        Features:

        • Serves as the Power Interface Between AC Input and the 3300 Rack Backplane
        • Performs AC/DC Power Conversion with Integrated Line Noise Filtering
        • Powers Up to 12 Standard 3300 Monitors and Their Associated Transducers
        The Bently Nevada 3300/12 AC Power Supply Module serves as the critical interface between the universal AC power source and the 3300 rack backplane, delivering reliable DC power to all connected monitors and transducers within the system. The 3300/12 combines AC/DC power conversion capability with integrated line noise filtering, ensuring clean and stable power distribution throughout the rack. It operates in conjunction with all standard 3300 series monitors and their associated proximity transducers, providing a unified power solution for complete machinery protection systems.

        The 3300/12 AC Power Supply Module operates as the primary power source in a 3300 rack, continuously converting incoming AC power (115 Vac or 220 Vac) into regulated DC voltages used by the monitors installed in the rack. The 3300/12 distributes this converted power through the rack backplane to support steady state operation of all connected modules and transducers. Unlike systems requiring redundant power configurations, the 3300/12 is designed so that a second power supply in the same rack is never required, simplifying installation and reducing system complexity while maintaining reliable power delivery.

        The 3300/12 provides essential power functions common to the entire 3300 rack, and is a critical component of the monitoring path, directly affecting the proper, normal operation of the overall monitor system. One 3300/12 power supply is required per rack, as the module is engineered to fully support up to 12 monitors and their transducers without additional power units. The 3300/12 occupies the left-most location (position 1) in the 3300 rack, which is the dedicated power supply slot, ensuring optimal power distribution to all installed monitoring modules.

        The 3300/12 Bently Nevada AC Power Supply Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The Bently Nevada 3300/12 AC Power Supply Module is a dedicated power supply unit designed specifically for delivering stable and regulated DC power to Bently Nevada 3300 series monitoring systems. This 3300/12 power supply module addresses the critical need for reliable power distribution in industrial machinery protection systems, ensuring consistent operation of up to 12 monitors and their associated transducers without requiring additional power units.

        The 3300/12 AC Power Supply accepts either 115 Vac or 220 Vac input and efficiently converts it into the necessary DC voltages required by the monitors installed within the rack. As standard equipment, the 3300/12 module includes a built-in line noise filter, which enhances power quality and protects connected monitoring instruments from electrical interference commonly found in industrial environments.

        Designed for seamless integration, the 3300/12 AC Power Supply Module is installed in the left-most position (position 1) of a standard 3300 rack. This specific placement ensures optimal power distribution to all connected modules. Notably, a second power supply in the same rack is never required when using the 3300/12, simplifying rack configuration and reducing system complexity.

        The 3300/12 AC Power Supply Module is widely applied in critical industrial sectors including oil and gas, power generation, chemical processing, and heavy manufacturing. It serves as an essential component in machinery condition monitoring and protection systems, supporting vibration monitoring, thrust position measurement, and other key machinery health parameters that require uninterrupted power delivery.
