Bently Nevada 106M1081-01 3500/15 Power Supply Module for Monitoring Racks

This power supply module provides regulated 24 VDC power to the Bently Nevada 3500 monitoring system. It converts high-voltage AC input into stable DC output for all chassis modules. The Bently Nevada 106M1081-01 3500/15 ensures continuous operation in critical rotating machinery protection applications. This unit supports redundant power configurations for enhanced system fault tolerance.

Physical Dimensions and Installation Specifications

This power supply module measures 241 millimeters in width, 52 millimeters in depth, and 152 millimeters in height. The unit weighs approximately 2.10 kilograms for secure rack mounting. It installs directly into the 3500 series chassis using a dedicated backplane connector. The front panel features LED indicators for input presence, output status, and fault conditions.

Input Specifications and Power Conversion

The Bently Nevada 106M1081-01 3500/15 accepts input voltages from 85 to 264 volts AC with automatic range selection. It operates at line frequencies of 47 to 63 hertz without manual adjustment. The module achieves a typical conversion efficiency of 85 percent under full load conditions. Active power factor correction maintains a value above 0.90 across the entire load range. The unit includes an input fuse for overcurrent protection and soft-start circuitry.

Output Characteristics and Load Capacity

This power supply module delivers a nominal 24 VDC output rated at 4.0 amperes continuous current. It maintains output regulation within ±2 percent for stable system performance. The unit provides a total output power of 96 watts for monitoring modules and sensors. Output ripple remains below 50 millivolts peak-to-peak for clean DC power. A remote sense feature compensates for voltage drops in the output wiring.

Protection Features and System Diagnostics

The Bently Nevada 106M1081-01 3500/15 incorporates comprehensive protection for reliable operation. It includes overvoltage protection that shuts down the output during fault conditions. The module features overcurrent protection with automatic restart after fault clearance. Overtemperature protection de-rates the output when internal temperatures exceed limits. Diagnostic LEDs indicate input present, output normal, and fault conditions for rapid troubleshooting.

Component Architecture and Build Quality

This power supply module contains 162 individual components on a multilayer PCB. Key parts include the main transformer, power switching devices, and filter capacitors. The unit uses high-temperature electrolytic capacitors with 105°C ratings for extended life. All critical components meet industrial-grade specifications for demanding environments.

Energy Storage and Hold-Up Capability

The Bently Nevada 106M1081-01 3500/15 includes a 12,000-microfarad capacitor bank for substantial energy storage. This reservoir maintains output voltage for 25 milliseconds during AC power interruptions. The storage array also filters input ripple to less than 40 millivolts peak-to-peak. A bleed resistor safely discharges capacitors when removing the module.
