Product Description
The 9907-173 REV B load sharing module from Woodward manages generator load distribution in multi-engine power systems.
This controller balances electrical load between parallel generators while maintaining stable system frequency and engine speed.
The 9907-173 REV B module supports both isochronous load sharing and droop load sharing control strategies.
Therefore, operators maintain balanced generator output and avoid overload conditions across distributed power generation equipment.
Industrial facilities frequently integrate 9907-173 REV B with Woodward governors, synchronizers, and generator control systems.
