ESD5550/5570 Series – Isochronous, Droop & Variable Operation / Starting Fuel & Speed Ramping Adjust / Soft Coupling / Lead Circuit / Auxiliary Input & +10V Supply / Overspeed Contacts with Test & Rest
The ESD5550/5570 Series speed control unit is an all- electronic device designed to control engine speed with fast and precise response to transient load changes. This closed loop control, when connected to a proportional electric actuator and supplied with a magnetic speed sensor signal, will control a wide variety of engines in an isochronous or droop mode. It is designed for high reliability and built ruggedly to withstand the engine environment. The primary features of the ESD5550/5570 Series speed control unit are the engine STARTING Fuel and SPEED RAMPING adjustments. The use of these features will minimize engine exhaust smoke experienced prior to attaining engine operating speed.

ESD5300 Series – Isochronous, Variable, & Droop Operation / Dual Gain – Idle and Rated / Overspeed & Crank Termination / Speed Ramping / Starting Fuel Control / Power Drive Circuit / Adjustable PID Functions / Idle Speed Adjustment / Auxiliary Accessory Outputs / Unique Actuator Power Drive Circuit / Soft Coupling
The ESD5300 Series speed control unit is designed to precisely control engine speed and provide fast precise response to transient engine loads. This speed control is intended to 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 Volt DC power.
SSW Series – Repeatability Set Points / 12 or 24VDC Operation / Overspeed Test Function / Tachometer Output
SSW Series are respectively one, two, and three element electronic speed switches. They are powered by a DC battery supply and receive engine speed information from a magnetic speed sensor.
Both the SSW675 and SSW676 sense and signal a low speed setting (CRANK termination) and a high speed setting (OVERSPEED). The SSW676 has a third mid speed setting that can be used for several purposes such as parallel indication, underspeed, or general auxiliary contacts. The single element SSW674 has a wide range of adjustment and can be used for any one of these three functions.
ESD2200 Series – Isochronous Operation / Adjustable PID Functions / Speed Trim Pot / Hard Potted
The ESD2200 Series speed control unit is an all- electronic device designed to control engine speed with fast and precise response to transient load changes. This closed loop control, when connected to a proportional electric actuator and supplied with a magnetic speed sensor signal, will control a wide variety of engines in an isochronous or droop mode. It is designed for high reliability and it’s hard potted to withstand the engine environment.
