ESD5330

Isochronous, Variable, & Droop Operation / 2 Element Speed Switch / Speed Ramping / Stating Fuel Control / Dual Gain / 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.
