Hi there, I am trying to run a pump (see link ) that is operated by a DC motor. It is the NF 25 TTDCB-4 version. It needs a supply voltage between 10 and 28 V. I have a 24 V (1 A) DC power supply. The speed is controlled by a separate voltage signal (Vctrl) between 0 and 5 V. So far I connected my …
