The Bently Nevada 3500/15 114M5329-01, also cataloged as the 3500/15 High Voltage DC Power Supply, provides regulated DC power to the internal modules of a Bently Nevada 3500 Series rack.

Model and Configuration

The supplied identification specifies 3500/15 as the base model and 114M5329-01 as the complete part number. No further suffix decoding is assumed because the supplied data does not define an individual meaning for "-01".

The 3500/15 uses a half-height form factor and occupies a designated power supply position on the left side of the 3500 rack. A single supply is specified as capable of supporting a fully loaded rack. Two supplies can be installed for redundant power operation.

Hardware Specifications

DC Power and Rack Loading

The 3500/15 accepts an 88 to 140 VDC input and converts the incoming DC bus voltage into regulated power for the 3500 rack. The stated output capacity is load dependent and is given as 150 to 300 W.

The power supply is installed independently of the monitoring channels. Its electrical output supports rack electronics rather than directly conditioning proximity probe or other field sensor signals.

Redundant Power Architecture

The supplied configuration permits two 3500/15 modules to operate as a redundant pair. The lower module is identified as the primary source and the upper module as the backup source.

With two supplies installed, maintenance of an individual power supply can be performed while the alternate supply remains in service. The supplied data identifies the module as hot-swappable under this redundant operating condition.

Ordering Information

• 1 x Bently Nevada 3500/15 114M5329-01 High Voltage DC Power Supply Module
• 1 x Half-height power supply module assembly
• 1 x Factory-installed module hardware
• 1 x Additional redundant power supply only if separately specified
• Rack, external DC wiring, connectors, and installation accessories are not assumed unless specifically listed

Installation and Wiring

Rack Installation

• Install the module only in the designated 3500 power supply position.
• Verify the rack slot and module orientation before insertion.
• Ensure the module is mechanically seated before energizing the rack.
• For redundant operation, verify that the second power supply is installed and operational before removing an active module.

DC Input Wiring

• Confirm that the available DC bus remains within the specified 88 to 140 VDC input range.
• Use wiring and overcurrent protection appropriate for the installed DC distribution system.
• Keep DC power wiring physically separated from low-level vibration and transducer signal wiring where practical.
• Verify polarity before energizing the module.

Grounding and Maintenance

• Follow the rack manufacturer's grounding arrangement when connecting the power supply.
• Do not modify internal power-supply circuitry in the field.
• Before removing a module from a non-redundant rack, establish that interruption of rack power is acceptable.
• Inspect connectors for contamination, mechanical damage, or loose contacts during replacement.

Power Supply Diagnostic Considerations

The supplied data states that the 3500/15 can provide power-supply health information to the 3500/22M Transient Data Interface. This permits the power subsystem condition to be represented within the broader 3500 monitoring architecture.

Power-supply status should be evaluated separately from machinery measurement channels. A normal vibration channel does not by itself establish that both redundant power-supply paths are healthy.

Frequently Asked Questions

• What input voltage does 114M5329-01 accept?

  The supplied specification identifies an input range of 88 to 140 VDC. The external DC source should remain within this range during normal rack operation.

• What is the output power capacity?

  The supplied data specifies 150 to 300 W, depending on rack loading. A precise operating value should therefore be determined from the actual rack load.

• Can two 3500/15 modules be installed together?

  Yes. The supplied information specifies dual-module redundant operation, with one module acting as the primary source and the other as backup.

• Can the power supply be hot-swapped?

  The supplied information identifies hot-swap capability when a second operational power supply is present. Removal from a non-redundant rack should not be treated as interruption-free.

• Where is the module installed in a 3500 rack?

  The module is a half-height power supply intended for the designated power supply slots on the left side of the 3500 rack.

• Does the module directly power field transducers?

  It supplies regulated power to the 3500 rack electronics. Direct transducer excitation or signal conditioning should be attributed to the applicable monitoring hardware.

• Is power consumption specified for 114M5329-01?

  No separate power-consumption figure is provided in the supplied information. The available data specifies input range and output capacity instead.

• What temperature range is specified?

  The supplied technical data gives an operating range of -30 deg C to +65 deg C. Installation should remain within this stated environmental range.
