Yeah I initally done the same equation, 900W x 4 Servos, but as its peak power and not continous it is apparently not needed to have sooo much power supplied. As capacitors and such in the controllers will make up for the lack of power (or so I am told), regadless it seemed in logic to be still way to low having only 4x 350W PSUs suppling the power.
Also I found the breakout board is limited to 48Vdc and 30A so in order to get more power the motors I might have to by pass the BOB. As such I am probably going to meet half way with the 900W x4 and the current level and get a 1.5KW supply at first hooked up through the BOB and then later if I feel it needs more get another 1.5KW and bypass the BOB for two Servos power (connecting the Earths together).
Or even possibly starting with 1KW (less then I currently have, but a lot more managable space and cableing wise) and getting a 2KW to bypass the BOB for three motors later.
Although with above I am unsure on two things (waiting on reply from Hui at DMM-Tech), First) If I by pass the BOB can I use one power supply to supply power to multiple other Controllers/Servos or do I need to give each one a seprate power supply?
Second) can I use different sized power supplies for the BOB passthrough one compared to the others? (I am pretty sure this wont be a problem, but ever one has been talking to me in multiple powersupplies for seprate Controllers.... so I thought I better put it out there)  |
