That's what I am trying to get figured out on this actuator. It won't arrive until tomorrow, so I am unsure what it pulls with a load on it.

I did try the old regulator yesterday. Max it would put out with the PTO on was 12.8 volts. Without the PTO was about 12.3 volts. Kinda like a trickle charger!

I talked with one of the electrical guys here at work and was asking him to explain how you can get more then 12 volts dc from 20 volts ac . He explained that when you use a meter to check ac voltage your not reading peak to peak ( Vpeak ) on the sine wave only a part of that  (Vrms), he tried to explain but lost me quick lol anyway he's the conversion for it .

Using this formula  they wanted 20v dc      it would look like this   20vrms = .707 x 28.288  Vpeak  

so I'm guessing that why through the regulator it will give over 12 volts dc but with more ripple and less power  

 

 

Sine wave VRMS = 0.707 × VPEAK, VPEAK = 1.414 × VRMS

Forgot to post the site where I got the calculations

Now that cleared things right up! LOL! As long as it charges the battery, I'll be happy!
