Woodward 9907-014 2301A Speed Controller

Woodward 9907-014 is a 2301A series electronic speed controller dedicated for prime movers including gas engines, diesel engines and small steam turbines. It receives speed signals from magnetic pickup sensors and outputs actuator drive signals to maintain stable rotating speed under varying load conditions.

This unit supports isochronous and droop control modes without load sharing function. It is equipped with adjustable front panel potentiometers for on-site tuning. Powered by 20–40 VDC, it is widely supplied as replacement spare parts for generator sets, compressor drives and industrial prime mover control systems.
