Raymarine ACU-150 Actuator Control Unit

Description

The Raymarine ACU-150 Actuator Control Unit is a 12V autopilot drive controller designed for compatible Raymarine Evolution systems using a Type 1 hydraulic pump. It connects the EV-1 sensor core and p70Rs control head to the steering pump through SeaTalkng and direct motor terminals. The ACU-150 is intended for hydraulic steering cylinders from 4.9 to 14 cubic inches when paired with the correct Type 1 drive system.

The ACU-150 provides up to 12A continuous drive output and is commonly specified with a 15A peak-load planning limit for Type 1 hydraulic pump installations. It measures approximately 180 mm by 140 mm, weighs 0.6 kg, and uses a reinforced ABS enclosure with IPX2 drip protection. Because the ACU-150 is an actuator-control component, it must be mounted in a dry protected interior location and used with separate Evolution sensor, control head, pump, hydraulic plumbing, and power hardware.

Hydraulic Installation

The ACU-150 does not include a pump, sensor core, control display, hoses, fittings, hydraulic fluid, or steering-cylinder hardware. Confirm the actual cylinder volume is within the Type 1 pump range, then select pump fittings, hose size, routing, isolation valves, electrical protection, and ACU wiring to match the vessel’s hydraulic steering system.

Mount the unit vertically in a dry accessible location away from bilge water, direct spray, excessive heat, and vibration. Protect the 12V supply with the correctly sized breaker or fuse, route pump cables carefully, and verify motor direction during commissioning. Follow Raymarine’s installation procedures for SeaTalkng wiring, hydraulic connection, dockside setup, and sea-trial calibration.

Before Ordering

Confirm a compatible Raymarine Evolution system, Type 1 hydraulic pump, steering-cylinder volume from 4.9 to 14 cubic inches, 12V supply, required pump current, ACU-150 dry mounting space, SeaTalkng network, EV-1 sensor location, p70Rs or compatible control display, hydraulic fitting and hose requirements, and complete installation hardware before purchase.
