Description
Product Description
The 106M1081-01 Universal AC Power Input Module is designed for integration with the Bently Nevada 3500/15 power supply assembly within the 3500 Machinery Protection System. This module conditions incoming AC mains power and delivers stabilized input power to the associated 3500/15 power supply module for rack-wide distribution.
Engineered for continuous industrial operation, the Bently Nevada 106M1081-01 supports a broad universal AC voltage range without requiring manual jumper configuration or input selection adjustments. The module installs directly behind the corresponding 3500/15 power supply in the left section of the rack chassis.
For high-availability applications, the module supports redundant power configurations. When dual Power Input Modules and dual power supplies are installed, the system automatically balances the electrical load while enabling uninterrupted failover during maintenance or power supply replacement procedures.
The module incorporates surge suppression, isolation protection, and low leakage current characteristics to support reliable operation in critical machinery monitoring environments including turbine control systems, compressor trains, process plants, and power generation facilities.
