I emailed the manafacturer (Minebea) to see if they had a schematic, here's their reply...

thank you for your request.

Sorry to tell you that NMB Minebea gave up that business years ago. No more drawings, spare parts or schematics available anymore,

Yeah, good try, but I thought that was wishful thinking. These were built around 10y ago I think.

Well I managed to get the power supply wired up and it does what it says on the tin... no noise, no fuss, just 500w of power....

The variable output is, well, variable... and it doesn't get switched off...it sits at 42v when the 'inhibit' line below 5v or above 11v, although the SysOut line does switch off when out of regulation.

Also needs no load resistor.... works happily with no significant load.

Will continue to investigate....
