Introduction
The model 16925-15 is a Power Supply Module for the Bently Nevada 3300 Monitoring System. This module is a critical system component that converts the plant's incoming AC or DC power to the clean, regulated, and isolated DC voltages required by all the monitoring modules within a 3300 rack. The -15 suffix typically indicates a specific hardware configuration, often related to the input voltage range (e.g., 85-264 VAC). Its reliable operation is fundamental to the accuracy and availability of the entire machinery protection system, ensuring that vibration, temperature, and position modules receive stable power.
