If I set a power supply to provide 12V at some amperage and then turn on the power supply, are those 12V delivered instantly? Or is there some ramp up to 12V with a capacitor system. I'm trying to simulate plugging in a battery using a power supply and not sure if I need some type of switch/resistor system to simulator this.

Most power supplies require a short time to stabilize. To simulate plugging in a battery, first turn on the power supply and allow it to settle, then plug it in.

Hi E,
A switch after the power supply, should do what you want.
