This heavy-duty power supply is engineered to provide stable, regulated DC voltages to the entire rack backplane, supporting up to 12 monitoring modules and their connected field sensors. Occupying the primary leftmost slot of the chassis, it eliminates the need for redundant power units due to its high-capacity design. This specific configuration utilizes a dual-voltage input architecture, allowing for field selection between 115 Vac and 220 Vac. By providing clean, noise-filtered power, the 3300\/10 ensures that vibration and displacement measurements remain accurate and free from electrical interference.\u003c\/p\u003e\n\u003ch3\u003eElectromechanical Attributes and Hardware Parameters\u003c\/h3\u003e\n\u003cp\u003eThe 3300\/10-02-02-00 is built to sustain continuous operation in high-demand industrial environments, featuring a robust physical footprint and high-efficiency heat dissipation.\u003c\/p\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOrder Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e3300\/10-02-02-00\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eAlternate Part Number:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e78422-01\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e95 to 125 Vac or 190 to 250 Vac (Selectable)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInput Frequency:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e47 to 63 Hz\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eStandard Rack Position:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eSlot 1 (Primary power location)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Regulation:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePrecision DC conversion for transducer and monitor excitation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConnector Type:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ePositive-retention security connectors for high-vibration stability\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eModule Mass:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e1.52 kg\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePhysical Dimensions:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e24.1 cm x 5.1 cm x 24.4 cm\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eIntegrated over-current and surge protection\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eOperating Temperature:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e-30°C to +65°C (-22°F to +149°F)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eCertification:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCompatible with API 670 standards for machinery protection\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOperational Deployment Scenarios\u003c\/h3\u003e\n\u003ch3\u003eCritical Power for High-Speed Turbomachinery\u003c\/h3\u003e\n\u003cp\u003eIn power generation facilities, the 3300\/10-02-02-00 provides the necessary excitation voltage for Proximitor sensors on steam and gas turbines.
