Hello! I have 5 avalon psu3300-01 and in all of them, the chassi led blink 2 times green light and then red solid, and the led in control board is green.
The 12v from the Miner control cable harness is ok
I have shorted beetween AGND and SETUP and during the turn on using the switch of the power supply, it delivers 13.5v but that goes out when red light appears.
Can someone help?
Already replaced with new fans and no solution.
okay take 1 of them. put it a case with no hash boards.
just the controller and the fans.
see if the psu works. if it works your issue may be shorts in hash boards.
so go to the working model add 1 hash board and see what happens.
I assume you know you have to feed 208-245 volts to the psu.
get back to us after you do the controller only test.
