Napájecí jednotka ACU-400

The ACU-400 power drive is an actuator control unit dedicated to Raymarine Evolution autopilot systems. It serves as the essential interface between the EV-1 core sensor, control heads (such as p70, p70s, p70R, p70Rs) or multifunction displays (MFD), and the vessel's steering actuator. It is specifically designed for installations requiring high power management for steering.

The ACU-400 is compatible with a wide range of steering drive systems, ensuring versatility for various vessel configurations. It supports the following actuator types:

Linear actuators Type 1 and 2Linear hydraulic systems Type 2 and 3I/O Stern drivesSport DriveVeradoRotary drives Type 1 and 2Hydraulic pumps Type 1, 2 and 3

The physical dimensions of the ACU-400 housing are 284.9 mm x 261.0 mm, with a height of 59.6 mm. A minimum clearance of 50 mm is required around the unit for proper installation and cable routing.

The ACU-400 integrates directly into Raymarine's SeaTalk NG network. This connection enables communication and data distribution between all components of the Evolution autopilot system, including the EV-1 core sensor, control heads, and multifunction displays, ensuring smooth and fast information exchange.

The ACU-400 housing is designed to work with the following Raymarine autopilot control heads:

It is also compatible with Raymarine multifunction displays (MFD) that can be used as autopilot controllers, enabling full integration into your navigation system.

The ACU-400 is positioned as the most robust solution in the ACU series (which also includes the ACU-100, ACU-150, ACU-200, and ACU-300). While the ACU-100 and ACU-150 are designed for low to medium power applications, the ACU-400 is specifically sized for high-current steering actuators. It is ideal for high-capacity hydraulic pumps or powerful linear actuators, essential for maintaining precise and responsive autopilot control on boats with higher steering power demands.

Commissioning a Raymarine Evolution autopilot system with the ACU-400 involves the following steps:

Powering on all components of the autopilot system.Selecting the vessel's hull type via the controller menu.Using the dockside calibration assistant (Dockside wizard) to configure basic parameters.Selecting the steering drive type.Checking the rudder alignment (for systems with rudder angle sensor).Setting the rudder limit.Checking the rudder drive.If no rudder angle sensor is installed, specify the hard-over time.Performing compass linearization.

Yes, for optimal and safe operation, the ACU-400 power unit requires a dedicated grounding connection. It is essential to use a dedicated drain wire for this grounding connection.
