[CA] [CA11] Type 2 Rotary Drive Current/Amps

[skibum]

The only specs I can find on the current draw for the rotary drives show that the Type 2 uses between 60 and 84 watts.

A quick calculation shows that at 12 volts, the drive unit will draw 5-7 Amps.

But, and this is where my confusion comes in, the chart shows that you need the ACU-400 for the Type 2 rotary drive.

Why?

Specifically, why the ACU-400 instead of the ACU-200?

The ACU-200 specs say that it can power a drive unit up to 15 Amps continuous, which, if the specs on the Type 2 Rotary Drive are to be believed, is more than double the amount of current that the drive unit will draw.

The ACU-400, with a 30 Amps continuous rating seems like absolute overkill for a drive unit that supposedly only draws a maximum of 7 amps.

Can someone tell me what I'm missing here?
