I'm working on an art piece based around an Arduino Mega that essentially requires power for three types of devices:
- Solenoids (4): 24 V, ~100 mA a piece (400 mA, 9.6 W total)
- NeoPixel LEDs (1280): 5 V, ~60 mA a piece (77 A, 384 W total)
- Base stepper motor (1): 5 V, not really an issue because it can be powered with an H-bridge driver from the output of the Arduino
Since the LEDs are the primary current consumer here, we're thinking we'll use this 600 W, 5 V DC power supply (SE-600-5): http://www.meanwellusa.com/webapp/product/search.aspx?prod=SE-600
This power supply has three pairs of output terminals, and is rated for enough current to power the LEDs.
The concern here is how to step up that voltage from 5 V to 24 V to power the solenoids (with enough current). We are considering voltage regulators, boost converters, as well as a high voltage amplifier like the PB64 from Apex Technology (shown in Figure 4 here: https://www.digikey.com/en/articles/techzone/2018/apr/how-to-combine-high-and-low-voltages-in-a-single-design)
Does anyone have any experience with issues like this? How would you recommend managing two voltage levels?
Thanks so much!
