Detailed Description

The Woodward 9907-175 Load Sharing Module is engineered for advanced control systems that require precise load sharing functionality. It facilitates smooth integration between Caterpillar engines and Woodward-controlled engines, ensuring optimized power management. This module comes with a versatile power supply that operates within a voltage range of 18 to 32 VDC, consuming approximately 5 Watts of power.

With robust protection mechanisms in place, the 9907-175 safeguards against under-voltage, over-voltage (beyond 80 VDC), and reverse voltage (down to -32 VDC). It also features three-phase PT inputs, designed for line-to-line operation at 100 to 240 V/AC. The PT input burden is rated at 1.5 to 1.7 VA per phase at 240 V/AC and 0.4 to 0.5 VA per phase at 120 V/AC, making it highly efficient for varying input conditions.

The module’s compact dimensions of 273.6 x 214.1 x 59.2 mm (10.8 x 8.4 x 2.3 inches) ensure easy integration into most industrial control systems. Its beige exterior offers durability, although the unit is not suitable for environments with high humidity or dust. This makes it ideal for controlled environments in industrial applications where load sharing is crucial.

Applications

Industrial Automation: Perfect for systems requiring precise load sharing across engines with different controllers.
Power Systems Control: Helps manage power distribution in complex multi-engine setups.
Marine and Heavy Machinery: Ideal for use with Caterpillar engines and Woodward components in demanding environments.
