  1. Whatsminer's Power Supply Fix Guide The circuit outlines of Whatsminer's power supplies have been requested previously, however there are not many such records available. I tracked down an article on zeusbtc on the most proficient method to fix what excavator's power supply. So I need to impart it to you here, if have any inquiries, kindly point out to help.

  2. 1. Update the power open firmware • No voltage yield when turned on alone. Interface the control board to the power supply and update the devoted firmware for the control board. Subsequent to restarting the test, the power supply will have a typical voltage yield.

  3. 2. Unusual voltage • Eliminate the power supply screws first, then take out the circuit board and eliminate the fan. Utilize a multimeter to gauge whether the positive and negative shafts of the result terminal are shortcircuited. In the event that there is no short out, measure whether there is a voltage input. The info voltage is for the most part estimated on the two pins of the mass capacitor. • Measure whether the info voltage is around 420V. If by some stroke of good luck estimated around 300V. This shows that there is no strain ascend in the PFC. For security, the capacitor should be released and resulting step estimations were taken.

  4. • To start with, check the control chip circuit for shortcircuits or unfortunate welding. VCC supplies capacity to the control board chip circuit, so check whether the VCC power supply is ordinary. • Measure whether the diode triode of the VCC circuit is standard. On the off chance that it doesn't work, it ought to be supplanted. Nonetheless, after the power-on estimation, the VCC voltage continues to beat, and the VCC circuit doesn't work. Thusly, since VCC is redressed by numerous diodes and results various arrangements of voltages, if it's not too much trouble, release the Capacitor subsequent to controlling off. In this way, it is important to quantify whether every rectifier diode is working.

  5. • After the estimation, in the event that the channel capacitor is shortcircuited, it truly intends that there is an issue with the rectifier yield. The estimation semiconductor works. The diodes are on the front side and covered with stick. Need to pry the paste substitution, and supplant it with new diodes. Measure after substitution to affirm that there is no short out. • At long last, complete the power-on test to affirm that the result is typical and the shortcoming is disposed of.

  6. 3. The fan is running regularly, yet the result voltage is unusual • Utilize the dark test lead of the multimeter to ground, and the red test lead to gauge a similar pin places of the four driver chips and look at. Typically, the worth of a similar pin of the chip is something similar. In the event that the pin position and the ground esteem are very unique, the IC driver circuit might be shortcircuited. Assuming there is no indication of consuming on the outer layer of the chip, it is possible that the MOS tube it drives is shortcircuited. Eliminate the intensity sink of the MOS tube.

  7. • Utilize the diode stuff of the multimeter to quantify the fourth pin (control pin) of the MOS tube. Find the shorted MOS tube. The fourth pin of the typical cylinder is around 0.57V. Switch the multimeter to the obstruction stuff, and measure the strange gathering of the fourth pin of the MOS tube. In the event that there is more than one harm, it should be supplanted.

  8. 4. Voltage yield decrease • On the off chance that the fan isn't working, make sure that the fan link is connected appropriately. Or on the other hand see whether the fan speed is excessively quick. The fan is turning excessively quick because of the great temperature. The power supply is locked to safeguard itself, so there is no result.

  9. • Check the fan drive circuit to check whether the temperature- detecting wires on the four intensity sinks are free. The shortcoming of the digger is a fan issue or a temperature issue. Actually look at the significant line. In the event that everything is good to go with the temperature control on the heatsink, there might be an issue with the chip program. You might have to reset the firmware.
