Bently Nevada 3500/15-07-07-05(133292-01+133300-01)

This dual DC power supply module provides fully redundant power for the Bently Nevada 3500 monitoring system. It accepts two independent DC inputs and delivers regulated outputs to all rack modules. The 3500/15-07-07-05(133292-01+133300-01) includes both 133292-01 and 133300-01 power supply assemblies.

Core Electrical Specifications

The module accepts dual 24 V DC inputs with a tolerance of ±15% each. It delivers a combined output of 24 V DC at 8 A continuously for heavy loads. Furthermore, the unit provides galvanic isolation between input and output for safety. Each power supply assembly contributes 4 A of output current capacity. The unit achieves 88% typical efficiency across its load range.

Connectivity and Redundant Features

The front panel houses two separate 3-pin terminal blocks for each DC input feed. These terminals accept wire gauges from 0.5 to 4.0 mm² for secure termination. Additionally, the 3500/15-07-07-05 with 133292-01 and 133300-01 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 75 joules of energy for transient ride-through. This storage maintains output regulation for 100 milliseconds following an input 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 1.8 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 3500/15-07-07-05 with 133292-01 and 133300-01 conforms to CE and UL safety certifications.
