- Product Introduction & Supply Chain Strategy
The Bently Nevada 3500/15 AC Power Supply Module converts plant utility power into regulated internal voltages required by all processing, monitoring, and relay cards within a 3500 machinery protection rack. It can operate as a single supply or in pairs to deliver full power redundancy with seamless automated load-sharing and failover.
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability. Refurbished power supplies carry severe hidden risks of degraded electrolytic capacitors, dried thermal paste, or transformer coil fatigue from continuous high-temperature panel operation. A power supply crash on a non-redundant rack drops protective monitoring on critical turbines and compressors instantly. Securing this module as New Surplus maintains full operational uptime, lowers total cost of ownership (TCO), and insulates your facility from emergency factory lead times.

- Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
High-Voltage Electrical Hazard
Disconnect and isolate primary AC supply lines before working near input terminals to prevent electrical shock.
- Wear a grounded ESD wristband before handling the module.
- Verify input AC line voltage is within the nominal 85 to 264 V AC operating window.
- Document current wiring connections to the power supply PIM (Power Input Module) on the rear of the rack.
Stage 2: Removal
- Turn off the AC circuit breaker supplying the specific 3500/15 power supply card.
- Loosen the upper and lower captive thumbscrews on the front panel using a flathead screwdriver.
- Pull the extraction handle straight outward to disengage internal backplane connectors safely without damaging connector pins.
Stage 3: Installation (Clone & Seat)
- Slide the new 3500/15 power supply module into the designated upper or lower left power slot along the guide rails.
- Push firmly until the module seats into the backplane power bus.
- Hand-tighten the captive front panel screws to secure the unit against cabinet vibration.
Stage 4: Power-On & Testing
- Re-energize the incoming AC supply breaker.
- Observe the front panel LEDs: verify the green SUPPLY OK light illuminates steadily and the FAULT LED remains off.
- Verify in the 3500 Configuration Software that backplane bus voltages fall within specified limits and no system supply alarms are flagged.
- Firmware/Software Versions & Upgrade Notes
- Hardware Architecture: The 3500/15 Power Supply is a purely electromechanical and power-conversion card; it contains no microprocessor firmware, flash memory, or configurable DIP switches.
- Compatibility Notice: Ensure you match input voltage requirements (High Voltage AC 85–264 V AC vs Low Voltage DC 18–36 V DC variants) when ordering replacement units. High Voltage AC modules are not interchangeable with Low Voltage DC PIMs.
- Redundancy Rule: When running a dual-redundant power setup, both power supplies should ideally be of the same power rating (e.g., pairing two High-Power 175 W units) to guarantee full load coverage in the event of a single supply trip.
- Frequently Asked Questions (FAQ)
Q: Are these units really brand new, or are they refurbished/repaired cards? A: This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules feature zero connector pin wear, pristine internal board components, zero thermal discoloration, and original packaging opened only for mandatory QC testing.
Q: Why is New Surplus priced higher than refurbished power supplies on the market? A: Refurbished power supplies often contain aged electrolytic capacitors near the end of their operational lifespan. Saving $200 on a used power module can cause an unexpected power loss across an entire 15-channel protection system. Our pricing reflects genuine, factory-fresh inventory that delivers a 10–15 year operational lifespan and zero failure risk out of the box.
Q: Can I replace a failed 3500/15 power supply while the rest of the 3500 rack is running? A: Yes. If your 3500 rack is equipped with dual redundant power supplies, you can safely hot-swap a failed power supply module while the second supply powers the system backplane without interrupting active protection channels.
Q: What is the difference between the front power supply module and the rear PIM (Power Input Module)? A: The front 3500/15 card houses the primary AC-to-DC conversion circuitry, transformers, and regulation components. The rear Power Input Module (PIM) serves as the physical interface for incoming AC field wiring and fuse protection.
Q: What warranty coverage applies to this module? A: Every 3500/15 New Surplus power supply module comes backed by a comprehensive 1-year replacement warranty, fully verified through physical inspection, high-potential voltage testing, and ESD-safe packaging protocols.
