        Features:

        • Receives External High-Voltage DC Power And Feeds Internal Modules
        • Supports Primary And Backup Power Supply Configurations
        • Ensures Continuous Rack Operation During Module Replacement
        The Bently Nevada 115M7750-01 High Voltage DC PIM is designed to interface external high-voltage DC sources with the 3500/15 series mechanical protection system. Installed on the left rear side of the 3500 rack, it safely channels incoming DC power to the internal power modules for system distribution.

        This module works in conjunction with the 3500/15 AC and DC power supplies, which can be installed in one or two slots on the left side of the rack. When two modules are present, one serves as the primary supply while the other functions as a backup, allowing the system to maintain full rack operation without interruption.

        The 115M7750-01 provides flexible power handling by accepting a wide range of DC input voltages and converting them for use by other 3500 modules. Its integration ensures that critical monitoring and protection systems receive stable and reliable power under all operating conditions, supporting both AC and DC supply configurations within the rack.

        The 115M7750-01 Bently Nevada High Voltage DC PIM may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        • Wide Voltage Adaptability: Supports high-voltage DC input from 88 to 140 Vdc, capable of stably coping with voltage fluctuations in industrial power grids.
        • Redundancy Switching Support: Supports hot standby redundancy when used with a dual-power rack. When the main power input fails, the system can seamlessly switch to the backup power supply, ensuring uninterrupted monitoring.
        • High-Efficiency Filtering: Built-in electromagnetic interference (EMI) suppression circuit effectively prevents external power grid noise from entering the 3500 monitoring system, ensuring the accuracy of signal measurement.
        • Hot-Swap Capability: Supports module maintenance and replacement while the system is powered on (subject to safe operating procedures), reducing downtime risks.
        • Wide Temperature Range: Standard operating temperature range is -30°C to +65°C (-22°F to +149°F), suitable for various harsh industrial environments.
        • High Humidity Tolerance: Can withstand up to 95% non-condensing relative humidity at temperatures up to +45°C.
        • Vibration and Shock Resistance: Designed to meet industrial-grade vibration resistance standards (5g peak acceleration), allowing installation in control cabinets adjacent to large rotating machinery.
        • Power Generation: Widely used in steam turbine generator sets, utilizing reliable 110V/125V DC battery banks within the power plant as backup or main power to prevent protection failure due to AC grid flashover.
        • Oil & Gas Extraction and Refining: In compressor stations or offshore platforms in remote areas, connected to DC power distribution systems to provide continuous power for critical axial displacement and vibration monitoring.
        • Critical Protection: Used in automatic interlocking shutdown systems that must comply with API 670 standards, serving as the power backup at the very beginning of the entire protection chain.
        Description
        The Bently Nevada 115M7750-01 High Voltage DC Power Input Module (PIM) provides a reliable interface between external high-voltage DC sources and the 3500/15 series mechanical protection system. Mounted on the left rear side of the 3500 rack, it ensures that incoming DC power is safely and efficiently routed to the internal power modules for processing.

        Designed to handle input voltages from 88 to 140 Vdc, the 115M7750-01 supports a full rack current draw of up to 2.5 A. It operates reliably in harsh industrial environments, with an operating temperature range of -30°C to +65°C and storage capability from -40°C to +85°C, while tolerating up to 95% non-condensing humidity.

        When integrated into a rack with other 3500/15 AC or DC power supplies, the module ensures uninterrupted operation. The system allows for a primary and backup configuration, where the lower-slot supply acts as primary and the upper-slot supply as backup. This hot-swappable design ensures that removing or installing a module does not disrupt system operation as long as a second supply is installed.

        Compared to the Bently Nevada 115M7740-01 Low Voltage DC PIM, the 115M7750-01 supports a higher input voltage range, making it ideal for applications requiring direct high-voltage DC integration. Its robust construction and precise power conditioning make it the preferred choice for high-reliability machinery protection environments.

        By converting incoming high-voltage DC into suitable voltages for use by other 3500 modules, the 115M7750-01 enables consistent performance across the rack. It supports multiple configurations of AC and DC power supplies within a single rack, providing flexibility, redundancy, and reliable power delivery for critical industrial monitoring systems.
