 9905-026 Functional Description 

The Woodward 9905-026 is a low-voltage, forward-acting member of the 2301A series of load sharing and speed controls. This particular model requires a power supply of 20-40VDC and consumes 15W or less of power. This model uses a single actuator with a current range of 0-20mA. Since this is a forward-acting model, the actuator will be driven to empty fuel in the event that full loss of voltage is detected.

Features and benefits

The 9905-026 can be operated in isochronous mode or droop mode in order to accommodate a wide variety of prime mover and bus configurations. This model does not come with a deceleration ramp. The 9905-026 requires some other equipment to set it up as a fully-functioning 2301A series system. In addition to the control itself, operators need a 20-40VDC power source, a proportional actuator for positioning the fuel-metering device, and load-measuring current and potential transformers.
