The ESD5200 Series speed control unit is designed to precisely con-

trol engine speed with rapid responses to transient load changes. The 

ESD5221 is compatible with all GAC proportional actuators except the 

ACB2001 electric actuator. 

Ruggedly built to withstand all engine environments, the ESD can 

control a wide variety of engines in an isochronous or droop mode.  

Capabilities include:

• 

Overspeed Switch and LED Indicator

• 

Selectable Droop Operation

• 

Adjustable Idle Current

• 

Auxiliary Accessory Input

• 

Reverse Voltage Protection

• 

Single Element Speed Switch

• 

Speed Anticipation
