Eng: works well at 100 w and 75 degrees, efficiency about 90% in X2-X3 mode and 12-20 input, and down to 80% at X4-X6 and less then 12. Simple but good tl494 based boost dc/dc, clear meander. Of course it is not 400 w, minus 1 point. ----------------- rus: normal clear step on tl494, very clean square, pulls 100 watts at 75 degrees. Efficiency 90 multiplied by 2-3 and 12-20 volts input, drops to 80 at 4-6 times and below 12 volts. Reliably starts from 7.5 volts. Minus the score for you about 400 w, he even with a radiator this will not pull. Transit and diode do not indicate, everything is fake. I think you can pull out a watt of 200 with a radiator, but at the input volt 12 and output for example 24.

Good quality product as described. I installed it on a Lab Bench Power Supply for voltage selector, and works perfectly.
