Hopefully this is an easy one :-)
I have a 4.5 to 6 servo I'd like to power via EZ. I'd like to reduce the servo's voltage by splicing in a regulator (see below) between the EZ so I can bring the EZ to full load.
Anyone see a problem with this?
Thanks,
Daniel

I'm powering everything via a 30 amp Mean Well power source to resolve the amp issue.
I originally had a regulator going from the power supply to the EZ to reduce load so to not damage the servo. The regulator was set at 6 v (clearly too low hence the message).
My next thought was bring the EZ power supply up enough to eliminated the message but splice a 2nd regulator between the EZ and servo to bring down its power draw.
Here is a link for the regulator:

Now all of this could be moot if my servo could handle what I'll feed the EZ. Its a GWS Heavy Duty S777 6BB Servo. I've been trying to find specs on it but so far I can't. I also plan to run a couple of standard EZ servos via this board as well.

Here will be your problem...
Even though your power supply can offer up 30 amps, the regulator output to the servo will only be 3 amp max. Pretty certain that won't be enough to handle the servo in-rush current as we explained in one of your other posts.

Your idea is correct to step down the voltage from the 12vdc power supply your using. BTW, that 30 amp power supply should be just fine and will be able to power your servo nicly. I would not worry about having to buy a bigger one. Of course I don't know your total load but we'er just talking this single servo right now. You need to use a step down voltage regulator able to supply enough amps to your servo. That is the trick here.
I've found a cool little adjustable Switching voltage regulator that I'm using on my B9 arm. I had it powering 3 servos without a problem and is rated at 10 amps. It's not cheap and a second device is needed to adjust the voltage one time to what you will be needing. Castle Creations makes this sweet little Bec 10A Switching Regulator. Switching means it runs cool and uses little energy. If you place this between your power supply and the servo you should be OK:
Castle Creations CC Bec 10A 6S Switching Regulator
Here's the device your going to have to use to change the voltage:

When you hook this little gem up you will only need to use two of the three wires on the end with the connector on it. This is the voltage output side. Use the Red and brown and cut back and tape the yellow. You'll get what ever voltage you select between these two wires.
Hope this helps.
Thanks,

I purchased the Meanwell 5V 60A power supply but I'm still getting "My battery is Low" message. Any suggestions? Is the output adjustable to a higher voltage via the small control on the left?
Thanks,
