Description
Product Introduction & Engineering Value
A machinery protection system is only as dependable as its power source. Even when every monitoring module is operating correctly, an unstable or failed power supply can render the entire rack unavailable. The Bently Nevada 170115-01 is designed to provide regulated operating power for the 3500 Machinery Protection System, supporting continuous monitoring of critical rotating equipment.
In facilities where compressor trains, steam turbines, or generators operate around the clock, the module is commonly installed in redundant power configurations to improve system availability during maintenance or an unexpected power supply failure.
Technical Specifications
Manufacturer: Bently Nevada
Part Number: 170115-01
Series: 3500 Machinery Protection System
Product Type: Rack Power Supply Module
Installation: Dedicated power supply slot within the 3500 rack
Power Configuration: Supports redundant power supply architecture
Maintenance: Hot-swappable in redundant configurations
Cooling Method: Passive convection cooling
Application: Continuous machinery protection and condition monitoring
Compatible Equipment: Bently Nevada 3500 monitoring racks
Typical Industries: Power generation, refining, petrochemical processing, LNG, pipeline compression, mining operations.
Note: Input voltage range and matching Power Input Module (PIM) depend on the specific 3500 power supply configuration. Always verify the complete assembly number before ordering a replacement.
Field Application & The “Trench” Experience
During a scheduled shutdown at a gas compression station, technicians replaced several aging vibration monitors in a 3500 rack. After startup, the rack repeatedly reported intermittent power diagnostics despite stable incoming station power.
The maintenance team isolated the issue to an aging 170115-01 power supply module. After replacing the unit and verifying redundant switchover between both rack power supplies, all monitoring channels returned to normal operation. Because the replacement matched the original hardware revision, commissioning required only a functional verification instead of a complete rack reconfiguration.
Typical applications include:
- Steam turbine machinery protection racks
- LNG refrigeration compressor monitoring systems
- Boiler feed pump protection systems in thermal power plants

Transparency SOP: QA & Testing
Every New Surplus or professionally refurbished 170115-01 undergoes documented inspection before shipment.
- Confirm manufacturer identification, serial number, and hardware revision.
- Inspect housing, connectors, and PCB assemblies for physical damage.
- Verify terminal integrity and connector retention.
- Perform electrical functional testing using a compatible 3500 rack when available.
- Confirm stable output under simulated operating conditions.
- Package the module using anti-static materials and industrial-grade impact protection.
The Veteran’s Tech Trap Guide
⚠️ Don’t confuse the Power Supply with the Power Input Module (PIM).
The 170115-01 power supply works together with a matching Power Input Module. These are separate assemblies and are not interchangeable. Ordering only one component may not resolve a rack power issue.
⚠️ Inspect the backup supply as well.
Many facilities replace only the failed power supply while leaving the second redundant unit untouched. If both modules have operated continuously for many years, replacing only one may simply postpone the next outage.
PRO TIP:
Before replacing the module, record the rack diagnostic log. Power-related alarms can sometimes originate from an external DC source or degraded input wiring rather than the power supply itself.
Dynamic FAQ
Q1. What is the function of the 170115-01?
The 170115-01 provides regulated operating power for the Bently Nevada 3500 Machinery Protection System, ensuring continuous operation of installed monitoring modules.
Q2. Can the module be replaced while the rack is operating?
In racks configured with redundant power supplies, replacement may be possible without shutting down the entire system, provided plant procedures and safety requirements are followed.
Q3. Is the 170115-01 compatible with every 3500 rack?
It is designed for the 3500 Machinery Protection System, but compatibility depends on the associated Power Input Module, rack configuration, and input voltage. Always verify the complete part number before installation.
Q4. What typically causes power supply replacement?
Common reasons include output instability, aging electrolytic capacitors, failure to initialize the rack, intermittent power diagnostics, or preventive replacement during major plant outages.
Q5. What does “New Surplus” mean?
A New Surplus module is an unused OEM component obtained from excess inventory or canceled projects. Although it has not been installed in service, it is inspected and verified before shipment.
Q6. Is warranty coverage available?
Yes. Warranty availability depends on inventory condition and supplier policy. Both New Surplus and professionally refurbished modules are generally supplied with documented inspection records and functional testing prior to shipment.
