The voltage drop of a common diode is between 0.2V and 0.7V. Can you how much is by 10A? 10A*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, of ordinary diode, Used for anti-backflow of solar panels, battery charging and anti-reverse irrigation. Effectively reduce heat generation and efficiency. Module parameters: Module name: 15A perfect anti-backfill diode Working voltage: DC5-60V Working 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 degrees Application range: 1. Solar panel anti-reverse irrigation. 2. Various battery charging anti-reverse irrigation. 3. DC-DC constant voltage constant current module output anti-reverse irrigation. 4. More applications are free to play. Colour: green Material: plastic Package Contents: 1 x Anti-reverse Irrigation Module Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
