The voltage drop of a common diode is between 0.2V and 0.7V. how much is consumed by 10A? 10A x 0.2V=2W, 2W acts on the diode to generate heat enough to make the diode scrap.New force, perfect anti-backfill diode, 8 milliohm internal resistance, two parallel, ultra low voltage drop, instead of ordinary diode,Used for anti-backflow of solar panels, battery charging and anti-reverse irrigation. Effectively reduce heat generation and improve efficiency.Module parameters:Module name: 15A perfect anti-backfill diodeWorking voltage: DC5-60VWorking current: 15A (MAX) 18A (without heat sink 10A working for a long time, can be used in parallel to increase the working current)Static working current: 0.2mA (12V, there will be errors when the working voltage is different)Working temperature: -40~+85 degreesApplication range:1. Solar panel anti-reverse irrigation.2. Various battery charging anti-reverse irrigation.3. DC-DC voltage current module output anti-reverse irrigation.4. More applications are free to play.Colour: greenMaterial: plasticPackage Contents:4 x Anti-reverse Irrigation ModuleOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
