Power supply KL-150-24 24V/6.3A

If I have 3 steppers (1.76 v dc, 2A, 1.8*/step) and the hobby cnc Pro board, will this power supply work?

Hi PCcruncher!

The KL-150 will work fine. But for best performance, I would recommend either the KL-300-36 or the KL-320-36.

Thanks Crevice Reamer!

What are the advantages of the higher voltage?

those 2 you suggested have a better amp rating, the KL-300-36 is out of stock, so that would only leave me with the KL-320-36 36V/8.8 or 9.6A

Well you can always NOT use the extra amps. The PSU will only supply what the motors draw.

The advantage is in efficiency--More top speed, less lost steps. It's all explained in here somewhere:

Thanks for that link, I'll bookmark it

"Well you can always NOT use the extra amps. The PSU will only supply what the motors draw."

True, I wouldn't want the motors to be wanting more than the PSU can give.

Ordered the KL-320-36
