Bently Nevada 3300-14-02-20-00 Power Supply

The Bently Nevada 3300-14-02-20-00, also cataloged as the 3300/14 Power Supply, operates as a dedicated hardware component for generating regulated DC voltages within 3300 Machinery Protection System platforms.

Hardware Specifications

Machinery Monitoring & Rotor Dynamics Integration

The 3300-14-02-20-00 establishes stable rail voltages required to execute steady-state eddy-current probe scaling and continuous gap voltage validation (-10 VDC targets) across the backplane. By deploying localized electronic filtering, the internal transformer infrastructure enforces cross-talk suppression between adjacent tracking cards. This regulated distribution network isolates transient supply spikes from sensitive rotor dynamics processing nodes, maintaining electrical integrity across all 12 rack monitor slots.

Frequently Asked Questions

Q: Is a secondary redundant power supply card supported within a single 3300 instrumentation rack?

A: No. The 3300 system architecture is engineered to run its full complement of 12 monitors and transducers from a single 3300-14-02-20-00 module; a second supply card is not utilized.

Q: What happens if the primary line voltage drops below or exceeds the designated input thresholds?

A: Internal under-voltage and over-voltage protection circuits automatically execute a hard shutdown of the module to isolate down-stream monitors. The hardware returns to active status immediately when line levels recover to nominal bounds.

Field Installation Guidelines

• Slot Placement: Install the power supply assembly exclusively into the designated slot 1 position on the far-left side of the chassis. Tighten the faceplate retention screws to ensure ground continuity.

• Input Fuse Inspection: Verify that the integrated input protection fuse rating matches the specified field supply voltage profile prior to energizing the primary supply loop.

• Terminal Ring Isolation: Use insulated crimp ring terminals for all primary power input connections on the rear terminal strip to prevent short circuits and unintended voltage leaks to the frame.
