3500/15 is a High Voltage AC/DC Power Supply Module developed by Bently Nevada. The component is of half-height modules and must be installed in designated slots on the left side of the rack. The component functions as a Power Supply Module for the Bently Nevada Machinery Condition Monitoring system. The Legacy 3500 AC Power Supply, High Voltage AC PIM, and Low Voltage AC PIM are incompatible with the Universal AC Power Supply and PIM (Power Input Module). The Legacy 3500 High Voltage and Low Voltage DC Power Supplies and PIMs are incompatible with the Legacy 3500 High Voltage and Low Voltage DC Power Supplies and PIMs.

3500/15 Features
One or two power supplies with any combination of AC and DC can be housed in the 3500 racks. An entire rack can be powered by either supply. When two power supplies are put in a rack, the one in the bottom slot serves as the primary power source, while the one in the higher slot serves as a backup power source. The second supply, if installed, serves as a backup to the first one. As long as a second power supply is installed, removing or inserting either power supply module has no effect on the rack’s operation. AC and DC Power Supplies accept a variety of input voltages and transform them to voltages that other 3500 modules can use. The 3500 Series Machinery Protection System comes with the following power supplies:

Universal AC Power
High Voltage DC Power Supply
Low Voltage DC Power Supply
