The handbook that comes with some of these drives say they can only be used at 70% of rated current of used occationally. and if you use continuously, then only 40%.. Have you tested running this at 8 amps for a long duration, like days? I heard that they burn out completely.
The primary rectifier of the PSU GBU810 its datasheet says this can do 8A @ 100℃, the 2 primary swithcer 2sc2625 its datasheet says this can do 10A and the Secondary Rectifier Diode N-D92-02 its Datasheet says this is rated at 2 x 10A (20A total). If the specs of these parts is to be believe it will be able to deliver 8A continuous at 220-240 volts input primary voltage even if the parts are derated at 40% but as always it is different with actual test , unfortunately my place is not suitable to test parts like this for extended period and just do not have the funds to run the test for days due to electricity cost.
I can only suggest an oversized psu with with a properly temperature controlled fan that way the fan does not turn on when the load is low to medium.That means asking a seller if there psu has a temperature controlled fan.I had a few psu from Ruiding Tech. the one they use for there RD60XX series power supplies though the minimum voltage the psu can be set is only 53Volts but it is still a little bit high for the TPA3255.
@@boknoynaruto3824 Currently I'm using meanwell lrs-350-48v, the fan is annoying. I don't need a variable power supply, just 48V will do. Fosi sells 48V5A but it costs 3x the price of meanwell which doesn't make sense to me. Any other hidden gems you found?
Thank you for performing this test.
Thank you for dropping by.
Thank you for the power supply information.

Any recommendation for tpa3255 power supply without fan?
My current one has a fan and its noticeable.
