About the 9905-035

Summary

The 9905-035 is a high-voltage load sharing and speed control in the 2301A series from Woodward. This model is reverse-acting and uses a tandem actuator system with a current of 0-200mA. This model may be used in either isochronous or droop mode. A power input of 90-150VDC or 88-132VAC is needed to supply this unit. This unit is compatible with other Woodward devices such as the SPM-A series synchronizers.

Functionality

The 9905-035 has speed and load sensing capabilities to help it function. Load sensing can be accomplished by connecting current and potential transformers to the 90-240VAC 3Ø, 45-66Hz 3Ø input. For speed sensing, the 9905-035 uses a magnetic pickup with a minimum voltage of 1VAC and a maximum of 30VAC. The input impedance of this speed sensor input is between 100-300 ohms.

Miscellaneous Information

The 9905-035 uses 0-6VDC power for load sharing and has a load gain maximum of 6VDC at 5A of CT current. The actuator output of this model is maximum 7.5VDC for 0-214mA with 35 ohm coil. The 9905-035 has a +/-5VDC input for changing speed with SPM-A synchronizers from Woodward. The unit is a single PCB housed in a sheet metal chassis and weighs approximately 1.8 kgs, or 4 lbs.

Reviews For 9905-035

Internal Review
(5.0)

The 9905-035 is a good control if you are looking for a reverse-acting tandem actuator system. The detected voltage in the actuator system is inversely proportional to the calls for fuel. If you have something like a mechanical ballhead governor, this will allow your system to continue running rather than shut down in the event of a lost voltage signal. -AX Control Lead Technician
