AGLC Voltage Regulator & Load Manager | Woodward 9905-096

Product Overview

The Woodward 9905-096 Automatic Generator Loading Control (AGLC) provides critical voltage regulation and load management for industrial and utility-scale power systems. This module automates the complex process of load sharing between multiple generators or between a generator and the utility grid. We supply this unit as 100% Brand New factory stock, ensuring your power infrastructure benefits from a rugged, high-precision controller designed to maximize system efficiency and prevent electrical instability.

Technical Specifications

The 9905-096 features a hardened hardware profile designed to maintain consistent output under extreme electrical and mechanical stress.

Engineering Advantages

• Precision Grid Paralleling: The 9905-096 coordinates seamlessly with Woodward governors to manage smooth load transitions when paralleling with a utility bus. It prevents power surges and mechanical transients that typically occur during manual synchronization.

• Superior Mechanical Durability: Featuring a rugged metal chassis and a 60G shock resistance rating, this module thrives in marine engine rooms and heavy industrial sites where high vibration levels frequently cause standard controllers to fail.

• Extreme Thermal Resilience: This unit maintains an accuracy class of 0.5 even while operating in temperatures as high as +85°C. This wide thermal window eliminates the need for expensive specialized cooling in most outdoor or desert-based power enclosures.

• Automatic Load Balancing: The AGLC logic continuously monitors the generator output and adjusts the fuel demand via the governor. This ensures that every generator in a multi-unit lineup carries an equal percentage of its rated load, optimizing fuel consumption across the fleet.

• Voltage Stability Management: Beyond simple load sharing, the 9905-096 assists in regulating the generator's voltage output. It dampens fluctuations caused by sudden large-motor starts or grid-side impedance changes.

FAQs

Q: What is the primary difference between the 9905-096 and a standard speed governor?

A: A governor controls the engine's RPM, whereas the 9905-096 AGLC specifically manages how much "work" or load the generator takes from the system. It works in tandem with the governor to ensure the generator contributes power to the grid without overloading the engine or causing reverse-power trips.

Q: Can I install this unit in a marine environment?

A: Absolutely. The 9905-096's metal chassis and exceptional 60G shock resistance meet the demanding requirements of marine propulsion and auxiliary power systems where engine vibration is constant.

Q: Does this module require specialized configuration software?

A: The AGLC series typically utilizes hardware-based potentiometers and switches for calibration. This allows field engineers to perform precision tuning using only a voltmeter and frequency meter, without the need for proprietary laptop software at the installation site.

Q: Is the 9905-096 compatible with non-Woodward governors?

A: While optimized for Woodward's ecosystem (like the 2301A or ProAct series), the 9905-096 can interface with many third-party governors that accept a standard voltage or current bias signal for speed/load offset.
