Product Description
The 9907-250 is a control module that is useful for dealing with load sharing and speed controlling. In regards to installation with engines dealing with torque converters, as well as split shaft gas turbines. Two control units are used to maximize efficiency, as there are plenty of tasks that would overload a single controller unit. The best way to demonstrate this for example is that if there were only one control unit it would be inadequate when responding to role changes. Also, a great deal of instability can be expected, when only controlling the speed of an isolated load there lies a danger of overspeeding the prime mover which can be a causation to failure.
Some features of the 9907-250 to note are as follows. The first to note is the Magnetic Pickups or MPUs, which connect both speed controls which in turn control the flow of fuel. Also, there is a Speed Sensor that works to make sure that the shield within the unit is insulated from all other conductors that are part of the MPU. The Actuator connects to wire terminals 20(+) and 21(-), its time constant compatibility ranges from 0-500 ms. The Vibration of the 9907-250 is 4Gs, to 5-500 Hz. Also, there is a wide range of speed selection from 500-12,000Hz. AX Control INC is well suited in terms of Buying, Reselling, and Repairing this as well as many other Woodward parts.
