If I have a 3A power supply on 24x7, does that mean there's a constant draw of 3A from the electric company? Or does that mean that I can draw up to 3A, but it'll take only as much energy as I need?
I just got that 300lb SmartHome maglock, need to get it 315mA. This is something the wife actually loves, and if it works out in practice, she wants 2 more. RadioShack sells a 3A p/s, I only need 1A, but their price is pretty cheap and I can finish up this project tomorrow.
