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.
