Bently Nevada 3300/12 Power Supply Module — Dedicated Power Infrastructure | 3300 Series Vibration Monitoring Platform
Engineering Background
The Bently Nevada 3300 Series is one of the most widely deployed continuous vibration monitoring platforms in rotating machinery protection worldwide. Installed across gas turbines, steam turbines, compressors, pumps, and generators in oil & gas, power generation, and petrochemical industries, the 3300 system architecture relies on a stable, conditioned power supply to maintain uninterrupted signal integrity across all monitoring channels. The 3300/12 Power Supply Module is the dedicated power infrastructure component engineered specifically for this platform.
Product Positioning
The 3300/12 is not a generic industrial power supply — it is a purpose-built module designed to deliver regulated, noise-filtered DC power to the 3300 Series monitor rack. For procurement engineers maintaining or expanding existing 3300 Series installations, the 3300/12 is a direct OEM-equivalent replacement that ensures system compatibility, regulatory compliance, and long-term operational continuity without requiring rack reconfiguration or firmware updates.

System Architecture & Signal Flow
Within the 3300 Series rack, the 3300/12 Power Supply Module occupies the dedicated power slot and distributes conditioned ±24 VDC to all installed monitor modules via the rack backplane. The power supply accepts facility AC or DC input, performs active power factor correction and galvanic isolation, and delivers regulated output with transient suppression. In redundant configurations, two 3300/12 modules operate in parallel with automatic load sharing and failover — if one module fails, the second assumes full load without interruption to monitoring channels or alarm outputs.
This architecture is critical for SIL 2/3 protection loops where power supply failure must not cause a spurious trip or loss of protection function.
Sourcing & Quality Verification
Konmask.com sources the Bently Nevada 3300/12 through established industrial automation supply channels with documented traceability. Each unit offered is:
- Inspected for physical integrity, label authenticity, and connector condition prior to listing
- Stored in ESD-safe, climate-controlled warehouse conditions
- Available with original OEM packaging where stock permits
- Traceable to supplier documentation upon request for regulated-industry procurement
We do not list units with missing labels, damaged connectors, or unverifiable provenance. If you require factory calibration certificates or third-party inspection reports, contact our technical team before placing an order.
Procurement Process
- Step 1 — Confirm Part Number: Verify your existing rack configuration requires the 3300/12 (not 3300/12-01 or other sub-revisions). Check the module label or your system BOM.
- Step 2 — Request Quote: Contact support@konmask.com with quantity, required delivery timeline, and any documentation requirements (CoC, test reports).
- Step 3 — Order Confirmation: We confirm stock availability, lead time, and shipping terms (EXW Xiamen / CIF destination available).
- Step 4 — Shipment & Documentation: Units ship with commercial invoice, packing list, and available traceability documents. Export compliance handled per destination country requirements.
- Step 5 — Incoming Inspection: We recommend incoming inspection per your facility’s spare parts acceptance procedure before installation.
Technical FAQ
Q: Is the 3300/12 compatible with all 3300 Series monitor modules?
A: Yes. The 3300/12 is the standard power supply for the 3300 Series rack and is compatible with all standard 3300 Series monitor modules including vibration, position, speed, and temperature monitors.
Q: Can I use the 3300/12 with a DC power source?
A: Yes. The wide-range input accepts 100–370 VDC in addition to 85–264 VAC, making it suitable for battery-backed DC bus installations common in offshore and remote facilities.
Q: What happens if the power supply fails during operation?
A: In a single-supply configuration, loss of the 3300/12 will de-energize the rack and all connected monitors. In a redundant dual-supply configuration, the second module assumes full load automatically. Bently Nevada recommends redundant power supply configuration for all safety-critical applications.
Q: Do you provide a warranty?
A: Konmask.com provides a limited warranty on all supplied modules. Contact support@konmask.com for warranty terms applicable to your order.
Q: Can you supply documentation for regulated-industry procurement?
A: Yes. Certificate of Conformance, supplier traceability documentation, and inspection records are available upon request. Specify your documentation requirements at the time of inquiry.
Q: What is the lead time?
A: Lead time depends on current stock levels. In-stock units typically ship within 3–5 business days. Contact us for real-time availability.
