Solid aluminum build, tested at 20A and works fine, it heats quite a bit. The voltage only dropped from 12.12V to 12.02V at this current. Note that the fan is NOISY, and you might want to change it if you're doing videowork and homemade lighting. It has an internal 2pin 12V connector. On the outside, the supply has 3 (-) and 3 (+) 12V connectors, along with a Neutral, Phase, and Ground connections. Be careful though, they are on the right side and you could easily get shocked. You can also fine tune the output voltage with a potentiometer. No flicker on the lights, but be careful that it sends back some noise to your power socket (I noticed interferences with other devices when plugged on the same wall).

Packaging was too bad=some of chassi was bent. They are adjustable from som 10.6 to 13.7 V and deliver some 48 A with max 48mV ripple. Voltage drop at 40A is only 300mV. The blower seems to run on high speed at all times. Will restart in some 15 sec after overcurrent switchoff automatically even with a 40 A load connected... Real powerhouse, and high efficiency i e hardly warm, but somewhat noisy.
