RSR Variable DC Power Supply

hey so i just want to do a quick video uh introducing people to a couple power supplies that i have showing you how useful they can be and uh basically helping walk people through the difference between constant current and constant voltage okay so in front of me i have the long way uh variable bench power supply it goes up to 30 volts and up to 10 amps as you can see there and i'll have a link an affiliate link in the description below and this is the kung bur uh this is also a dc power supply same thing 30 volts up to 10 amps but they actually make models in multiple colors for this in black and white and they do all the way up to 120 volts with 3 amps or 60 volts with 5 amps so a little bit more flexibility there with what you can get from there otherwise they're really super similar they both turn on and off they both have a ground and negative and positive inputs the main advantage
