FUNCTIONAL DESCRIPTION:
The 8923-811 is a Transient Voltage Surge Suppressor Kit designed and manufactured by Woodward to protect sensitive electronic control systems from electrical transients and voltage spikes. In industrial and marine environments, electrical noise and sudden voltage surges, often caused by lightning, heavy motor switching, or alternator load dumping, can damage the microprocessor-based logic of turbine and engine governors. This kit provides a critical layer of defense to ensure long-term hardware reliability.
VOLTAGE SPIKE MITIGATION
The primary role of the Transient Voltage Surge Suppressor Kit (12V) is to monitor the incoming DC power line and clamp any voltage that exceeds the safe operating threshold for 12V systems. By diverting excess energy away from the internal components of the controller, the suppressor prevents semiconductor failure and data corruption. This is particularly vital for systems running on battery-charging circuits where cranking transients or charger failures can cause significant voltage fluctuations.
VERSATILE SYSTEM PROTECTION
While often categorized alongside 2301A or 723 series accessories, the Transient Voltage Surge Suppressor Kit (12V) is a versatile protection module compatible with a wide range of Woodward electronic controls. It is typically installed at the power input terminals of the control chassis. Its small form factor allows it to be integrated into existing wiring harnesses or terminal strips without requiring extensive cabinet modifications.
RUGGEDIZED FOR INDUSTRIAL USE
The Transient Voltage Surge Suppressor Kit (12V) is built to withstand the harsh conditions found in engine rooms and power plants. The suppression components are selected for their high energy-handling capability and rapid response times (measured in nanoseconds). This ensures that even the fastest-moving electrical transients are neutralized before they can penetrate the control system's power supply.

What is the Woodward 8923-811?
The 8923-811 is a 12V transient voltage surge suppressor kit. It is designed to protect Woodward electronic controls from damage caused by electrical surges and spikes on the power supply line.
Can this kit be used on a 24V system?
No. The Transient Voltage Surge Suppressor Kit is specifically rated for 12V nominal systems. Using it on a 24V system would cause the suppressor to clamp the normal operating voltage, potentially leading to a short circuit or damage to the suppressor itself. For 24V applications, a corresponding 24V kit must be used.
Where should the 8923-811 be installed?
For maximum effectiveness, the suppressor should be installed as close as possible to the power input terminals of the control module (e.g., the 2301A or 723plus). This ensures that any transients picked up along the cable run are suppressed before they enter the device.
Is this kit compatible with non-Woodward equipment?
While specifically designed for Woodward systems, the Transient Voltage Surge Suppressor Kit provides general 12V DC surge suppression and can technically be used to protect other sensitive 12V industrial electronics, provided the current ratings and application requirements align.
