Functional Description

3500/15 is a High Voltage AC/DC Power Supply Module developed by Bently Nevada. These power supplies support a wide range of input voltages, converting them into outputs suitable for other 3500 modules. Options include Universal AC, High Voltage DC, and Low Voltage DC Power Supplies, with compatibility limitations between legacy and newer models for both AC and DC configurations.

Features

• The AC and DC Power Supplies are compact, half-height modules designed to fit into specific slots on the left side of the 3500 rack. The rack can be configured with one or two power supplies, supporting any combination of AC and DC units. Each power supply is capable of powering the entire rack independently.
• When two power supplies are installed, the module in the lower slot functions as the primary power source, while the module in the upper slot serves as a backup. In this configuration, the backup power supply seamlessly takes over if the primary supply fails. Removing or inserting a power supply module does not affect rack operation, provided a second power supply is present.
• The Power Supplies accommodate a broad range of input voltages, converting them into outputs suitable for other modules within the 3500 system. The following power supply options are available for the 3500 Series Machinery Protection System:
  • Universal AC Power Supply
  • High Voltage DC Power Supply
  • Low Voltage DC Power Supply

Compatibility

• The Universal AC Power Supply and Power Input Module (PIM) are incompatible with the Legacy 3500 AC Power Supply, High Voltage AC PIM, and Low Voltage AC PIM.
• The High Voltage and Low Voltage DC Power Supplies and their associated PIMs are incompatible with the Legacy 3500 High Voltage and Low Voltage DC Power Supplies and PIMs.

Input Specifications

Universal Voltage AC

The Universal Voltage AC configuration is designed for flexibility and compatibility with a wide range of global power standards. It utilizes the Universal AC Power Supply and the Universal AC Power Input Module (PIM) to handle varying voltage levels seamlessly. This option operates within a nominal input voltage range of 110 to 220 Vac, with an extended operating range of 85 to 264 Vac RMS and a peak voltage capacity of 120 to 373 Vac pk. However, it’s important to note that the Universal AC Power Supply and PIM are incompatible with legacy High Voltage AC or Low Voltage AC units, ensuring optimized performance within modern systems.

High Voltage DC

The High Voltage DC option is ideal for high-performance applications that require stable power delivery at elevated voltage levels. It uses the High Voltage DC Power Supply and the High Voltage DC Power Input Module (PIM). This configuration operates within an input voltage range of 88 to 140 Vdc, making it suitable for demanding industrial environments and critical applications.

Low Voltage DC

Designed for systems with lower voltage requirements, the Low Voltage DC configuration employs the Low Voltage DC Power Supply and the Low Voltage DC Power Input Module (PIM). With an input voltage range of 20 to 30 Vdc, this option provides reliable and efficient power delivery for applications prioritizing compactness and efficiency.

Physical Characteristics

• The Power Supply Module is compact yet robust, designed to fit efficiently within the 3500 system rack. It measures 120.7 mm in height, 50.8 mm in width, and 251.5 mm in depth, with a weight of 1.39 kg. This compact design ensures minimal space usage while delivering reliable performance.
• The Power Input Module complements the Power Supply Module with a streamlined form factor. It measures 120.7 mm in height, 25.4 mm in width, and 114.3 mm in depth, with a lightweight design of 0.34 kg. This module is positioned directly behind its associated power supply, ensuring an organized and efficient setup.

Rack Space Requirements

• The rack is designed to accommodate up to two power supplies, located on the left side in two designated half-height slots. Each slot can house one power supply, and using both slots allows for redundant configurations. This redundancy ensures uninterrupted operation even during maintenance or unexpected failures.
• Each Power Input Module is installed directly behind its corresponding power supply module, occupying a half-height slot. This layout ensures seamless integration and optimized space utilization within the rack, maintaining a clean and organized system architecture.
