Bently Nevada 127610-01 AC Power Supply Module

The Bently Nevada 127610-01 AC Power Supply Module is a half-height module designed for use in the 3500 Series Machinery Protection System. It must be installed in the specially designed slots on the left side of the rack. A rack can contain one or two power supplies (either AC or DC), with the second supply serving as a backup. If two power supplies are installed, the lower slot is the primary supply, and the upper slot serves as the backup. Removing or inserting a power supply will not disrupt operation if a second supply is present.

The power supplies accept a wide range of input voltages and convert them into acceptable voltages for the other 3500 modules. There are three versions of the power supply:

• AC Power Supply
• High Voltage DC Power Supply
• Low Voltage DC Power Supply
