Good board, but at 224W load voltage drops from 35 to 32V. Output voltage floats when mains input voltage changes. There are 35v in output at 220v input. In my case there are 36v output instead of 35V. I need to decrease it to 34V.
Device was in working condition 3 days. It died after overcurrent protection test. Reason is unknown. Seller is not responding. May be that IRF740s are fake and are not able to carry 10A, May be driver is not good for this board, may be driver does not have current limiting at all (current ensing rezistor is present om the board, but circuit is not built-in to use it). I have ali proposal to get 5.46 EUR and keep the board or return device for 8+EUR anfd may bet get 27.3 EUR in some future ( i did tried that once before and could not get money back for 6 months).
The first one broke for no reason after a year :/
The first power supply broke for no reason after about a year in my plate-amplifier with 300W IRS2092 Module. This power supply is not repairable because the controller is molded in plastic. I recommended another power supply.
