Sorenson, Lambda and numerous others are making power supplies with LAN and RS-232 interfaces that use SCPI-style command languages. These are all readily interfaced to EPICS using StreamDevice + Asyn. There are other parameters that you might find important to consider, such as how to incorporate interlocks, power supply stability, speed of the power supply, speed of the control system interface, ability to supply controllable currents at setpoints very near zero (a show-stopper for several candidate supplies that we tested).

Hey again,

I forgot to say: If the Sorensen 60-20E can be remotely controlled by
RS232 you do not need to write a device support.
You can simply use StreamDevice + asyn. It's pretty easy to use. I'm
using it for every device controlled via RS232 or RS485 in our lab.

Best regards,
Florian

Hello,

Does anyone have a any recommendations for an EPICS supported DC power
supply to power a ceramic heater which requires current greater than
7A and voltage greater than 25V? We are currently looking at a
Sorensen 60-20E (which can supply 0-60V at 0-20A) which can be
remotely controlled by RS232 or an analog input for ~£1,700.

Before I start writing support for this device, are there any other
power supplies, with support already written, which would do the job
for a similar cost?

Thanks,

James
