Dolycon distinguishes general industrial drives from its CT112 solar-pump ranges. CT200 is presented as an open-loop vector drive; CT112S has a separate published DC-input and pump-output model table.
CT200 control
Sensorless open-loop vector control
Separate solar family
CT112S has DC VOC, recommended MPPT voltage and rated output-current columns
Important distinction
PV input voltage must not be treated as AC mains input voltage
Questions for this product range
Is the application industrial AC supply or direct PV pumping?
Provide the exact model and its motor-side output current.
For PV pumping, confirm array VOC, MPPT window and pump compatibility.
