In this video we test the WZ10020L Step down converter. First the module is explained, specs are shown, settings are explained. Then we test it with input 110V, 90V, 70V, 50V, 36V, 24V, 19V and 12V and the output is tested with 10A to 20A in all above mentioned voltages and 5V and 3.3V output as well. The input current and output current and power is show to calcualte effeciency. The output ripple voltage is measured using oscilloscope and MTTP is tested and LiFePO4 is tested. Thermal view of the module with maximum of 20A shown to see which spost is the hottest. We provided our conclusion nat the end.
