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.
ESD5200 Series – Speed Anticipation Circuit / Adjustable PID Functions / Reverse Voltage Protection / Overspeed Contact
The ESD5200 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.
ECC Series – Genset Voltage Frequency / Isochronous Speed Control / Full PID Setting / Designed to Govern from Frequency Signal of an AC Generator / No Magnetic Speed Pickup Needed
The ECC speed control unit is an electronic device designed to control engine speed with precise response to transient engine loads changes. The closed loop speed control, when connected to a proportional actuator and supplied with a speed signal/ frequency from the main AC generator, will control a wide variety of engines in an isochronous mode. The speed signal input must be in the frequency range of 40 to 80 Hz.
ESD5500-II Series – Suitable for Both Gaseous & Diesel Applications / Light Force & Standard Actuators / Selectable Dither Function / LED Indicators
The next generation of GAC’s Speed Controllers, the ESD5500-II Fusion Series combines all of the most popular functions of the various ESD5500 Series (5500, 5520, 5526 & 5528) into a single, high-performance unit. The ESD5500-II speed control unit is designed to precisely control engine speed with rapid responses to transient load changes. The ESD5500-II speed control is compatible with all GAC proportional actuators except the ACB2001 electric actuator since this high torque actuator also requires current limiting available in the ESD5300 Series. Ruggedly built to withstand all engine environments, the ESD5500-II has all the same well known features of the ESD5500 and also incorporates selectable light-force for low current actuators, dither for difficult engines with respect to stability and integrated anti-windup for both diesel and gaseous application.
