Product Overview

The Woodward 8440-1019 SPM-D10 serves as a high-precision, microprocessor-based synchronizer for three-phase AC generators. This module automates the synchronization process by matching frequency, phase, and voltage across a single circuit breaker. It manages isolated and dead bus operations, ensuring safe and seamless connection to the power grid. We supply this unit as 100% Brand New original equipment to ensure maximum safety and accuracy for your power generation control system.

Technical Specifications

Engineering Advantages

• Universal Power Compatibility: The 8440-1019 supports a broad AC/DC input range (90–250 VAC / 120–375 VDC). This flexibility allows the unit to operate in diverse global power infrastructures without additional voltage converters.

• Dual Synchronization Modes: The module executes either phase match or slip frequency synchronization. This choice allows engineers to optimize the connection speed versus the mechanical stress on the generator set.

• Robust Surge Protection: With a surge rating of up to 4.0 kV (for 400V systems), the unit survives the high-voltage transients common in industrial switchgear environments.

• Simplified Front-Panel Interface: Users configure parameters directly via the front LCD or through a PC link. Password protection prevents unauthorized adjustments to critical sync-check settings.

• Standardized DIN Mounting: The 144 x 72 mm housing fits standard industrial panel cutouts. This minimizes installation time and ensures compatibility with existing console layouts.

FAQs

Can the 8440-1019 handle dead bus closure?

Yes. The unit includes specific logic to detect a dead bus and issue a close command to the breaker when the generator is ready, facilitating black-start operations.

What parameters does the raise/lower output control?

The unit provides discrete outputs to signal the engine governor (speed) and the automatic voltage regulator (AVR) to bring the generator into alignment with the bus.

Is this product brand new?

Yes. We guarantee this Woodward 8440-1019 is 100% Brand New. It ships in original factory packaging to maintain complete hardware integrity and software calibration.

How does the synchroscope help during commissioning?

The integrated digital synchroscope provides real-time visual feedback of the phase relationship. This allows onsite technicians to verify the synchronization logic before enabling automatic breaker closure.
