2301A Speed Control

The 2301A Speed Control controls the speed or load of diesel or gas engines, or steam or gas turbines. The unit provides control in the isochronous mode, with droop available through an externally wired potentiometer. The isochronous mode is used for constant speed of the controlled prime mover as long as it is able to provide power to satisfy the load. The 2301A Speed Control is compatible with Woodward SPM-A synchronizers, load sensors, and other power generation controls. These controls can be added to the system at any time, using the auxiliary or SPM inputs to the 2301A Speed Control. The 2301A Speed Control is available for forward- or reverse-acting applications, and can be used with single or tandem actuators. High voltage models accept 88 to 132 Vac or 90 to 150 Vdc, and low voltage models accept 10 to 40 Vdc supply for control power. 2301A Speed Controls are also available with 4–20 mA speed-setting input (see product specification 02301). Two Set Speeds The control has potentiometer-set Low Idle and Rated Speed settings which are selected with a switch.
