Product Description

The 9903-543 is an Automatic Generator Loading Control (AGLC) module developed by Woodward, Inc. for precise power transfer management during generator synchronization and loading operations.

The module ensures smooth ramp-up and ramp-down loading of synchronous generators, preventing mechanical stress on prime movers and maintaining electrical stability during grid connection or disconnection. It supports base loading, load sharing, and process control modes, making it suitable for both utility and industrial power management systems.

Its rugged industrial design supports high-vibration environments such as engine rooms, containerized generator sets, and distributed power plants.

FAQ

Can it be used for utility paralleling?
Yes. It supports paralleling with an infinite bus and maintaining stable base load operation.

Does it require a separate power supply?
It can share a 24V DC supply, but filtered DC power is recommended to reduce signal noise.

Are ramp rates adjustable?
Yes. Ramp-up and ramp-down rates can be independently configured to match different engine response characteristics.
