Product introduction

The ABB BHE055094R0002 is a rugged industrial power supply module belonging to ABB’s renowned GBU series, engineered to deliver consistent 24 VDC power to critical automation components in demanding environments. As a versatile power solution, the BHE055094R0002 bridges AC and DC input sources, making it adaptable to diverse industrial setups—from factory floors with standard mains to remote sites relying on battery systems.

This 15 A module serves as a backbone for automation systems, ensuring stable voltage delivery to PLCs, sensors, and actuators even during input fluctuations. Its robust design, characterized by wide temperature tolerance and comprehensive protection features, positions the ABB BHE055094R0002 as a reliable choice for sectors like manufacturing, energy, and infrastructure, where uninterrupted power is critical to operational efficiency.

Core advantages and technical highlights

Dual input flexibility: The ABB BHE055094R0002 accepts both AC (85-264 VAC) and DC (120-370 VDC) inputs, eliminating the need for separate power supplies in mixed-infrastructure facilities. This versatility shines in remote solar-powered plants, where it seamlessly switches between grid AC and battery DC during power transitions, ensuring control systems remain operational. For example, in a remote water pumping station, the BHE055094R0002 maintains power to flow sensors and valve controllers whether drawing from diesel generators (AC) or stored battery power (DC).

Extreme environment durability: Rated to operate from -40°C to +70°C, the ABB BHE055094R0002 thrives in harsh conditions. Its conformal-coated circuit board resists moisture, dust, and chemical exposure, making it suitable for offshore platforms, steel mills, and cold-storage facilities. In arctic oil pipelines, where temperatures plummet below freezing, the module continues powering pressure monitors without performance loss, ensuring early detection of leaks or blockages.

Efficient power delivery: With ≥89% efficiency at full load, the ABB BHE055094R0002 minimizes energy waste, reducing operational costs and heat buildup in control cabinets. Its low ripple output (≤40 mV p-p) protects sensitive equipment like precision motion controllers in electronics manufacturing, preventing voltage noise from causing calibration drift. This efficiency is particularly valuable in 24/7 operations, where cumulative energy savings add up significantly over time.

Adaptive protection mechanisms: The ABB BHE055094R0002 integrates overload, short circuit, and overvoltage protection. Overload protection handles temporary current spikes (e.g., during motor startups) without shutdown, while short circuit protection uses a self-limiting “hiccup” mode to prevent damage. Auto-recovery after faults eliminates manual resets, critical in unmanned facilities. For instance, in a robotic warehouse, a momentary short in a conveyor motor triggers protection, which clears automatically once the fault is resolved, avoiding production halts.

Typical application scenarios

In automotive assembly lines, the ABB BHE055094R0002 powers robotic painting cells, supplying 24 VDC to position sensors, spray controllers, and safety relays. Its peak current capability (20 A for 5 seconds) handles sudden surges when multiple robots activate simultaneously, preventing voltage drops that could misalign paint nozzles. The module’s resistance to paint fumes and high temperatures (common near curing ovens) ensures long-term reliability.

Renewable energy facilities, such as wind farms, deploy the ABB BHE055094R0002 to power turbine control systems. Mounted in nacelle cabinets exposed to vibration and temperature swings, it delivers stable power to pitch motors and anemometers. During grid outages, its DC input compatibility keeps emergency shutdown systems operational, allowing safe turbine feathering to prevent damage.

Mining operations utilize the ABB BHE055094R0002 in underground control rooms, where it powers gas detectors and conveyor controllers. Its dust-resistant design and wide temperature range withstand the harsh, unconditioned environment, ensuring critical safety systems remain powered. The module’s short circuit protection is vital here—ground faults from water or debris trigger temporary shutdowns, preventing electrical fires while allowing quick recovery once faults are cleared.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing the ABB BHE055094R0002, verify input voltage compatibility (AC or DC) with the power source. Use ESD-safe tools and anti-static wristbands to protect components. Mount on a clean 35mm DIN rail or panel, ensuring the surface can support the module’s weight. Connect AC inputs to L/N terminals or DC inputs to +/- terminals, and secure the PE terminal to a reliable ground. Allow 50mm clearance around the module for ventilation, especially in high-temperature areas.

Maintenance suggestions: Inspect the ABB BHE055094R0002 quarterly for loose connections, corrosion, or overheating signs. Clean dust with compressed air (≤6 bar) to maintain cooling. Check output voltage monthly with a calibrated meter—deviations beyond ±2% of 24 VDC indicate issues. If protection mode activates, isolate the load, resolve the fault (e.g., shorted wiring), then reset by cycling input power. Use only genuine ABB spare parts for replacements to preserve safety certifications.
