Overview
The ADC225 is a GAC external electric actuator for high-current applications. It is the heavy-duty variant of the ADC series, delivering up to 8 A for large diesel and gas generator engines.
Key Features
- Medium-Duty Electric Actuator — GAC external actuator for small diesel engines requiring precise fuel metering and fast response times
- 25° Angular Travel — Optimized stroke range for common fuel injection pump rack configurations on Perkins, Cummins, and Deutz engines
- Bidirectional Operation — Configurable push or pull action for flexible fuel pump rack interface without mechanical modifications
- Standard GAC Connector — Weatherproof 4-pin Deutsch connector with pre-wired harness for immediate integration with GAC ESD governor systems
- Durable Construction — Aluminum housing with sealed bearings rated for continuous-duty generator applications in harsh environments
- Governor Compatibility — Compatible with GAC ESD5500E, ESD5550E, ESD5111; KUTAI EG2000/EG3000; and Fortrust C2002 electronic speed governors
