Product Introduction
The ABB BHE055094R0002 represents ABB’s advanced regenerative drive technology designed for energy-intensive industrial applications. As part of the ACS880 multidrive system’s Grid Feeding Unit (GFU) series, this converter enables bidirectional power flow, efficiently converting braking energy from motors into clean AC power fed back to the electrical grid. With its 94kW continuous rating, the ABB BHE055094R0002 eliminates the need for traditional braking resistors while significantly reducing energy consumption in applications with frequent deceleration cycles.
Engineered for seamless integration with ABB’s ACS880 drive cabinets, the ABB BHE055094R0002 features active front-end (AFE) technology that maintains near-unity power factor (>0.98) during regeneration. Its IGBT-based topology ensures precise DC bus voltage control even during rapid load changes. The unit serves as a cornerstone for sustainable operations in material handling, process manufacturing, and heavy industry, where it transforms kinetic energy into reusable electricity while reducing cooling requirements and carbon footprint.
Core Advantages and Technical Highlights
Ultra-Efficient Energy Recovery: The ABB BHE055094R0002 delivers industry-leading regeneration efficiency (>98.2%), recovering up to 94kW of braking energy. Hybrid SiC-IGBT technology minimizes switching losses, enabling annual energy savings exceeding €25,000 in crane applications.
Advanced Grid Support: Incorporates active harmonic filtering (THD<3%) and low-frequency damping to stabilize weak grids. Voltage dip ride-through (100% voltage recovery in 15ms) prevents nuisance tripping during grid disturbances.
Seamless Drive Integration: Synchronizes with ACS880 drives via optical DriveBus with <500μs latency. Automatic mode transition between motoring/regeneration ensures DC bus stability during emergency stops.
Compact Thermal Management: Patented asymmetric heatsink design with temperature-optimized air ducting. Smart fan control reduces acoustic noise by 8dB at partial loads while maintaining junction temperatures 15°C below critical limits.
Cybersecurity Hardened: Secure firmware boot sequence with digital signatures prevents unauthorized code execution. Role-based access control integrated with DriveCom communication protocols.
Predictive Maintenance Ready: Embedded condition monitoring tracks IGBT aging, capacitor ESR degradation, and fan performance. Outputs prognostic data via Modbus TCP for integration with ABB Ability™ platform.
Typical Application Scenarios
Steel Mill Cranes & Hoists: In slab handling and coil transfer applications, the ABB BHE055094R0002 recovers >60% of lowering energy, reducing substation loading by 150kVA during peak operations.
Mine Conveyor Systems: For downhill ore transport, regenerates gravitational energy at 94kW continuous, eliminating brake wear and reducing diesel generator dependency in remote sites.
Test Bench Dynamometers: Provides precise torque control while feeding back 92% of absorbed energy during automotive/marine engine testing cycles.
Centrifugal Decanters: In wastewater treatment plants, captures inertial energy during bowl deceleration, achieving 35% net energy reduction in sludge processing.
