does anyone know if there is an OEM voltage controlled PSU module

I am looking for 0-20V/.5A output controlled by external voltage
0-10V.
The PSU would be a part of a larger outdoor experimental system, so
an OEM
module would be ideal. I'd rather buy an off-the-shelf module than
waste
my time on designing it.
Thanks in advance...

How about a power opamp? Set the gain to 2.
One possibility (First thing on a parametic search of NSC parts):
LM675T
$2.75
TO 220
4000 mA current output
5.5 MHz gain bandwidth product
60 V maximum power supply voltage
Assuming you use a 24 V supply, maximum power dissipation (0V, 0.5A
out) would be 12W. You will need a heatsink. If you need to go all
the way to 0V a negative supply may be necessary. It should be
extremely simple. I don't know of any modules to do this, but it
should be quite simple.
