BENTLY 3500/15 127610-01

Description

Product Overview

The BENTLY 3500/15 127610-01 is a foundational power supply module for the Bently Nevada 3500 Machinery Protection System (MPS). This module serves as the primary source of conditioned and regulated power for all monitoring and protection modules within a 3500 rack, such as vibration monitors, proximity probes, and communication gateways. The reliable operation of the entire protection system depends on the stable output of the BENTLY 3500/15.

Key Product Parameters

• Product Type: System Power Supply Module

• Compatible System: Bently Nevada 3500 Series Rack

• Part Number: 3500/15, with 127610-01 as a specific hardware revision or orderable code.

• Input Voltage: Typically accepts a wide-range AC or DC input (e.g., 85-265 VAC, 47-440 Hz, or 90-140 VDC).

• Outputs: Provides multiple isolated and regulated DC voltage outputs to power the rack’s backplane and modules (e.g., +5 VDC, ±12 VDC, ±15 VDC).

• Redundancy: Supports 1:1 redundant configuration. Two 3500/15 modules can be installed in a rack, with automatic switchover if the primary fails.

• Mounting: Occupies one slot in the 3500 rack, typically in slots 1 and/or 2 (for redundant pairs).

• Diagnostics: Features front-panel LED status indicators for power on, fault, and redundant operation.

• Cooling: May include an internal fan for heat dissipation.

Advantages and Core Features

The primary advantage of the BENTLY 3500/15 127610-01 is its specialized design for mission-critical machinery protection. It provides exceptionally clean and stable power, which is crucial for the accurate measurement of sensitive vibration and position signals. Its integrated redundancy support ensures continuous system operation without interruption, a non-negotiable requirement for protecting expensive turbomachinery. The module is built to withstand the electrical noise and environmental conditions found in power plants and industrial facilities. The reliability of the 3500/15 is a cornerstone of the 3500 system’s trusted performance.

Application Scenarios

This power supply is used in any application where a Bently Nevada 3500 system monitors critical rotating equipment:

• Power Generation: Providing power to vibration and speed monitoring systems for gas turbines, steam turbines, generators, and large pumps/fans in plants.

• Oil & Gas: Powering protection racks on centrifugal compressors, gas turbines, and pumps in upstream, midstream, and downstream facilities.

• Petrochemical & Chemical: Supporting monitoring systems for critical compressors and turbines in ethylene, ammonia, and other process plants.

• Marine: Used in monitoring systems for propulsion turbines and generators on ships.

• Pulp & Paper: Protecting large turbines and fans in mill operations.

Comparison with Competing Products

Competing products include system power supplies from other machinery protection system vendors like Emerson (CSI 6500 power supply) or Schenck (Vibroguard power supply). The BENTLY 3500/15 is distinguished by its complete integration and validation within the 3500 platform. Its electrical characteristics are precisely matched to the needs of Bently’s monitor modules, and its communication with the rack’s framework module for diagnostics is seamless. Compared to generic industrial power supplies, the 3500/15 offers guaranteed compatibility, certified performance for safety systems, and simplified engineering within the proven 3500 architecture.

Selection Guide and Important Notes

The BENTLY 3500/15 127610-01 is a required component for every 3500 rack. For critical applications, a redundant pair is the standard configuration.

Important Precautions:

• Redundancy is Standard: For any machinery protection application, a redundant pair of 3500/15 modules should always be specified and installed in slots 1 and 2.

• Input Power Source: The power source should be clean and highly reliable, often sourced from an uninterruptible power supply (UPS) system dedicated to the protection equipment.

• Firmware Compatibility: Ensure the power supply module’s firmware revision is compatible with the other modules (especially the 3500/92 Communication Gateway or 3500/22 Transient Data Interface) in the rack.

• Thermal Management: Ensure the rack has adequate ventilation. Do not block the air intake or exhaust vents of the 3500/15 module.

• Professional Installation: Installation and configuration should be performed by personnel trained on the 3500 system, as improper setup can affect the entire rack’s operation.
