EPS-D0 / EPS-D0C

							Voltage：24V  & 20s output Current Rating (Arms):70A

EPS-D0 / EPS-D0C is an efficient and secure DC brushed permanent magnet motor controller used for Electric Power Steering (EPS).EPS-D0C serves as a steering system controller, interpreting steering commands input from external sources and feedback from wheel positions. It then drives the steering motor to move the steering wheel to the desired position.
EPS-D0 / EPS-D0C is compatible with the corresponding communication protocol of the DALA AC traction controller. During startup, it needs to 'handshake' with the traction controller to enable certain functions. It can also operate independently to perform the steering function.
