I always start such a search (i.e. amateur electronics construction) at Radio Shack and Amazon. Search under "DC Power Supply"

Don't be afraid to spend too much money on this since if your an experimenter you'll probably want if for something else in the future. Don't be afraid to spend $50 on it.  Sep 28th 2017, 05:02 AM #23 Junior Member Join Date: Sep 2017 Posts: 13 So I've found 2 types of DC power supply. Not sure which one is best or even if their specifications match my needs. Can you advice? https://www.amazon.com/Yescom-Precis...c+power+supply https://www.amazon.com/SUPERNIGHT-Un...c+power+supply Sep 28th 2017, 06:36 AM #24 Member Join Date: Apr 2017 Posts: 86  Originally Posted by yafimski So I've found 2 types of DC power supply.

I buy everything from eBay ... this one is also 5A, 30V for only$12.... " 30V 5A Digital DC Power Supply Variable Adjustable Lab Bench Test Equipment Tool | eBay "

10A , 30V would be better if you want to spend that much ...

It's all about Amps and Volts , and if it looks right ...
