Component Description
The part number 3500/94 161264-01 refers to a specific module from the Bently Nevada 3500 System, a leading machinery protection and monitoring platform.
3500/94: This designates a Power Supply Module. This module is a critical infrastructure component within the 3500 rack, responsible for converting incoming AC or DC power to the precise DC voltage levels required by all the other monitoring modules (e.g., vibration, speed, temperature) in the rack.
161264-01: This is a specific hardware revision or assembly number for this Power Supply Module.
In summary, the 3500/94 is not a monitoring module itself, but the component that provides stable and reliable power to the entire system. It ensures the continuous and uninterrupted operation of the machinery protection system. Modules like the 3500/94 are typically installed in the left-most slots of the 3500 frame and can be configured in a redundant (primary/backup) configuration for high-availability applications.
Key Parameters
The following table outlines the key parameters for the 3500/94 Power Supply module.
| Parameter | Specification |
|---|---|
| System | Bently Nevada 3500 |
| Primary Function | System Power Conversion & Distribution |
| Input Power | Available in various models for different input voltages (e.g., 100/120/220/240 VAC, 125 VDC). |
| Output Power | Provides regulated +5 VDC, ±15 VDC, and +24 VDC to the rack backplane. |
| Redundancy | Supports redundant (dual) power supply configuration for critical applications. |
| Status Monitoring | Provides status and fault indications via LEDs on the front and to the system software. |
| Mounting | Slides into dedicated power supply slots on the left side of a 3500 rack. |
| Dimensions (H x W x D) | Approx. 193 mm x 110 mm x 200 mm (7.6 in x 4.33 in x 7.87 in) Note: Typically twice the width of a standard monitor module. |
| Weight | Approx. 1.8 kg (4.0 lbs) |
Application Scenarios
The 3500/94 Power Supply is a foundational element in every 3500 system installation. Its application is universal, but its criticality is highest in the following scenarios:
Critical Machine Protection Systems:
Application: Gas & Steam Turbines, Centrifugal Compressors.
Function: Provides clean, stable power to all monitoring and relay modules. In these applications, it is almost always used in a redundant pair to ensure that a single power supply failure does not compromise the entire machinery protection system, which could lead to a catastrophic failure.
Power Generation Plants:
Application: All critical auxiliaries in a power plant (e.g., boiler feed pumps, forced draft fans, generators).
Function: Ensures the continuous operation of the monitoring system, which is essential for grid reliability and preventing forced outages. The power supply must handle potential voltage fluctuations common in industrial power environments.
Offshore Platforms and Remote Installations:
Application: Oil and gas production platforms, compressor stations.
Function: In these harsh and remote environments, reliability is paramount. The 3500/94 is designed to provide dependable power, and its redundancy feature is crucial for maintaining safety and production where maintenance access may be delayed.
Any Bently Nevada 3500 Rack:
Application: Any installation using the 3500 monitoring system.
Function: It is the mandatory power source for the rack. Without it, or in the event of its failure without a backup, the entire monitoring and protection system for that rack becomes inoperative.
