Description

The Bently Nevada 129478-01 High Voltage dc Power Input Module (PIM) is a Power Input Module designed for machinery protection system power distribution. The module is a special half-height rear card located directly behind the associated 129486-01 High Voltage dc Power Supply Module within the 3500/15 power supply system. It accepts an input voltage of 88 to 140 Vdc, routing power through the internal rack power bus architecture to support machinery monitoring and protection hardware. The module incorporates input fuse protection, where an over-voltage condition causes the fuse to open to protect downstream components, while under-voltage conditions cause no harm to the module.

Features

• Accepts an input voltage range of 88 to 140 Vdc
• Mounts directly behind the associated power supply module in a half-height rear slot
• Contains an integrated over-voltage input fuse protection system
• Supports full 3500 rack current draw up to 2.5 A maximum

Applications

• Bently Nevada 3500 Series Machinery Protection Systems
• Industrial machinery condition monitoring systems
• Redundant and primary power input distribution setups

Installation Guidelines

The power input module is a special half-height module located directly behind the associated power supply module on the left side of the rack. Mount the unit in the dedicated rear rack slot. Ensure proper fuse placement (replacement fuse part number 01720025) prior to applying power. No minimum rack load is required for operation.
