Product Overview

The Bently Nevada 3300/10-01-02-00 is a high-reliability AC power conversion module engineered specifically for the 3300 Series Machinery Protection System. Functioning as the primary energy source for the entire rack, this module occupies the dedicated leftmost slot (Position 1) and transforms standard AC line voltage into the regulated DC voltages required by monitoring cards and field transducers. Its robust, heavy-duty architecture is designed to support up to 12 individual monitors—facilitating up to 36 channels of vibration or speed data—without the need for a secondary or redundant power unit in the same chassis. By utilizing positive-retention connectors rather than mechanical switches for voltage selection, the 3300/10 provides superior stability in high-vibration industrial environments and hazardous area applications.

Industrial Utility and System Applications

Critical Power for Turbomachinery Monitoring

The 3300/10-01-02-00 is the heartbeat of protection systems for steam turbines and high-speed centrifugal compressors. It ensures that even in fully loaded 12-slot racks, every proximity probe and seismic sensor receives clean, regulated power to prevent signal drift or false trips.

Hazardous Environment Reliability

In oil and gas or chemical processing facilities, the use of positive-retention connectors for voltage selection makes this module safer and more reliable than switch-based alternatives. This design minimizes the risk of accidental voltage changes and meets stringent safety requirements for volatile environments.

Global Facility Standardization

Maintenance teams can standardize on a single power module across international sites. Since the 3300/10 can be toggled between 110V and 220V operation with a simple internal cable move, it simplifies spare parts inventory for global spare pools.

Legacy Rack Maintenance

As a core component of the 3300 series, this power supply is vital for extending the operational life of existing machinery protection infrastructure in power generation plants, providing a direct replacement for aging or failed energy units.

FAQ

Q: Can the 3300/10-01-02-00 support a rack with more than 12 monitors?

A: No, the 3300 series rack is designed for a maximum of 12 monitoring slots. The 3300/10 is engineered to provide sufficient amperage to fill all available slots in a standard 19-inch 3300 rack.

Q: Is it possible to change the input voltage from 115V to 220V while the system is running?

A: No. Changing the voltage requires moving an internal connector and replacing the external fuse. The rack must be powered down and disconnected from the mains before performing this adjustment to ensure technician safety.

Q: Does this power supply require a backup unit in the same rack?

A: The heavy-duty design of the 3300/10 is specifically rated to handle the maximum load of a 3300 system on its own. Bently Nevada states that a second power supply in the same chassis is never required.

Q: What happens if the fuse on the 3300/10 blows?

A: A blown fuse will result in a total loss of power to the rack, causing all monitors to enter a "Not OK" state. The fuse is located on the rear of the power supply and must be replaced with the correct rating for your selected input voltage.

Q: Does this module provide power to the transducers (probes) as well?

A: Yes, the 3300/10 supplies the regulated DC voltage that the individual monitor modules then distribute to the field transducers and Proximitor sensors.
