Bently Nevada 3500/15-05-05-00 – AC/DC Power Supply Module | 3500 Series Machinery Protection Platform
Engineering Background
The Bently Nevada 3500 Series is the industry-standard platform for continuous online machinery protection in rotating equipment applications — turbines, compressors, pumps, and generators across oil & gas, power generation, and petrochemical industries. Reliable, conditioned power delivery is the foundation of every 3500 rack installation, and the 3500/15-05-05-00 Power Supply Module is purpose-engineered to meet that demand.
Product Positioning
The 3500/15-05-05-00 is a dual-input (AC and DC) power supply module designed for installation in the 3500 Series rack. It provides regulated, isolated power to all monitoring and I/O modules within the rack, ensuring uninterrupted protection system operation even during primary power fluctuations. Procurement engineers specify this module as the primary or redundant power source in safety-critical monitoring architectures.

Proven Application Environments
- Oil & Gas: Upstream compressor trains, LNG turbine protection racks
- Power Generation: Steam and gas turbine monitoring systems
- Petrochemical: Reactor and pump protection panels
- Marine & Offshore: Platform machinery protection with DC backup power
- Pulp & Paper / Mining: High-vibration environments requiring stable power conditioning
Engineering Advantages
- Universal AC/DC Input: Single module accepts both AC mains and DC battery backup — eliminates need for separate supply modules in redundant architectures
- Galvanic Isolation: Protects sensitive monitoring electronics from ground loops and common-mode noise on plant power networks
- Hot-Swap Capable: Designed for live rack insertion/removal without disrupting adjacent monitoring channels
- Wide Temperature Range: Qualified for harsh industrial environments from arctic to tropical
- Redundancy-Ready: Pair two 3500/15-05-05-00 modules for N+1 power redundancy — critical for SIL-rated protection loops
System Architecture & Signal Flow
In a standard 3500 rack configuration, the 3500/15-05-05-00 occupies the power supply slot (leftmost position). AC or DC plant power enters via the rear terminal block. The module converts and regulates input power to the internal rack bus voltages (+5 VDC, ±15 VDC), which are distributed to all installed monitor modules (vibration, temperature, speed, position). A second 3500/15-05-05-00 can be installed in the redundant power slot; the rack automatically switches to the backup supply upon primary failure with no interruption to protection outputs.

Technical FAQ
Q: Can the 3500/15-05-05-00 operate on DC power only?
A: Yes. The module accepts 18–72 VDC input independently, making it suitable for battery-backed or UPS-fed installations without AC mains.
Q: Is this module compatible with all 3500 Series racks?
A: Yes. The 3500/15-05-05-00 is the standard power supply for all 3500 rack configurations including 3500/05, 3500/20, and expanded racks.
Q: Can two units be installed for redundancy?
A: Yes. The 3500 rack supports dual power supply slots. Both modules operate in load-sharing mode; upon failure of one, the other assumes full load automatically.
Q: What documentation is available?
A: Bently Nevada product manual (part number 129768-01), wiring diagrams, and Konmask pre-shipment inspection report available upon request.
Q: What is the typical lead time for bulk orders?
A: 5–15 business days depending on quantity and destination. Express air freight available for urgent requirements.
