แผงควบคุมความเร็วรอบ รุ่น ESD5200 Series เป็นแผงวงจรอิเล็คทรอนิคส์ที่รวมฟังชั่นการทำงานของรุ่น ESD5100 Series ทั้งหมด เพิ่มเติมในส่วนของฟังชั่นจำกัดความเร็วรอบ (Speed Limit) เข้าไปด้วย

The ESD5221 Series speed control unit is designed to precisely control engine speed with rapid responses to transient load changes. The ESD speed control is compatible with all GAC proportional actuators except the ACB2001 electric actuator since this high torque actuator also requires current limiting. Ruggedly built to withstand all engine environments, the ESD will control a wide variety of engines in an isochronous or droop mode.
