Bently Nevada 3500/15-05-05-05(106M1079-01+106M1081-01)

This AC power supply module provides reliable AC-to-DC conversion for the Bently Nevada 3500 monitoring system. It accepts dual AC inputs and delivers regulated DC power to all rack modules. The 3500/15-05-05-05(106M1079-01+106M1081-01) includes both 106M1079-01 and 106M1081-01 power supply assemblies.

Core Electrical Specifications

The module accepts dual 120–240 V AC inputs with a tolerance of ±10% each. It delivers a combined output of 24 V DC at 8 A continuously for heavy loads. Furthermore, the unit provides galvanic isolation of 1500 V RMS between input and output. Each power supply assembly contributes 4 A of output current capacity. The unit achieves 86% typical efficiency across its load range.

Connectivity and Redundant Features

The front panel houses two separate 3-pin terminal blocks for each AC input feed. These terminals accept wire gauges from 0.5 to 4.0 mm² for secure termination. Additionally, the 3500/15-05-05-05 with 106M1079-01 and 106M1081-01 includes two green LEDs per supply for status indication. The module includes output OR-ing diodes for seamless failover between supplies. Two relay contacts provide remote alarm annunciation for any fault condition.

Energy Storage and Fault Resilience

An internal capacitor bank stores 80 joules of energy for transient ride-through. This storage maintains output regulation for 80 milliseconds following an AC line disturbance. Consequently, the module prevents monitoring system resets during brief power interruptions. The unit also employs individual inrush current limiting per supply assembly. Each assembly includes independent overvoltage and short-circuit protection circuits.

Mechanical Specifications and Environmental Compliance

The dual supply assembly measures 24.1 x 10.5 x 4.5 centimeters and weighs approximately 1.9 kilograms. Its rugged chassis meets Bently Nevada’s shock and vibration standards. The operating temperature range spans -20°C to +65°C with 95% non-condensing humidity. Moreover, the 3500/15-05-05-05 with 106M1079-01 and 106M1081-01 conforms to CE and UL safety certifications.
