Data Sheet

8 RGDC18xx Motor Controller Datasheet Version 1.5 January 17, 2018
Measured Amps
Including Amps sensors on the wires allows for a fast and efficient feed of information. The controller has sep-
arate built in sensor for measuring the battery amps and the motor amps. Both motor amps and battery amps
are measured in real time.
