Bently Nevada 3500/15 133300-01 DC Power Input Module

This DC power input module delivers stable voltage to the entire 3500 monitoring system rack. It integrates seamlessly into the Bently Nevada 3500 monitoring system platform. The unit converts DC input into regulated outputs for all connected modules. Users can rely on consistent power delivery for critical machine protection applications.

Input Voltage Range and Power Conversion

This module accepts a wide DC input range for versatile industrial applications. It operates with input voltages from 90 V to 264 V DC for global compatibility. The conversion efficiency reaches 85% under typical load conditions. This high efficiency reduces heat generation and energy costs. Consequently, the unit extends the service life of nearby electronic components.

Backplane Power Distribution and Capacity

The 3500/15 133300-01 supplies 24 V DC at 4 A to all modules in the 3500 rack. It distributes power through the backplane to each slot for system operation. The total output power reaches 96 W under continuous operation. This capacity supports a fully populated chassis with multiple monitoring modules. Moreover, the module includes internal current limiting for each output rail. This protection prevents damage from accidental overloads or short circuits.

Energy Storage and Ride-Through Performance

This power supply features a hold-up time of 20 ms at full load with DC input. During momentary voltage dips, the module maintains output regulation without interruption. This ride-through capability prevents system resets during brief power disturbances. The unit also incorporates a built-in active inrush current limiting circuit. This feature prevents excessive current draw during power-up sequences. Consequently, the module protects both itself and connected components.

Redundancy and Hot-Swap Capability

This module supports redundant operation with two power supplies in the same rack. Users can install dual power supplies for critical machine protection applications. The unit provides seamless failover if one power supply experiences a fault. The module also supports hot-swapping for maintenance without system shutdown. This capability enables technicians to replace failed units while the system remains operational. Consequently, operators achieve maximum uptime for critical monitoring systems.

Cooling Design and Environmental Durability

The module uses natural convection cooling without any internal fans. This design eliminates mechanical failure points for higher reliability. The operating temperature ranges from -10 °C to 65 °C for most industrial environments. Humidity tolerance spans 0% to 90% without condensation issues. Furthermore, the module carries an IP20 rating for protection against solid objects. Its rugged construction suits power generation, oil and gas, and heavy industrial facilities.

Diagnostic Indicators and Status Monitoring

Two front-panel LEDs provide clear visual status feedback for operators. A green “Power” LED confirms the presence of output voltage. A red “Fault” LED illuminates during overvoltage or overtemperature events. These indicators simplify troubleshooting without external measurement tools. Moreover, the module provides remote signaling capability for centralized monitoring. This feature enables plant-wide notification of power supply issues.
