some trouble with this pump... My controler burned up 4 days after i connected the pump, so its not working. Tried to plug an AC/DC converter to reduce the noise and run the thing at 22V but the converter was probably a bad piece of equipment and it burned ...
