Woodward 8440-1884 easYgen-2500-5/P1 Generator Controller

Overview

The 8440-1884 (also known as easYgen-2500-5A/P1) is a microprocessor-based generator controller. It supports automatic start/stop, synchronization, load sharing, and full engine-generator protection. This controller handles both island and utility-parallel operations, making it ideal for standby, prime, and distributed generation systems. It manages up to 16 gensets in parallel. Operators can choose flexible modes like Auto, Manual, Stop, Load Test, or No Load Test. The graphical LCD display ensures clear status visualization. Remote monitoring is available via analog/digital inputs and communication ports.
