Raymarine ACU-100 Actuator Control Unit

Description

The Raymarine ACU-100 Actuator Control Unit is a compact 12V drive controller for Raymarine Evolution autopilot systems using a wheel drive, tiller drive, or Type 0.5 hydraulic pump. It provides the main power and drive electronics between a compatible steering actuator, EV-1 sensor core, p70-series control head, and the SeaTalkng network. This is an actuator control unit only, not a complete autopilot system.

The ACU-100 provides up to 7A continuous drive output and operates from 10.8V to 15.6V DC. It measures 180 mm wide by 140 mm high by 52 mm deep, weighs 0.6 kg, and requires dry internal mounting. A SeaTalkng spur-to-bare-wire cable is supplied, while the selected steering drive, EV-1 sensor, control head, power circuit, and network components must be added separately.

Key Specifications

• 12V actuator control unit for compatible Raymarine Evolution autopilot systems.
• Designed for wheel drives, tiller drives, and Type 0.5 hydraulic pumps.
• Provides up to 7A continuous drive output at supply voltage.
• Operates from 10.8V to 15.6V DC with 300mA standby power consumption at 12V.
• Connects to the Evolution system through SeaTalkng networking.
• Uses direct motor screw terminals for the selected steering drive.
• Measures 180 mm by 140 mm by 52 mm and weighs 0.6 kg.
• Has IPX2 protection at the connector panel and IPX6 protection for drive electronics; install in a dry protected internal location.

System Integration

The ACU-100 requires a compatible EV-1 sensor core, p70s or p70Rs control head, SeaTalkng network, and correctly matched wheel, tiller, or Type 0.5 hydraulic drive. It must not be used with a Type 1 or larger hydraulic pump, high-current linear drive, rotary drive, or actuator that exceeds its 7A continuous output rating.

Select the steering actuator based on the vessel steering type, displacement, drive current, cylinder volume where relevant, and manufacturer-approved Evolution compatibility. Use a higher-capacity ACU when the selected drive requires more than 7A continuous output.

Installation Considerations

Mount the ACU-100 in a dry, accessible interior location with adequate clearance for power, drive, and SeaTalkng wiring. Use marine-grade conductors and appropriate circuit protection for the selected actuator, keep high-current wiring separate from sensitive network and compass cables, and verify motor direction during commissioning. Follow Raymarine dockside setup and sea-trial procedures after installation.

Before Ordering

Confirm a compatible Raymarine Evolution system, EV-1 sensor core, p70s or p70Rs control head, wheel or tiller drive or Type 0.5 pump, 12V supply, 7A continuous drive requirement, SeaTalkng network, dry ACU mounting space, suitable wiring, circuit protection, and complete autopilot-system components before purchase.
