Experimental Physics and
Industrial Control System

Hi James,
We've done an asyn/stream ioc for the Sorensen DLM 60/10
plus a couple of their DCS models.   The protocols are the
same for these so they should also work for the 60/20.
Let me know if you'd like the protocol and db files.

Regards,
- Bruce

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).
