33 Amp 12 Volt Power Supplies

These are 12 volt, 33 amp switching power supplies suitable for a range of high current uses. We used them for a public art installation that we were hired to engineer and install and they performed admirably for 3 months. We powered more than 200 feet of WS2812 LED strips with a couple of these power supplies.

The power supply is very clean, here’s a scope trace taken with a load (of LEDs) of about 18 amps.
