This rack-mounted unit provides stable, regulated DC power to all installed monitoring modules, supporting critical machinery protection functions including vibration, thrust, eccentricity, expansion, tachometer, and temperature monitoring.

Features

• Provides regulated power distribution across the 3300 series rack backplane.
• Integrated OK relay for system-wide power status monitoring and fault indication.
• Designed for high-voltage DC input environments.
• Standardized rack-mount form factor for seamless integration into existing 3300 system architectures.

Applications

This power supply module is essential for the operation of Bently Nevada 3300 monitoring systems used in industrial rotating machinery protection, including gas and steam turbines, compressors, pumps, and motors.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is powered down before inserting or removing the module to prevent electrical damage.
• Slide the module into the designated rack slot, ensuring the backplane connector is properly aligned.
• Secure the module using the front-panel captive screws to ensure proper grounding and mechanical stability.
• Verify that the input voltage matches the 3300/14-01-20-00 configuration requirements before applying power.
• Maintain adequate ventilation around the rack to ensure operating temperatures remain within the 0 to 60 degC range.

FAQ

What is the function of the OK relay on this module?

The OK relay provides a contact closure to indicate the health and status of the power supply. If the module fails to provide the required regulated voltage to the rack, the relay will change state, allowing the system to trigger an alarm or alert the control system.

Is this module compatible with all 3300 series racks?

Yes, the 3300/14 is designed specifically for the 3300 series rack architecture. Ensure your rack backplane is configured to support the power requirements of your specific module load.
