The Bently Nevada 3300/12-01-20-00 is a dedicated rack-mounted power supply module engineered for the 3300 Series monitoring system. It serves as the primary source of regulated DC power for all installed monitors, including those managing vibration, thrust, eccentricity, expansion, tachometer, and temperature parameters. By ensuring a steady and clean power distribution, this module maintains the integrity and continuous operation of critical machinery protection systems.

Features

• Provides stable, regulated DC output to support full rack capacity.
• Integrated status monitoring with dedicated OK relay for system health diagnostics.
• Designed specifically for the 3300 Series rack architecture.
• High-voltage input configuration (220/240 VAC) for industrial power environments.
• Robust construction suitable for continuous, high-availability monitoring applications.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is completely de-energized before inserting or removing the power supply module.
• Verify that the input power source matches the 220/240 VAC requirements specified for this unit.
• The module must be fully seated in the rack to ensure proper connection with the backplane.
• Maintain adequate airflow around the 3300 rack to prevent exceeding the 60 degC operating limit.
• Follow standard ESD precautions when handling the module to protect internal circuitry.

FAQ
