SPECIFICATIONS
The ESD5300 Series Speed Control units are designed to precisely
control engine speed and provide fast, precise response to transient
engine loads. The ESD5330 and 5340 speed control can be used with
all GAC Actuators, including the ACB2001. A complete, closed-loop
control system is formed with the addition of a magnetic pickup signal
sensing engine speed and 24 V DC power.
◊ Two-element speed switch
◊ Speed ramping idle to operating speed
◊ Starting fuel control for lower engine exhaust emissions
◊ Unique actuator power drive circuit
◊ Accessory inputs for load sharing
◊ Variable speed governing
◊ Protection against reverse battery and transient voltage
◊ Advanced startup circuit for large-bore engines (ESD5340)
