ESD5330 | Speed Controls

The GAC ESD5330, part of the ESD5300 Series, is a 24 V DC speed control unit designed to precisely control engine speed and provide fast, precise response to transient engine loads. It is compatible with all GAC actuators, including the ACB2001, and forms a complete closed-loop control system when paired with a magnetic pickup sensor and 24-volt DC power. It features a two-element speed switch, speed ramping from idle to operating speed, starting fuel control for lower engine exhaust emissions, a unique actuator power drive circuit, accessory inputs for load sharing, variable speed governing, and protection against both reverse battery voltage and transient voltage.
