Introduction
Sevcon Dragon8 controllers are designed to control 3-phase AC induction motors and Permanent
Magnet AC (PMAC) motors in battery and generator powered applications.
The controller adapts its output current to suit the loading conditions and the ambient temperature in
which it is operating (temporarily shutting down if necessary). It will also protect itself if the low voltage
circuits are incorrectly wired.
Signal wiring and power connections have been designed to be as simple and straight forward as
possible. Analog and digital signal inputs and outputs are provided for switches, sensors, contactors,
hydraulic valves and CAN communications. This I/O can be mapped to the CANbus for control by an
external VCU.
Configuration and control of Dragon8 is fully customizable using the latest version of Sevcon’s DVT, a
Windows based configuration software tool.
The state of the controller can be presented via a signal to a dashboard mounted light for example.
