Found that in there :)

Yes, this is designed for the telecoms market... as I said, a quality supply....

note also elsewhere in doc... "Designed for free convection" No fans needed!

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,

Regards

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

So Kip's only got 5 years warranty left.

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....

Thanks Irving and Kip.:clap:

Could you clarify (so I can put on my best haggling hat

) - excluding delivery...what did he charge per PSU?

**HankMcSpank** · 25-07-2009

Thanks (& sorry for labouring the point!

)

For anyone wanting to order a few of these - the seller will allow collection via your own courier.....& Parcel2Go will deliver upto 25kg to your door for about £7.50 in total (the ad says they weigh 2.5KG each, so factoring in some 'headroom', you could therefore get 9 PSUs into the one Parcel2Go delivery - can't imagine you'll be popular with the driver though!)
