These answered my questions perfectly, thank you! I appreciate the warning with about the logic power being separate. We do have a separate 24VDC supply for the logic power on hand and this is for just the Bus Power. Thank you for pointing me to Ixx66 as this fits perfectly with what we're doing here. I have also bookmarked Ixx69 for use if we start using a motor of that type. Thank you for all the help!

Thank you for your help! I found a power supply that I would like to use: http://www.alliedelec.com/images/products/datasheets/bm/Mean_Well/70069759.pdf Ideally, I would use the 48 volt version to power the Bus (we have a 24V DC supply for the Logic). This would allow us to use higher voltage devices in the future if necessary. The current project has the controller running 24V motors on 5 of the axis now. Unfortunately, I cannot find anywhere in the manual where it states that the controller is capable of converting this 48V input to a 24V output. Does anyone have experiences that show this is possible (or let me know if I just missed it in the manual)? As before, thank you for the help!

I'm using a Geo Brick LV 8-axis controller (GBD8-C0-442-10T00000) to drive 5 DC Brush Motors (rating on motor is 30W 24V 2.1A 2000rpm). Since the controller is capable of far more power output than these 5 motors will draw (capabilities listed are 50A peak, 25A continuous, 60VDC Nominal, 80VDC Max), I would like to design a power supply that would allow me to do higher power functions in the future if needed. My questions: 1. Are there any suggestions as to a preferred power supply? 2. I assume the controller is capable of modifying a higher volt supply (say 45V 60V) before sending it to the lower volt motor (here 24V). Is this correct? 3. This project has a limited budget. Would it be advised to purchase a smaller supply that is designed for parallel connection (sized to work for this project) and then purchase additional power supplies to hook up in parallel when future projects arise?
