Description
The Raymarine ACU-300 Actuator Control Unit (E70139) adapts the Evolution autopilot to solenoid-controlled electro-hydraulic steering. Rather than powering a reversing pump or mechanical drive, it switches the vessel's steering solenoids directly, with a maximum continuous output of 5 A and no clutch connection. It is equally suited to Raymarine and third party constant-running hydraulic drive systems.
The unit shares the larger ACU enclosure, 285 x 211.5 x 64.5 mm and 2.2 kg, accepts 12 or 24 V dc supplies over a 10.8 to 31.2 V dc range and feeds the SeaTalkng backbone with 3 A of fuse-protected power. A remote rotary rudder angle reference sensor is included with the ACU-300 and is an essential part of the system, which must run software v3.13 or later. The ACU-300 is supplied in the EV-300 Solenoid Pilot pack and works with the EV-1 Sensor Core, p70s and p70Rs heads and compatible Axiom chartplotters.
