Configured for regulated rack power delivery in the Bently Nevada 3500 Series, the Bently Nevada 3500/15-04-04 114M5330-01 (3500/15-04-04 Power Supply Module) converts 88 to 140 VDC input power for the 3500 rack.

Model Identification

The complete identification supplied is 3500/15-04-04 with part number 114M5330-01. The available data does not define the individual meaning of each "-04" configuration suffix, so no unsupported suffix interpretation is assigned.

The module is specified as a half-height High Voltage DC Power Supply for the 3500 Machinery Protection System. It is intended for installation in the designated power supply position of the rack.

Electrical and Mechanical Data

Power Conversion and Rack Interface

The 3500/15-04-04 receives high-voltage DC input from the external power distribution system and supplies regulated power to the 3500 rack backplane. The module therefore supports the electrical requirements of installed monitoring, relay, communication, and interface hardware.

The supplied data identifies an 88 to 140 VDC input range. No separate numerical output voltage or internal backplane current rating is provided, so those values are not inferred from other 3500/15 configurations.

Machinery Protection Power Architecture

Bently Nevada 3500 systems can use two power supply modules for redundant operation. In the configuration described for this model, the lower supply is the primary source and the upper supply provides the alternate power path.

This arrangement permits replacement of an individual supply while the alternate module remains energized. The supplied information describes this as hot-swappable operation for redundant installations.

The power supply supports the electrical infrastructure used by TSI monitoring hardware, but it does not perform vibration measurement, proximity probe signal conditioning, or rotor-dynamics calculations.

Diagnostic and Protection Characteristics

The supplied information identifies front-panel LED indication for power-supply status and input voltage presence. These indicators provide local electrical status information during commissioning and maintenance.

For Bently Nevada machinery monitoring systems, power integrity is separate from the measurement channel itself. A healthy power supply does not imply that an eddy-current probe circuit, gap voltage, or individual monitoring channel is correctly configured.

Ordering Information

• Rack, external DC wiring, and field installation hardware are not assumed unless separately specified

Field Installation Guidelines

Rack Position

• Install the half-height module in the designated 3500 power supply slot.
• Confirm the module keying and mechanical alignment before insertion.
• Ensure the module is fully seated before applying the DC input.
• Do not apply mechanical force to the front panel or connector during installation.

DC Power Connection

• Verify that the available source is within the specified 88 to 140 VDC range.
• Confirm DC polarity before energizing the rack.
• Use an appropriately rated external protection and distribution circuit.
• Keep high-voltage DC wiring separated from low-level transducer and vibration signal wiring.

Redundant Replacement

• Confirm that the alternate power supply is operating before removing a supply from a redundant rack.
• Follow the site's electrical isolation procedure when working on the DC source.
• Do not assume uninterrupted operation when only one power supply is installed.
• Inspect the connector and mating rack contacts for contamination or mechanical damage before replacement.

EMI and Grounding

• Route power conductors away from sensitive measurement wiring where practical.
• Follow the 3500 rack grounding arrangement and plant bonding requirements.
• Avoid creating unnecessary parallel paths between power wiring and sensor signal shields.

Frequently Asked Questions

• What is the input voltage range of 114M5330-01?

  The supplied technical data specifies 88 to 140 VDC. The external DC distribution source should remain within this range during normal operation.

• Is 3500/15-04-04 a half-height module?

  Yes. The supplied information identifies this configuration as a half-height power supply intended for the designated 3500 rack power supply position.

• Can two power supplies be installed in one 3500 rack?

  Yes. The supplied information specifies redundant operation using two power modules, with the lower module designated as primary and the upper module as backup.

• Is hot-swapping supported?

  The supplied information specifies hot-swap operation in redundant configurations. Removal from a rack operating with only one supply should not be treated as interruption-free.

• What is the output voltage of this power supply?

  No specific numerical output voltage is provided in the supplied data. It should not be inferred from another 3500/15 configuration.

• Does the module process vibration signals?

  No. The module supplies rack power. Vibration measurement, probe conditioning, alarm processing, and related functions are performed by separate 3500 system modules.

• What operating temperature is specified?

  The supplied operating range is -30 deg C to +65 deg C. The stated storage range is -40 deg C to +85 deg C.

• Is the power consumption rating specified?

  No. The supplied data provides the input voltage range but does not state a separate power-consumption figure for 114M5330-01.
