Engineering Advantages
-
Optimized Low-Voltage Performance: The 9907-022 operates efficiently on an 18–40 VDC range. This makes it ideal for battery-backed industrial systems where voltage stability fluctuates during engine cranking.
-
Simplified Analog Tuning: This module utilizes manual switches and potentiometers for configuration. Engineers can set the 2000–6000 Hz speed range and fine-tune dynamic response without needing external software or laptops.
-
Rugged Sheet-Metal Construction: The chassis provides a sturdy frame that resists mechanical stress. Its design facilitates easy panel mounting while protecting the internal circuitry from physical impact in engine room environments.
-
Flexible Load Management: The unit seamlessly switches between isochronous mode for constant frequency and droop mode for load sharing. This flexibility allows a single spare part to support multiple engine configurations in a facility.
FAQs
What is the primary difference between the 9907-022 and other 2301A models?
The 9907-022 specifies a low-voltage input (18–40 VDC) and a high-frequency speed range (2000–6000 Hz). Always check your existing module's nameplate to match these electrical parameters exactly.
Can this module replace an older 2301A series unit?
Yes, provided the voltage and frequency ranges match. It retains the classic 2301A footprint, allowing for a direct physical swap-out without re-drilling mounting holes.
Is this a new or remanufactured part?
This is a 100% Brand New unit. It undergoes rigorous factory testing and arrives in original Woodward packaging, ensuring it meets all OEM performance standards.
Does it require special tools for installation?
No. You only need standard hand tools for wiring the terminal blocks and a small screwdriver for adjusting the tuning potentiometers.
