First of all, thank you very much for the answer to my last question, but I still have some problems during the use of the CRD-22DD12N and would like to be helped.
According to the operating manual, ‘In charging mode, the output voltage is calculated by the digital controller when the input voltage is between 650V and 900V, and the output voltage setting is disabled when the input voltage is between 650V+3V or 900V-3V after start-up ’.
Why limit the adjustment range? This setting does not seem to be conducive to practical application. Is it possible to adjust the output voltage when I want to have a different input voltage? For example, if the input voltage is 700 V, the output is 530.4 V through the manual, but is it possible to set it to 300 V, what should I do if I can, and what will happen if not?
We look forward to hearing from you, thank you very much！
