It mounts directly into the 3500 series chassis via a high-density backplane connector. The front panel includes LED indicators for input status and output health. A removable terminal block simplifies all external field wiring connections.

Input Specifications and Conversion Efficiency

The Bently Nevada 3500/15 106M1079-01 accepts input voltages from 85 to 264 VAC with worldwide compatibility. It operates at line frequencies of 47 to 63 hertz without any manual intervention. The module achieves a typical efficiency of 86 percent under nominal load conditions. Inrush current limiting circuitry prevents unwanted breaker tripping during startup. The unit also includes a replaceable input fuse for enhanced protection.

Output Characteristics and Power Ratings

This power supply module delivers a 24 VDC output rated at 4.5 amperes continuous current. It maintains output voltage regulation within ±1.5 percent across all load conditions. The unit provides a total power capacity of 108 watts for the entire chassis. Output ripple and noise remain below 45 millivolts peak-to-peak. A remote sensing feature compensates for voltage drops along the output cables.

Protection Features and Diagnostic Capabilities

The Bently Nevada 3500/15 106M1079-01 incorporates multiple protection mechanisms for safe operation. It includes overvoltage protection that immediately disables the output during faults. The module features current limiting for short-circuit and overload conditions. Overtemperature protection reduces the output when internal temperatures rise excessively. Front-panel LEDs provide clear visual indication of input power, output status, and any fault conditions.

Component Architecture and Build Quality

This power supply module contains 165 individual components on a high-quality PCB. Key parts include the main isolation transformer, power MOSFETs, and filter capacitors. The unit uses long-life electrolytic capacitors rated at 105°C for extended durability. All power semiconductors mount to an aluminum heatsink for optimal thermal management.

Energy Storage and Ride-Through Capability

The Bently Nevada 3500/15 106M1079-01 includes a 13,000-microfarad capacitor bank for substantial energy reserves. This reservoir sustains output voltage for 30 milliseconds during momentary power interruptions. The capacitor array also attenuates input ripple to below 35 millivolts peak-to-peak. Internal bleeder resistors discharge capacitors safely after module removal.
