Bently Nevada 125840-01 High Voltage AC Power Input Module (PIM)

The Bently Nevada 125840-01 High Voltage AC Power Input Module serves as the high-integrity electrical boundary for the 3500 series machinery protection rack.Positioned in the dedicated power section on the far left side of the backplane, it channels line voltage into the paired 3500/15 step-down power conversion hardware.

The module is explicitly designed to handle heavy industrial line environments.It incorporates premium line filtering and dedicated surge restriction configurations.When integrated into a dual-supply system topology, the 125840-01 operates in full N+1 hot-standby configuration.If a primary phase anomaly occurs, the sister power module balances the system load automatically.This prevents any downtime in continuous shaft vibration, proximity monitoring, or rotational analytics.

• System Component Pairing: Bently Nevada 3500/15 Power Supply Series.

• Nominal Input Voltage Envelope: 175 to 264 Vac RMS (High Voltage AC standard).

• Input Frequency Bandwidth: 47 to 63 Hz line frequency.

• Onboard Safety Safeguards: Built-in overvoltage overcurrent fuse paths; designed to sacrifice the input line block before damage hits inner components.

• Physical Profile: Half-height rear-facing input chassis format.

• Component Net Weight: Approximately 0.34 kg (0.75 lbs).

• Environmental Range (Operational): -30°C to +65°C (-22°F to +150°F) continuous.

• Climatic Tolerance: 95% non-condensing relative humidity maximum limit.

• Hazardous Area Standards: Compliance via ATEX / IECEx Zone 2 approvals and Class I, Division 2, Groups A, B, C, D environments.

• Fault-Isolated System Redundancy: Supports dual-supply active pairing, meaning the component can be extracted or replaced while the tracking monitors run hot.

• Integrated Line Surge Protection: Houses dedicated safety fusing that instantly opens during voltage spikes, preventing transient destruction of processing assets.

• Optimized Form Allocation: The specialized half-height design allows separate power paths to occupy a single slot profile, preserving rack space for core monitors.

• Low Noise Grounding Matrix: Implements clean-grounding construction to lower electrical noise, keeping machine vibration metrics accurate.

The 125840-01 PIM ensures uninterrupted power delivery to critical safety components across continuous-operation process facilities:

• Hydrocarbon Processing: Midstream gas plants, offshore oil platforms, and safety-critical refinery air compressors.

• Power Utility Infrastructure: Utility baseload steam turbines, critical gas turbine enclosures, and generator monitoring frameworks.

• Heavy Raw Material Refining: Blast furnace air handlers, process expander sets, and massive industrial water pumps.

Q1: Can the 125840-01 module accept Low Voltage AC or DC inputs?

A1: No. The 125840-01 is explicitly a High Voltage AC module calibrated for line inputs ranging from 175 to 264 Vac RMS.Low Voltage AC lines require the 125840-02 module, while DC sources utilize distinct DC PIM options.

Q2: Is the replacement fuse on the 125840-01 hot-swappable in hazardous areas?

A2: No. While the power supply module itself can be hot-swapped safely if a second supply powers the rack, changing a blown fuse requires isolating the source power line to comply with standard field location safety constraints.

Q3: Where exactly is this module mounted within the Bently Nevada 3500 system enclosure?

A3: The 125840-01 is an input module that installs into the backplane from the rear of the rack.It sits directly behind the corresponding main 3500/15 power supply card located in the far-left slot.
