Bently Nevada 3500/15-05-05-CN Power Supply Module – Stable Rack Power for the 3500 Machinery Protection System

The 3500/15-05-05-CN is a dedicated power supply module for the Bently Nevada 3500 rack, designed to deliver clean, stable power to every monitor, relay, and communication card in the system. It supports redundant operation (primary + backup) to keep your protection and condition monitoring online even if one supply is removed or fails. From my experience, this module is chosen when plants want a no-drama, “fit-and-forget” supply with straightforward installation and predictable uptime.

• Rack-wide regulated power – Feeds the entire 3500 backplane so all monitoring and relays receive stable power.

• Redundancy support – Two supplies can be installed; one thing I appreciate is you can hot-swap a failed unit while the rack stays energized by the other.

• Status indication – Front-panel LEDs provide quick health checks during commissioning or troubleshooting.

• AC input variant – The -05-05-CN configuration is commonly associated with AC input versions used in general-purpose plant power systems.

• Drop-in fit for 3500 racks – Installs in the designated power slot(s); no special tools or adapters in most cases.

• Designed for 24/7 service – Built for continuous operation in industrial cabinets near turbines, compressors, and other rotating assets.

The 3500/15 series is used anywhere a 3500 rack protects and monitors critical rotating equipment. You might notice it most in:

• Gas and steam turbines in power generation (base-load and peaking plants)

• Compressors and pumps in oil & gas, petrochemical, and refinery units

• Large fans, blowers, and motors in steel, cement, paper, and mining operations

• Critical utilities skids (boilers, chillers) where high availability monitoring is required

• High availability – Redundant architecture reduces unplanned outages during maintenance or failure events.

• Lifecycle continuity – Compatible with the 3500 ecosystem; spares strategy is straightforward for multi-site operators.

• Lower total cost – Fewer nuisance trips and faster swaps translate into reduced downtime costs in many cases.

• Clear status cues – LED indicators shorten troubleshooting time for electricians and control techs.

• Proven in harsh environments – The 3500 platform has a long track record in continuous-duty services.

• Panel/cabinet – Mount the 3500 rack in a clean, ventilated cabinet. Maintain airflow around the rack; avoid heat sources.

• Power wiring – Feed the supply from a stable AC source; using a UPS or conditioned mains is advisable for critical assets. Proper grounding is essential.

• Redundancy – For high availability, install two 3500/15 supplies. You can replace one while the other maintains rack power.

• Safety – De-energize the feed if you do not have a redundant unit online. Observe local electrical standards and lockout/tagout practices.

• Routine care – Periodically check terminals for tightness, clean dust from vents, verify LED status, and record supply health during PM rounds.

• Firmware/software – The power module itself doesn’t need firmware updates, but it’s good practice to keep the overall 3500 system configuration backed up.

• Manufactured under ISO 9001 quality systems (platform level)

• CE and UL/CSA compliance typically applicable to the 3500 platform

• RoHS alignment on most current production units

• Standard manufacturer warranty is typically 1 year; extended coverage may be available

Note: The “-05-05-CN” suffix appears to designate a specific AC input configuration and regional packaging/document set. If your site standard requires a DC-input power module, or if you need exact voltage/frequency details, I can match the supply code to your rack and share the verified datasheet before you order.
