Woodward SPM-D2-10B/PSY5-FU-D Automatic Synchronizer Unit

The Woodward SPM-D2-10B/PSY5-FU-D is a microprocessor-based automatic synchronizer designed for AC generator sets. It continuously monitors voltage, frequency and phase angle between generator and busbar, and outputs control signals to adjust speed and voltage to achieve safe paralleling operation.

This 24VDC powered version supports two switchable parameter sets and built-in synch-check logic. Equipped with LCD display and membrane keys for local parameter configuration, it can be programmed via Woodward ToolKit software. Widely used for power plant generator control cabinet maintenance and spare parts stocking.
