I have a keling 36V 9.7amp switching power supply. From what I understand, you should always leave a little bit of headroom while using a switching power supply. In other words, I guess I am not suppose to use all 9.7 amps.

I would love to set up my switching power supply to run two motors...One at 2.84 amps using a KL4042D digital driver, and 1 at 6.4 amps using a KL9082.

With a bit of complex math, I calculated that would I be drawing up to 9.24 amps on my 9.7 amp switching power supply. Is .46 amps enough headroom, or is it necessary to dial down my drivers just a little bit?

Thanks
