where does one buy a 600VDC 10kW power supply?

Given the application is not distributing the DC then that certainly alleviates a variety of safety concerns. 

And yes if you have no in-house electrical engineering capable of setting up a simplified supply, then a commercial supply that complies with all applicable standards (whether it be for mains connect aspects, or safety to operators, or something related to connectors if you are not using fixed wire to the load equipment) is appropriate. 

I'd suspect that safety related aspects of the total system would need to be competently assessed and documented, as a way to cover identifiable risks, and that mitigating those risks comes back directly to the specs of the power supply just as much as the connection and use of the power within your widget.  Just one example is whether there is active monitoring of the DC rails with respect to an earth fault - the power supply may include that - if not then commercial devices like from Bender can be used for interlocking.

Indeed. I am the only skilled person they have. I have confirmed I am happy to work with 600V given that I have done mains work to my knowledge this is as dangerous as in, "it kills". We do vehicle stuff so assuming no earthing in the vehicle there would be no earthing in the test. Should we temporarily earth any metal body and use a bender to protect from any faults on the DC side like an RCCD would do on the AC side?

The whole thing will need to be risk assessed and measures put in place to keep unauthorized people out either by physical means or signs and instructions on this being a no go area (discipline is lax where I work).

We recently got an ITECH regenerative DC supply https://www.itechate.com/, they do plenty of other supplies to and perhaps a bit cheaper than some of the big names. Website isn't great; but their support was pretty good when we had some initial problems with a faulty internal fan causing the unit to trip.

I've also used Magna Power in the past and they were fine too.

Yes a customer of ours apparently has just had a load of ITECH stuff put in. I have been told by one of the distributors that he can't see how they can be CE marked but the guy selling them said hat there are 2 itechs, the other is RS in house brand or something to that effect.

I am surprised you ask this question!

That means no person in your company has basic training with this kind of power?

There are courses offered now for the car repair business for the correct handling of electric vehicle safety in the repair shop. In Germany, a car repair shop is not allowed to work on electric vehicles, without having done this safety course. They are not even allowed to repair a bumper!

I highly recommend such safety course before starting work on this project!

We do vehicle stuff

Does this mean battery charging ?
I'm not across recent EV power connections as to whether the power supply has all the smarts, or the vehicle has total control of the power flow/protection/charging profile.

I did indeed suggest such a course. But do these courses teach you how to work with high voltages or how to set them up as well? It's like the wiring regulations for buildings, they don't teach you how it works just how to install it.

we do heat transfer

I do not know about this in your country.

In Germany the full course is almost 2 weeks long and you learn everything from the basics to details of handling electric vehicles and its all hands on.
Only when such certificate exist, is the car repair shop allowed to work on electric vehicles.

We are not working on electric vehicles, just designing and building equipment for them. So really it's just about higher voltage safety.

A safety assessment would likely indicate that the test vehicle be solidly earthed for the purposes of testing, assuming that has no implications.  It sounds like you then position some accessory equipment in the test vehicle and provide a cable harness to your equipment.  You then need to map out all the hazards and how to mitigate them. 

I guess some initial summary would include if your equipment and all cabling was completely insulated, or had protective earth connections to all key or exposed metalwork, and to some suitable IP rating, and does it include safety protection for plausible fault situations like over-temp sensing etc.  There are usually guidelines in local standards as to the minimum requirements to manage various hazards - the list could go on and on - and you would need to be competent in identification and assessment.

If you want a 'proper' power supply ask photonic induction.
