Model 8290-074 is from the Woodward manufacturer, and works as a speed control device in an EPG system. This device is in the Electrically Powered Governor series and has been discontinued. Adding this model to an actuator and magnetic pickup makes an EPG system that can be used with prime movers. These systems do not require the use of a hydraulic supply or mechanical drive, making them simple and easy to operate. Product 8290-074 can be used with actuator models 8256-021 and 8256-016 and is only compatible with gas or gasoline prime movers. It uses a 24-volt system battery voltage, with a steady-state-current consumption maximum of 3 amps.
The speed range for this model is 1500 to 3000 Hz, and the operating temperature should remain between -40 and 167 degrees Fahrenheit. This device can be mounted directly on the prime mover but should be in a protected area away from moving parts and high-heat products. It should also be installed with plenty of ventilation, and close to the actuator and battery of the mover. While Woodward has discontinued model 8290-074 it is available through AX Control. AX Control can sell, buy, or repair this speed control device.
