AP74 Power Draw

[cfiidon]

I searched the manual and could not find the power requirements for the AP74.  I know the servos are about two amps max, the D180 about 3 amps, the HS34 draws a quarter amp, how bout the AP74 itself?

Secondly, any problem with putting the D180, HS34, AND AP74 on one breaker/fuse (functionally or operationally)?  My harness wire sizes support up to 7.5 amps (20 AWG wire).

Thanks in advance,
Don

The AP74 draws in the tens of millamps. So by itself, a 1A fuse with appropriate sized wiring is fine.

Remember that fuses protect wires, not devices. So as long as all of the wires going through the single fuse can handle the fused current, you're OK.

I understand.  My wiring harness uses 20AWG for the D180, and AP74.  The HS34 harness uses 22AWG.  If I connect all three to a single breaker, I must size the breaker at no more than 5A for the 22AWG wire.

As for the load, it looks like 3A for the D180, 1/4 A for the HS34, and maybe 1/10 A for the AP74.  It looks like a total load of 3.35 Amps and a 5A breaker should handle that load.  Concur?

Thanks

Indeed.
