Description: High performance-price ratio Simple and easy to operate Small appearance Parameter: Working voltage: 9-80V Working current: 50A (It is recommended to strengthen heat dissipation when using more than 25A) Working internal resistance: 2 milliohms 100V/300A high current 2 milliohm low internal resistance MOS Special note: The voltage drop is 0.04V. If you want to measure the input and output voltage drop values, please connect to the 9V-80V power supply and measure again. The management IC will not work when there is no power input! Note: must be grounded Type: B-without terminal Circuit board size: 44x18mm Material: PCB colour: silver+black Package Contents: 1 x 80V 50A High Current Perfect Diode Module Solar Controller Only 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.
