Product introduction

The ABB 73BHE055094R0002 GBU72 is a high-performance industrial power supply module engineered to deliver stable 24 VDC power to a wide range of automation components, including PLCs, I/O modules, servo drives, and industrial sensors. As a flagship model in ABB’s GBU series, the 73BHE055094R0002 GBU72 combines rugged construction with advanced power regulation technology, making it ideal for harsh industrial environments where reliability is paramount.

This 15 A module supports both AC and DC input voltages, providing flexibility for diverse installation scenarios—from factory floors with standard AC mains to remote sites with DC power sources. In complex automation systems, the ABB 73BHE055094R0002 GBU72 acts as a central power hub, ensuring consistent voltage delivery even during input fluctuations or heavy load changes. Its robust design and comprehensive protection features make it a trusted choice for critical applications in sectors such as automotive manufacturing, oil and gas, and renewable energy.

Core advantages and technical highlights

Dual input capability: The ABB 73BHE055094R0002 GBU72 accepts both AC (85 – 264 VAC) and DC (120 – 370 VDC) inputs, eliminating the need for separate power supplies in mixed – infrastructure environments. This versatility is particularly valuable in remote industrial sites, such as solar – powered pumping stations, where it can seamlessly switch between grid AC and battery DC power. For example, in a desert solar farm, the 73BHE055094R0002 GBU72 ensures uninterrupted power to control systems whether drawing from solar panels (DC) or backup generators (AC).

Extreme environment resilience: With an operating temperature range of – 40°C to + 70°C, the ABB 73BHE055094R0002 GBU72 thrives in the harshest conditions. It can withstand extreme cold in arctic oil pipelines, high heat in steel mills, and rapid temperature fluctuations in outdoor enclosures. The module’s conformal coating protects internal components from moisture, dust, and chemical contaminants, ensuring long – term reliability in applications like offshore drilling platforms or chemical processing plants.

High efficiency and low noise: Boasting ≥ 90% efficiency at full load, the ABB 73BHE055094R0002 GBU72 minimizes energy waste and heat generation, reducing cooling requirements in control cabinets. Its ultra – low ripple output (≤ 30 mV p-p) protects sensitive electronics, such as precision motion controllers in semiconductor manufacturing equipment, from voltage noise that could cause positioning errors. This combination of efficiency and clean power translates to lower operational costs and improved system performance.

Enhanced protection features: The ABB 73BHE055094R0002 GBU72 incorporates a comprehensive suite of protection mechanisms. Overvoltage protection prevents damage to connected devices from voltage spikes, while overload and short circuit protection safeguard the module itself. The auto – recovery function eliminates the need for manual resets after temporary faults, reducing downtime in critical systems. For instance, in a robotic assembly line, a momentary short circuit in a gripper motor will trigger the module’s protection, which then automatically restores power once the fault is cleared, allowing production to resume without operator intervention.

Typical application scenarios

In automotive production facilities, the ABB 73BHE055094R0002 GBU72 powers the control systems of robotic welding cells. It supplies stable 24 VDC to PLCs, weld controllers, and position sensors, ensuring precise coordination of welding torches. During peak production, when multiple robots operate simultaneously, the module’s 20 A peak current capability handles sudden current surges, preventing voltage drops that could disrupt weld quality. Its wide operating temperature range also allows installation in the warm environment near welding stations without performance degradation.

Oil and gas refineries utilize the ABB 73BHE055094R0002 GBU72 to power instrumentation and valve control systems in hazardous areas (when installed in certified enclosures). The module’s ability to accept DC input makes it suitable for locations powered by battery backups, ensuring critical systems like pressure transmitters and emergency shutdown valves remain operational during mains power outages. Its low ripple output ensures accurate sensor readings, which is vital for maintaining safe operating pressures in refining processes.

Renewable energy plants, such as wind farms, rely on the ABB 73BHE055094R0002 GBU72 to power SCADA components and turbine control systems. Mounted in weatherproof cabinets at the base of wind turbines, the module withstands extreme temperature variations and vibration. It delivers stable power to pitch control sensors and yaw drive controllers, ensuring optimal turbine performance. The 73BHE055094R0002 GBU72‘s dual input capability also allows it to switch between turbine – generated AC power and grid power, enhancing system redundancy.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the ABB 73BHE055094R0002 GBU72, confirm that the input voltage (AC or DC) matches the available power source. Ensure the mounting surface (DIN rail or panel) is clean, flat, and capable of supporting the module’s weight. Use ESD – safe tools and wear anti – static wristbands to prevent damage to internal components. For AC input, connect the live and neutral wires to the L and N terminals; for DC input, use the + and – terminals. Always connect the protective earth (PE) terminal to a reliable ground source. Allow at least 50 mm of clearance around the module for ventilation, especially in high – temperature environments.

Maintenance suggestions: Inspect the ABB 73BHE055094R0002 GBU72 every six months for loose connections, corrosion, or signs of overheating. Clean dust and debris using compressed air (maximum 6 bar) to maintain cooling efficiency. Measure the output voltage regularly with a calibrated multimeter; a deviation of more than ±2% from 24 VDC indicates a potential problem. If the module enters protection mode, disconnect the load, identify the cause (such as a short circuit or overload), rectify it, and then reset the module by cycling the input power. When replacing components, use only genuine ABB spare parts to ensure compatibility and maintain safety certifications.
