The ACU-400 (Actuator Control Unit) is a key component for Evolution autopilot systems. The ACU-400 houses the main power and drive electronics for direct connection to your vessel’s steering system and 12-volt DC electrical source. Combine with an EV-1 sensor, autopilot control head, and Type 2 and Type 3 hydraulic, mechanical linear, hydraulic linear, or mechanical rotary drive a complete autopilot system.
