Lower Voltage Servo And My Battery Is Low Message

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,

My $49 5v 60a Meanwell will solve all your power problems... Being 5V means no regulators for anything.... Or a sub c 6v/7.2v NiMh battery pack or a Lipo 7.4V battery, or use more than one of those DC/DC regulators in parallel.... In my opinion those are your 4 cheapest options....

I think I'll give Richard's suggestion of two regulators paralleled a try.

I agree your amp starving your servo. What ever devices, power supplies or regulators you use need to be able to handle the amps you will suck through them. I can't find the specs on the servo your using but I'm sure that regular cant provide enough amps.

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:

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.;)

@Mulberry I think @Dave just solved you problem... The Castle Creation 10A bec looks like it will do the trick....

The parallel didn't work so I'll consider the other options. I've added two springs to reduce the weight load substantially. Too bad a standard EZ servo isn't quite enough though :-)

Thanks,

Hi Richard

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,

Daniel
