Looking for Programmable Power Supply

I'm looking for a 240W (approx) DC power supply 0-30VDC output that I can control the voltage of via analog signals (0-10 or 4-20) or over Ethernet. This doesn't have to lab grade accuracy and control.

Just looking for basic functionality. There seems to be a bunch of high end programmables but having trouble finding basic stuff.

Any help appreciated.
Thanks

I think I found what I'm looking for:

Anyone use these before?
