Curtis 1239E-8521


These controllers power the Motenergy motors with Sine/Cosine encoders - like the ME1115, ME1302, ME1616, ME1507.  Ask us about building a complete system so you don't have to worry about making the wiring harness or programming. These controllers will not work off the shelf without motor characterization via the OEM level pc based programming software. If you are not experienced with this part of the process, please purchase an entire kit that comes ready to go, as we can't offer tech support for motor configuration.
