Features
Redundant Power Paths
Dual AC input channels with automatic <5 ms 切换 ensure uninterrupted power supply to 3500 system modules, eliminating downtime risks from single power source failures.
High Efficiency and Low Heat Generation
With ≥90% efficiency at full load, the module minimizes energy waste and reduces heat output, maintaining stable operating temperatures in enclosed racks.
Comprehensive Fault Protection
Overvoltage, undervoltage, and short-circuit protection mechanisms safeguard connected monitoring modules from electrical damage, extending system lifespan.
Real-Time Diagnostics
Built-in sensors monitor input/output voltages and internal temperatures, with fault alerts via LED indicators and system backplane communication for proactive maintenance.
Seamless System Integration
Designed exclusively for the 3500 series, it integrates with the system backplane to share status data with the system controller, enabling centralized power monitoring.
Function
The primary function of the 3500/93 135785-01 is to provide reliable, redundant power to the Bently Nevada 3500 Machinery Protection System. It converts AC input power to stable 24 VDC for distribution to monitoring modules, ensuring continuous operation of vibration, position, and temperature monitoring functions. In the event of a primary power failure, it automatically switches to the secondary input within 5 ms, preventing data loss or system shutdowns. It also monitors power quality and internal conditions, alerting operators to faults via indicators and system diagnostics to maintain system integrity.
Use
In industrial settings, the module is installed in the 3500 system rack, where it connects to dual AC power sources (e.g., main and backup generators) and distributes 24 VDC power to connected monitoring modules. It works in tandem with the system controller to provide real-time power status updates, enabling operators to monitor power health from centralized control systems. Its redundancy ensures that critical machinery monitoring continues uninterrupted, even during power grid fluctuations or input failures, making it essential for safety-critical applications.
Application Fields
Power Generation
In coal, gas, and nuclear power plants, it powers turbine and generator monitoring systems, ensuring continuous protection of assets critical to grid stability. Redundant power prevents monitoring gaps during utility power fluctuations.
Oil and Gas
For upstream drilling rigs, midstream compressors, and downstream refineries, it provides reliable power to pump and turbine monitors, supporting safe hydrocarbon production and transportation in remote or harsh environments.
Chemical Processing
In chemical plants, it powers reactor and mixer monitoring systems, ensuring uninterrupted fault detection in facilities where equipment shutdowns could lead to hazardous material leaks.
Pulp and Paper
Mills use the module to power roller and motor monitors, preventing production line disruptions caused by power failures in high-speed manufacturing processes.
Water and Wastewater
It ensures continuous power to pump and blower monitoring systems in treatment plants, safeguarding critical infrastructure for public health and environmental protection.
In summary, the Bently Nevada 3500/93 135785-01 is an indispensable component of the 3500 Machinery Protection System, providing the redundant power that underpins reliable machinery monitoring. Its robust design, seamless integration, and fault-tolerant features make it critical for industries where uninterrupted equipment protection is essential to safety, productivity, and operational efficiency.
