Hardware Specifications

Rotor Dynamics & Signal Conditioning

• Eddy-Current Probe Scaling Protection: Provides stable DC rail voltages to monitor modules, ensuring that eddy-current displacement sensors maintain precise scaling and linear output responses across transient operational ranges.
• Gap Voltage Validation: Supplies regulated power essential for maintaining -10 VDC target values on proximity probes, preventing signal drift during rotor dynamics analysis.
• Cross-Talk Suppression: Incorporates internal line noise filtering and galvanic segregation to minimize electrical noise propagation between high-power actuator loops and sensitive vibration monitoring channels.

Field Installation Guidelines

• Rack Slot Allocation: Install the power supply and associated PIM exclusively into the left-most slots reserved for power supplies within the 3500 instrument rack.
• Redundant Configuration: When utilizing dual power supplies, place the primary supply in the lower slot and the backup supply in the upper slot to achieve instantaneous failover without rack disruption.
• Terminal and Grounding Security: Fasten all input line terminations securely to the PIM rear connectors while maintaining low-impedance chassis grounding to prevent ground loops and electromagnetic interference.

Frequently Asked Questions

• What input voltage range does the 3500/15-01 universal AC supply support?

  The universal AC supply supports 85 to 264 Vac rms in non-hazardous areas and 85 to 250 Vac rms in hazardous areas, with a frequency range of 47 to 63 Hz.

• How does the module handle under-voltage conditions?

  An under-voltage condition causes no physical harm to the power supply or the power input module (PIM).

• What happens during an over-voltage condition on the input line?

  An over-voltage condition causes the internal fuse on the PIM to open, protecting downstream circuitry.

• Can dual power supplies be operated from different voltage sources?

  Dual supplies can utilize separate voltage sources, such as combining a 120 Vac primary supply with an uninterruptible 24 Vdc backup source.

• What is the maximum full rack current draw for the universal AC power supply option?

  The maximum full rack current draw is 2.8 A rms.

• How is normal operation of the power supply indicated on the hardware?

  A front-panel green Supply OK LED illuminates when the power supply is operating properly and all output voltages are within specifications.

• Are 3500 power supplies hot-swappable?

  Power supply modules are designed to be inserted or removed from the rack backplane while rack power is applied, provided safety precautions for live terminals are observed.

• Is the universal AC power supply compatible with legacy high-voltage AC units?

  The universal AC power supply and power input module are not compatible with legacy high-voltage AC or low-voltage AC units.
