Bently Nevada 3300/10-02-02-00 Power Supply Module

The Bently Nevada 3300/10-02-02-00, also cataloged as the 3300/10 Power Supply Module, operates as a dedicated hardware component for power regulation and distribution within 3300 machinery protection rack frameworks.

Suffix Breakdown & Model Matrix

• Model Series: 3300/10 Power Supply Module

• Option 02: Configured for 190 to 250 VAC input voltage ranges with high-capacity regulation

Hardware Specifications

Gap Voltage Validation and Rotor Dynamics Performance

The power supply module delivers stable, regulated DC operating voltages to backplane rails, ensuring precise excitation currents for eddy-current transducers and maintaining accurate gap voltage validation (-10 VDC targets) across connected monitor cards. It incorporates an integrated line noise filter to suppress high-frequency electrical disturbances from entering the measurement loops, protecting raw dynamic signals and rotor vibration metrics from corruption. In the event of primary power loss, internal fault circuitry triggers the OK relay to drop, preserving fail-safe machine protection monitoring.

Frequently Asked Questions

Q: What is the primary input voltage range for the 3300/10-02-02-00 module?

A: The module accepts an input voltage range of 190 to 250 VAC at 50/60 Hz.

Q: How many monitoring modules can a single power supply unit support within the rack?

A: The module is engineered to provide reliable power for up to 12 monitoring modules and their associated transducers within a standard 3300 rack.

Q: Where is the power supply module positioned within the 3300 rack framework?

A: The unit is designed for installation in Position 1, located at the far left side of the 3300 rack chassis.

Field Installation Guidelines

• Ensure incoming AC power lines are completely de-energized and locked out before sliding the power supply module into Position 1 of the 3300 rack.

• Verify that cabinet operating temperatures remain within the 0 deg C to +65 deg C operational range to prevent internal thermal degradation.

• Connect external alarm annunciation circuits directly to the OK relay terminals to ensure immediate operator notification upon primary power loss or transducer failure.

• Secure the front panel mounting screws firmly to maintain solid backplane pin engagement and proper chassis grounding.
