Bently 3500/15-07

Product Introduction
The 3500/15-07 is a specialized Low Voltage DC power supply module within the Bently Nevada 3500 Machinery Protection System. It is designed to accept a low voltage DC input and convert it into the regulated internal voltages required by other 3500 monitoring modules. This specific model is ideal for industrial environments where only low voltage DC power is available or required.

Description

Bently 3500/15-07

Technical Specifications

  • Module Type: Low Voltage DC Power Supply
  • Input Voltage Range: 20 to 30 Vdc
  • Maximum Input Current: 10.0 A (at 20-30 Vdc input)
  • Module Height: Half-height module

Functional Features

  • Low Voltage DC Compatibility: Specifically engineered for applications utilizing 24 Vdc power distribution systems.
  • Full Rack Powering: A single module is capable of powering the entire 3500 rack, providing flexibility in system design.
  • Hot-Swappable: Supports hot-swapping when configured in a redundant dual-power setup, ensuring zero downtime during maintenance.

Application Scenarios
Widely deployed in small-scale equipment monitoring, underground mining facilities, and specialized industrial sites where low voltage DC power is the primary or backup power source.

Performance Parameters

  • Operating Temperature: -30°C to +65°C (-22°F to +150°F)
  • Storage Temperature: -40°C to +85°C (-40°F to +185°F)
  • Humidity: 95% non-condensing
  • Input Frequency: DC (N/A for AC frequency)

Material Composition
Constructed with high-grade industrial flame-retardant plastics and metal shielding. Internal PCBs are conformal-coated to protect against moisture, salt spray, and corrosive industrial gases.

Structural Characteristics
Half-height form factor designed for installation in the left-side designated slots of the 3500 rack. Features front-panel LED indicators for Power OK and fault diagnostics.

Working Principle
Receives 20-30 Vdc input, utilizes internal DC-DC conversion circuitry with over-voltage and over-current protection, and outputs stable internal DC rails (e.g., +5V, +12V, -12V) to the rack backplane for all connected modules.

Installation Requirements
Must be installed in the left-most half-height slots of the 3500 frame. Proper grounding via the single-point ground switch on the Power Input Module (PIM) is mandatory to prevent ground loops.

Usage Notes
Ensure the external DC power supply is properly fused and regulated. Mixing legacy and new PIM modules is not permitted for this specific DC option. Always verify the input voltage polarity before energizing.
