keep getting a short when I connect a peltier module to DC power source Answered

I am trying to power a peltier module (3.9V 9A 21.3W). I have connected it to a DC power source at 3v and I keep getting a short. I have tried different voltages below the 3.9V and am still getting the same result. Am I approaching this at too basic a level?

How do you define a short?
You need a beefy power source for such a beast if your's is below the 10A mark then it might just cut out.
If you require control a PWM module with a power transistor or SSR will do the trick but it still requires a rated power supply.
