Bently Nevada 169337 External Power Supply

The 169337 external power supply from Bently Nevada feeds machinery protection racks and field transmitters with regulated DC power. Plant engineers install this unit whenever a monitoring cabinet needs a dependable supply outside the main rack. Consequently, it keeps vibration, position, and speed channels running without interruption.

Functional Overview

This unit converts AC mains power into clean, isolated DC rails for monitoring equipment. Therefore, it shields sensitive measurement circuits from ripple and line transients. The 169337 also monitors output status and signals faults through front-panel indicators. Meanwhile, its onboard energy storage sustains output during brief input interruptions.

Installation and Handling Notes

Always verify input voltage and polarity before connecting the 169337 to a live cabinet. In addition, inspect bulk capacitors for swelling or leakage during routine service. Tighten all power terminals to the specified torque value. Finally, record measured rail voltages in your maintenance log.
