E70100
The ACU-400 is the most powerful Evolution actuator control unit, driving Type 2 and Type 3 hydraulic, hydraulic linear, mechanical linear and rotary drives. It delivers up to 30 A continuous drive current from a 12 or 24 volt supply and powers the SeaTalkng bus. Combine with an EV-1 Sensor Core, a p70s or p70Rs head and a Type 2 or Type 3 drive for large sail and power vessels.

Description

The Raymarine ACU-400 Actuator Control Unit (E70100) sits at the top of the Evolution range, built for the Type 2 and Type 3 drives fitted to larger sailing yachts and powerboats. Maximum continuous drive output is 30 A, with a 4 A continuous clutch output configurable for 12 or 24 V clutches on either supply voltage. The enclosure measures 285 x 211.5 x 64.5 mm and weighs 2.2 kg.

Officially compatible drives span the Type 2 and Type 3 hydraulic pumps, Type 2 and Type 3 hydraulic linear drives, the Type 2 mechanical linear drive and the Type 2 rotary drive. The unit accepts 12 or 24 V dc supplies across a 10.8 to 31.2 V dc range and feeds the SeaTalkng backbone with 3 A of fused power. It is supplied in the EV-400 Sail and EV-400 Power packs together with a rotary rudder reference sensor, and is controlled from a p70s or p70Rs head or a compatible Axiom chartplotter. Raymarine has issued a product recall notice affecting certain ACU-400 units; contact us with your serial number for guidance.

Which ACU does my boat need?
Match the ACU to the drive: the ACU-100 runs the Evolution wheel and tiller drives and the Type 0.5 hydraulic pump; the ACU-150 runs Type 1 12 V hydraulic pumps (80 to 230 cc rams); the ACU-200 runs Type 1 hydraulic, mechanical linear and rotary drives; the ACU-300 is for solenoid-controlled steering; and the ACU-400 runs Type 2 and Type 3 drives.
Does an Evolution autopilot need calibration?
No. Set-up is automatic: the rudder gain, rudder damping, counter rudder and compass calibration routines required by earlier autopilots are no longer necessary, and the system keeps refining itself as you use the boat. This is documented in the EV-1 installation instructions (87472).
Do I need a rudder angle reference sensor?
Raymarine highly recommends the rudder angle reference transducer (M81105) on every Evolution system for optimum performance, and it is essential on ACU-300 solenoid installations. The EV-400 Sail and Power packs include a rotary rudder feedback unit, and the ACU-300 ships with one.
Does the ACU power the SeaTalkng network?
The ACU-200, ACU-300 and ACU-400 feed the SeaTalkng backbone with 3 A of fuse-protected 12 V power. The compact ACU-100 and ACU-150 do not power the backbone; it needs its own 12 V feed.
Can I control the autopilot from my chartplotter?
Yes. Compatible controllers include the Axiom, Axiom+, Axiom Pro, Axiom 2 Pro, Axiom XL and Axiom 2 XL chartplotter families as well as the p70s and p70Rs pilot heads. Axiom 2 Pro and Axiom 2 XL need LightHouse 4 v4.4.70 or later; earlier families are supported per the compatibility tables in document 87472.
