@Jeremie or @DJ.... I know the ezb4 has a min VIN of 4.5V just was wondering if any of these 2 Mean Well power supplies (links below) would be enough voltage to run an ezb full of servos... 100A or even 60A should be more than enough current, but what about the voltage? Would I be getting brownouts all the time?
5v 60A Power supply
5.5v 100A Power supply
Just to clarify, a brownout happens when the voltage drops due to a demand in current not being able to be met. If the current capacity is beyond maxed out the voltage supply drops. Servos need a power supply that can meet their in-rush current demands. When initialized all at the same time there is a huge current demand from the servos.
So there are two solutions:
1. Get a large power supply as you suggested. 5V 20A should suffice for the revolution robots (we are currently looking into this) but if you have a larger robot such as an inMoov, 5V 60A or 100A may be in order.
2. If the servos are initialized in sequence instead of all together at once the in-rush current demand goes way down.
Thanks again Jeremie

It says they are out of stock but I'm going to wait for one.
I hope that link comes thru OK, If not check out the InMoov forum -Power Supply
