Bently Nevada 3500/15 114M5330-01 | Low Voltage DC Supply

• Brand: Bently Nevada
• Full Model Number: 3500/15 114M5330-01
• Lifecycle Status: Active / Current 3500/15 DC configuration
• Core Function: Low Voltage DC Power Supply for 3500 Series racks
• Top 3 Technical Specs: 20–30 VDC input; 24 VDC ±1% backplane output; maximum input current 10 A at 20 VDC
• Stock & Condition: New Surplus / Tested Refurbished; Physical stock confirmation required; Emergency dispatch subject to order cutoff

The 114M5330-01 is the Bently Nevada 3500/15 Low Voltage DC Power Supply. Current 3500/15 documentation lists it separately from the older 133292-01 Legacy Low Voltage DC Power Supply, while specifying the LVDC supply class at 20–30 VDC. Published technical data also specifies 24 VDC ±1% distributed through the backplane and a maximum input current of 10 A at 20 VDC.

Module 3: Obsolescence & Supply Chain Deep Dive

A failed 114M5330-01 can remove rack power from an operating Bently Nevada 3500 machinery-protection system, making the exact electrical configuration more important than the generic “3500/15” model designation. This unit is the current Low Voltage DC Power Supply listed for the 3500/15, with a 20–30 VDC input and 24 VDC ±1% output through the rack backplane. The 3500/15 accepts one or two power supplies, with the lower unit serving as primary and the upper unit as backup when two are installed.

From a TCO perspective, replacing the failed supply preserves the existing rack, monitor modules, field wiring, and installed protection architecture. A dual-supply arrangement also allows replacement work without rack interruption when the second supply is functioning, according to the published 3500/15 specification. The major procurement risk is confusing 114M5330-01 with the older 133292-01 legacy LVDC supply: Bently Nevada’s spare-parts documentation lists them separately, and current documentation warns that newer DC supplies and legacy DC supplies/PIMs are not interchangeable.

Module 4: Compatibility & Replacement Matrix

Field Traps — Watch Out

• Current versus legacy supply: Do not substitute 133292-01 simply because both are 3500/15 Low Voltage DC supplies. The official spare-parts list distinguishes 133292-01 Legacy Low Voltage DC Power Supply from 114M5330-01 Low Voltage DC Power Supply.
• PIM compatibility: The current 3500/15 documentation separately lists 114M5335-01 as the Low Voltage DC PIM and 133300-01 as the Legacy Low Voltage DC PIM. Verify the power-supply/PIM generation as a matched configuration before PO approval.

Module 5: Quality Assurance & Testing SOP

The 114M5330-01 sits directly in the rack power path, so pre-shipment QA should include controlled DC testing under representative load.

• Incoming traceability: Record Bently Nevada identification, complete 114M5330-01 part number, serial number, revision, and date-code information.
• OEM anti-counterfeit visual inspection: Inspect labels, PCB markings, connectors, enclosure, components, solder joints, and evidence of unauthorized repair.
• Mechanical inspection: Check rack guides, retention hardware, connector alignment, housing, and rear PIM interface.
• Power-on self-test (POST): Install the supply in an approved 3500/15 test rack and verify normal startup and Supply OK indication.
• Input-voltage test: Apply controlled DC input across the specified 20–30 VDC range.
• Output verification: Measure the rack backplane output and verify the specified 24 VDC ±1% condition.
• Load testing: Apply representative rack loads and monitor output voltage, input current, temperature rise, and stability.
• Protection testing: Verify applicable input and output protection behavior using an approved laboratory procedure.
• PIM interface test: Confirm correct electrical interaction with the appropriate current-generation LVDC PIM.
• Rack integration test: Power a representative 3500 rack and verify correct operation of connected modules.
• Redundancy test: Where a second supply is available, verify primary/backup operation.
• Hot-swap verification: With a functioning redundant supply installed, perform controlled insertion/removal testing in accordance with the applicable 3500/15 procedure.
• Extended operation: Run representative load continuously while monitoring output stability, current, temperature, and status indication.
• Final QC release: Record input voltage, output voltage, load-test results, Supply OK status, serial number, inspection date, and technician approval.

Module 6: Procurement & Lifecycle FAQ

1. Is the Bently Nevada 3500/15 114M5330-01 genuinely in stock, and what is the cutoff for emergency shipping?

Current supplier information is mixed. One current listing reports an estimated 8–10 week lead time, while another lists the part as an established 3500/15 LVDC power-supply model. For an emergency order, physical warehouse quantity, exact part number, condition, and dispatch cutoff should be confirmed before PO release.

2. How do you verify the condition and authenticity of this surplus power supply?

Verify the complete 114M5330-01 identification, revision, serial information, PCB condition, connectors, enclosure, and PIM interface. Controlled testing should then verify 20–30 VDC input, approximately 24 VDC ±1% backplane output, representative load performance, and Supply OK status.

3. Are there any firmware compatibility issues I should warn my engineers about before issuing the PO?

There is no application firmware requirement for the power-supply module. The critical issue is electrical generation compatibility. Engineers should verify that the rack is configured for the current LVDC supply and corresponding 114M5335-01 PIM, rather than the older 133292-01 / 133300-01 legacy combination.

4. Can the 114M5330-01 replace the installed 3500/15 power supply without hardware modification?

For an existing 114M5330-01 installation, the replacement is normally a direct hardware change with no cabinet modification. Confirm the rack position, LVDC PIM generation, input voltage, connector arrangement, and redundant-supply configuration before installation.

5. What warranty and return terms should procurement require?

The PO should specify Bently Nevada 3500/15 114M5330-01, exact condition, revision, compatible PIM arrangement, electrical test status, warranty period, and return procedure. Warranty coverage should address DOA and verified power-supply failure while excluding damage caused by incorrect DC input, polarity errors, rack faults, overload, wiring mistakes, or unauthorized modification.
