I have an LED circuit built that requires 12V @ 6A (72W) to run at approx 80% max rating of the LEDs. The circuitry works but all the power supply/adapters that I have been able to find with those specifications "pulse". The voltage is constant but the amps vary from 0-6A which makes the LEDs pulse.
I am looking for information on how to look for a power supply/adapter that has constant power output (both voltage and amps). I am in the US and plan to use the AC wall plugs at 120V 60Hz (15A breaker/wiring)
