This will be my first DIY project involving electricity so I want to make sure I buy the correct components. I'm purchasing a used telescoping column (aluminum and steel, 4000n) that has two actuators hidden within, with two cords coming out the black and red wires within each cord.
Each requires a 24V 3.5A power supply, so I assume I would need a 24V 7+ amp power supply... but then when I Google around, all I get are these crazy looking power supplies with 10-15 different connectors on one side. When I look at the 12V power supplies it's simple... they look like battery chargers, cut off the end and strip the wires, make sure it's the right amperage before I do that obviously, and bam you're done.
Can someone help me figure out what a good beginner-friendly store or brand would be? I am not asking for shopping brand advice, but for safety advice. I don't want to buy something that's going to blow up in my face or electrocute me.
I would prefer something super simple, or a link to a great guide about power supplies (all I could find was some really old information).
