The Bently Nevada 3500/15 Power Supply modules are half-rack components engineered to provide regulated power for the entire 3500 Machinery Protection System, supporting both backplane and connected transducer operations. These high-availability power units are designed for installation in the left-most slots of a 3500 rack, offering flexible configurations for single or redundant power sources to ensure continuous vibration monitoring without a single point of failure. The 3500/15 series accommodates a wide range of input voltages, including Universal AC (85 to 264 Vac), High Voltage DC (88 to 140 Vdc), and Low Voltage DC (20 to 30 Vdc), meeting global industrial power standards. Each module features advanced line filtering to minimize electromagnetic interference and integrated diagnostics to monitor power integrity across the rack. Whether deploying new 3500/05 chassis or replacing legacy power units, these modules provide the stability required for critical rotating machinery protection.
