Overview
The ADC120 is a GAC external electric actuator designed for precise fuel rack positioning in diesel and gas generator engines. It is a compact, commercial-connector actuator for engines in the 100–500 kW range.
Key Features
- 1.0 lb-ft Torque Output — GAC external electric actuator with 25° angular travel for small to medium fuel injection pump racks
- <35ms Response Time — 10%–90% stroke in under 35ms for rapid fuel corrections and stable engine speed under transient loads
- Commercial-Grade Connector — Weatherproof Deutsch-style electrical connector with pre-terminated wiring harness for plug-and-play installation
- Universal Mounting Bracket — Adjustable mounting flange compatible with Cummins, Perkins, Deutz, and other industrial engine fuel pumps
- Bidirectional Operation — Supports both push and pull fuel rack configurations for maximum application flexibility
- Compatible with GAC ESD Governors — Designed for GAC ESD-series electronic speed governors (ESD5500E, ESD5550E, S6700H)
