Yes thank you again jairbj for helping me find the solution! To answer your question about noise: I typically use 230-240vac. However because of your question, I conducted a special test to check the noise of my PSU at 120vac (25 amp DC load) and 240vac (25 amp DC load). I did not notice any...

:bigthumb: Thank you jairbj!! Problem now solved!! 8) 8) I took off the rear adapter and connected AC voltage lines directly, and guess what...the power supply did NOT turn on, which is exactly the same situation as you reported. Logically, I started thinking the adapter must have some...

Yes, that is the adapter I am using on R4850G2. Shorting the START PINS to ground, or shorting the 2 PINS to each other, or leaving both PINS OPEN do not create any change to the power supply startup sequence. The power supply starts when AC Voltage is applied, however I would rather have the...

Problem with startup- with no solution yet: I have R4850G2 that automatically starts operating WITHOUT having to connect START PINS to GROUND. After reading previous posts, I conclude this is not normal because START PINS must be grounded, otherwise the unit will not power on. I want to be...
