The switched mode types (cheaply available on the bay) work for me. You need to know how many Amps you require before you make your choice. Tweakie.
@Woodie49, if you are looking for one for the stepper then eBay is your friend. I got three from there. Depending on the amps you want they go somewhere between $19 to $30.
The Motor Controller I thinking of useing is the one 3-Axis Unipolar CNC Stepper Motor Driver / Controller 3 Amps per Phase. ebay item number 280911250280 This power supply, 24 volt DC output Meanwell S-150-24 power suplly 6.5 amp, ebay number 131169023214
@Woodie49, put links I'm too lazy to copy and paste the numbers. 6.5A is kind of small. Is a 15A power supply that much more money?
