ABB GBU72 3BHE055094R0002

Product introduction

The ABB GBU72 3BHE055094R0002 is a high – performance industrial DC power supply module, belonging to ABB’s GBU series of robust power solutions. Designed to deliver stable and reliable 24 VDC power, it serves as a critical energy source for sensitive industrial control systems, including PLCs, DCS modules, and sensors in automated production environments.

As a three – phase input module, the GBU72 3BHE055094R0002 efficiently converts AC power from the industrial grid into clean DC power, minimizing voltage ripples and electromagnetic interference (EMI) that could disrupt control system operations. In complex automation setups, such as automotive assembly lines or chemical processing plants, the ABB GBU72 3BHE055094R0002 ensures continuous power supply to key components, reducing the risk of unplanned downtime caused by power fluctuations. Its compact design and high power density make it suitable for installation in space – constrained control cabinets, integrating seamlessly with other ABB automation components.

Core advantages and technical highlights

High power density: With a 72 A output current in a 220 mm × 160 mm × 100 mm form factor, the ABB GBU72 3BHE055094R0002 offers exceptional power density. This allows it to replace multiple lower – current power supplies in systems requiring high current, such as large – scale PLC racks with dozens of I/O modules. In a semiconductor manufacturing facility, for example, a single GBU72 3BHE055094R0002 can power an entire control cabinet of wafer handling robots, eliminating the need for redundant wiring and reducing cabinet footprint by 30%.

Comprehensive protection mechanisms: Equipped with multi – layer protection, including overvoltage, overcurrent, short – circuit, and overtemperature safeguards, the GBU72 3BHE055094R0002 ensures system safety in abnormal conditions. If a short – circuit occurs in a connected sensor loop, the module instantly shuts down output current, preventing damage to both the power supply and downstream components. It automatically resumes operation once the fault is cleared, reducing manual intervention. In a water treatment plant, this feature protects expensive flow meter controllers from electrical faults caused by moisture ingress.

Wide temperature resilience: Operating reliably from – 25°C to + 70°C, the ABB GBU72 3BHE055094R0002 adapts to extreme environments. In cold storage warehouses where control cabinets are exposed to subzero temperatures, or in steel mills with ambient heat exceeding 50°C, the module maintains stable output voltage (within ±2% of 24 VDC). Its forced air cooling system, with a variable – speed fan, adjusts airflow based on internal temperature, balancing cooling efficiency and noise levels—critical for noise – sensitive environments like food packaging lines.

High efficiency and low EMI: Boasting ≥92% efficiency at full load, the GBU72 3BHE055094R0002 minimizes energy waste, reducing operational costs in 24/7 industrial settings. A 100 kW control system using ten GBU72 3BHE055094R0002 modules can save over 8,000 kWh annually compared to 85% efficiency alternatives. Additionally, its advanced EMI filtering meets EN 61000 – 6 – 2 standards, preventing interference with nearby sensitive equipment like frequency converters or precision measurement tools in pharmaceutical production lines.

Typical application scenarios

Industrial automation control systems: In an automotive paint shop, the ABB GBU72 3BHE055094R0002 powers the PLCs, servo drives, and proximity sensors that control the robotic painting arms. The module’s stable 24 VDC output ensures precise movement of the robots, maintaining consistent paint thickness and reducing defects. Its overcurrent protection is critical here—if a sensor cable is damaged by paint overspray, the GBU72 3BHE055094R0002 shuts down before the fault affects the robot’s control board, preventing costly rework.

Power distribution substations: Substations rely on the GBU72 3BHE055094R0002 to supply DC power to protection relays, SCADA communication modules, and alarm systems. Operating in outdoor control cabinets exposed to temperature swings from – 20°C to + 60°C, the module’s wide temperature range ensures uninterrupted power to these safety – critical systems. During grid faults, its fast response to voltage fluctuations (≤10 ms recovery time) keeps the relays operational, enabling rapid fault isolation and reducing blackout durations.

Food and beverage processing: In a dairy processing plant, the ABB GBU72 3BHE055094R0002 powers the control systems for pasteurizers, filling machines, and conveyor belts. Its low EMI ensures that nearby pH sensors and flow meters (sensitive to electrical noise) provide accurate readings, maintaining milk quality. The module’s sealed fan design prevents dust and moisture ingress, complying with the plant’s hygiene standards, while its efficiency reduces heat output—important in temperature – controlled clean rooms where excessive heat could spoil products.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the ABB GBU72 3BHE055094R0002, ensure the control cabinet is clean, dry, and free from conductive dust. Verify the ambient temperature is within – 25°C to + 70°C, and cabinet ventilation provides at least 50 CFM airflow. Use torque – controlled screwdrivers (set to 1.5 – 2 Nm) for wiring terminals to avoid loose connections. The module must be mounted vertically (within ±15°) to ensure proper heat dissipation—horizontal mounting can reduce cooling efficiency by 20%. Connect the three – phase input (380 – 480 VAC) via 10 AWG wires, and the 24 VDC output via 6 AWG wires for full 72 A capacity. Label all wires clearly to prevent phase reversal during commissioning.

Maintenance suggestions: Inspect the GBU72 3BHE055094R0002 monthly for dust accumulation on the fan grille—use compressed air (max 5 bar) to clean if needed. Check output voltage with a calibrated multimeter; deviations beyond ±2% of 24 VDC indicate potential issues. Monitor the module’s status LED: green indicates normal operation, red signals a fault (refer to the manual for error codes). Replace the fan every 5 years (or if unusual noise occurs) using ABB’s genuine fan kit (part no. 3BHE055094R0003) to maintain cooling performance. In case of a short – circuit fault, disconnect input power for 5 minutes before resetting to avoid thermal stress on components. Always use ABB – approved spare parts to preserve warranty coverage.
