Bently Nevada 3500/15 AC Power Module 133945-01 Genuine

Product Overview

The Bently Nevada 3500/15 (Part Number 133945-01) serves as the primary energy hub for the 3500 Machinery Protection System. This half-high module converts incoming AC line power into the regulated DC voltages required by all monitoring and communication modules within the rack. It maintains system integrity by providing consistent, filtered power to prevent data loss or false trips during industrial voltage fluctuations. We supply this unit as 100% Brand New and Original in factory packaging to ensure immediate deployment readiness.

Part Number Breakdown: 3500/15-AA-BB-CC-DD

The 3500/15 uses a specific ordering matrix to define input types and location. The 133945-01 specifically designates the high-voltage AC variant.

• 01 (High Voltage AC): Supports 100 to 240 V AC inputs.

• 01 (Lower Left Slot): Designates primary power supply position.

• 01 (Standard Application): Standard environmental rating.

• 01 (Agency Approvals): Multi-certification (UL, CSA, ATEX, etc.) included.

Technical Specifications

Engineering Advantages

• High-Availability Redundancy: By installing two 3500/15 modules (one in the upper and one in the lower slot), the system achieves true redundancy. If the primary supply fails, the backup assumes the full load instantly without interrupting machinery protection logic.

• Advanced Power Filtering: The module incorporates heavy-duty line filtering to eliminate electromagnetic interference (EMI) often found in turbine halls and power plants, ensuring clean signals for vibration sensors.

• Hot-Swappable Design: Engineers can replace a failed power supply module while the system remains live (in redundant configurations), eliminating the need for costly production downtime.

• Hazardous Area Compliance: The 133945-01 holds ATEX and IECEx approvals, making it suitable for volatile environments in oil, gas, and chemical processing facilities.

FAQs

Q: Can I mix AC and DC power supplies in the same 3500 rack?

A: Yes. The 3500 system architecture allows for one AC supply and one DC supply to operate simultaneously as a redundant pair. This configuration protects the system against both local grid failures and local battery bank outages.

Q: Does the 133945-01 require a specific slot in the rack?

A: The 3500/15 modules must reside in the dedicated power supply slots on the far left side of the 3500 rack. The 133945-01 is specifically designed for the high-voltage AC input requirements.

Q: How do I verify the health of the 3500/15 module during operation?

A: The front panel features a "Supply OK" LED. Furthermore, the 3500/15 communicates its status to the Rack Interface Module (RIM), allowing operators to monitor power supply health via the System 1 software or a networked display.
