8280-412

Product Overview Woodward 8280‑412 is a low‑voltage 723PLUS digital speed & load‑sharing controller (DSLC‑compatible) for diesel/gas/dual‑fuel reciprocating engines. It delivers precision speed regulation, real‑kW load sharing, synchronization, and engine protection for power generation, marine propulsion, gas compression and industrial prime‑mover systems. It supports dual magnetic pickup (MPU) speed inputs and flexible communication for multi‑genset parallel control.
