Does anybody have a link or a suggestion as to what AC Power supply I could use with over 20 large Servos? Also if I wanted to use external battery what size and AMPs.
I'm currently using a 12V AD to DC with 1.25 amp power supply. When running the EZB program ( auto position) running 10 large servo, it works for about 3 times then seems to not move the servos. I unplug the power supply and reconnect it and it works for about 3 servo moves.
Any help would be appreciated.
You need far more amps. The v4 has a 20 amp fuse. I would look at a 12 volt, 20 amp power supply which would let you do what your battery would allow. Batteries allow you to use a lot of amps.
You could use an 480 to 850 watt computer power supply but should do some research on what wires to use and how to jumper the power supply to work.
You can find 12 volt 30 amp regulated switching power supplies on ebay for $20 some even have free shipping.
So you're saying I can directly connect to the EZB V4 board with a 120V AC to 12 DC power supply up to 20 Amps without damaging the EZB. Correct?
If I us just a 12VDC battery with high amps can I connect it directly to the EZB too?
Thank you, d.cochran and robot-doc.
Yes, you can also connect 12 volt batteries directly to the EZB(4). You might consider SLA (Sealed Lead Acid) batteries. They will come in a variety of amperage capacities to suit your needs. Of course you will also need a way to recharge those batteries. And again there are several chargers available with different amperage capacities to accomplissh the task.
Thank You Robot-Doc.
Hum. I just burned up my EZB V4 using a 12VDC 8Ah SLA battery, smoke came out of the board and no more lights. It did work for about 2 minutes.
I think I will get a servo power board to power my servos. But now I just blow 199 or so bucks. stress

The v4 can handle more that 12 volts. Did you connect it backwards? I have connected multiple v4's to 12 volts multiple times without an issue.
