I paid £19 del for 2, so £22.49 a PSU... cant be bad...

It may take me a couple of days to work out the answer to the volts. Its a TI UCC2985 phase-shifting PWM controller driving 4 x F740 500V 20A HexFETs in a full-bridge, running at 340vDC supply, driving the output transformer, the output being rectified by two BYT16P dual fast 20A rectifiers. Feedback from output to PWM is via a pair of opto-isolators. As such it is not far different to the reference circuit for the 2985 PWM but so far not been able to identify the actual voltage regulation mechanism.

There are a pair of FA3624 PWM controllers on a daughter board each driving an FP460L hexfet as a single ended flyback converter to provide logic voltages of 5v and 12v (I'm guessing based on the other chips around there, but it would seem logical).

There is another daughter board with SMT parts on that is made in UK (rest is made in Germany) which suggests this was bought in. Havent been able to fathom its purpose yet.
