Country of origin: Germany          Product weight：0.55kg

HS code：9032899099

Product Dimensions：

These controls are available for forward- or reverse-acting applications, and for use with either single or tandem actuators. Models for three different actuator current ranges are available, as well as a high-voltage model (90 to 150 Vdc or 88 to 132 Vac, 45 to 440 Hz), and a low-voltage model (20 to 40 Vdc). The high voltage model is identified as such on the front; the low voltage model is not.

In reverse-acting systems, the actuator calls for more fuel when the actuator voltage decreases. Complete loss of voltage to the actuator will drive the actuator to full fuel. This allows a backup mechanical ballhead governor to take control rather than shut down the prime mover as would a direct-acting system.

An optional deceleration ramp is also offered. When this option is present, the time to ramp from rated speed to idle speed is approximately 20 seconds. If this option is not present, this happens instantly.

Tables 1-1 and 1-2 show part numbers and features of all 9905/9907 series 2301A load sharing and speed controls.

These Woodward 2301A controls accept either a high-voltage or a low-voltage power source. The low voltage models operate on 20 to 40 Vdc, and the high voltage models operate on either 88 to 132 Vac or 90 to 150 Vdc. Both the lowand high-voltage models require a power capacity of 15 W minimum.

Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If you must remove the PCB from the control cabinet, follow these precautions:

. Do not touch any part of the PCB except the edges.

. Do not touch the electrical conductors, the connectors, or the 

components with conductive devices or with your hands.

. When replacing a PCB, keep the new PCB in the plastic antistatic 

protective bag it comes in until you are ready to install it. Immediately 

after removing the old PCB from the control cabinet, place it in the 

antistatic protective bag.

We have the same series of models in stock.  If you don't find the model you need, please contact us and we will provide you with an official quotation！
