Product introduction

The 3BHE055094R0002 is a high-reliability power supply unit from ABB, belonging to the GBU series, specifically designed to deliver stable 24 VDC power to industrial control systems, PLCs, and automation components. As a key member of ABB’s industrial power solutions, 3BHE055094R0002 combines robust engineering with efficient performance to meet the stringent power demands of complex industrial environments.

This 10 A unit accepts a broad input voltage range (100-240 VAC), making it suitable for global deployment without manual voltage adjustments. In industrial setups, 3BHE055094R0002 serves as a critical power hub, ensuring consistent energy delivery to sensitive devices even during voltage fluctuations or harsh operating conditions. Its compact design and DIN rail mounting enable easy integration into control cabinets, optimizing space while providing essential power conditioning for reliable system operation.

Core advantages and technical highlights

Universal input flexibility: 3BHE055094R0002 supports 100-240 VAC input, eliminating the need for regional voltage settings. This is invaluable for multinational facilities or exported equipment, as it adapts seamlessly to North American 110 VAC or European 230 VAC grids. Whether powering a conveyor system in a Mexican factory or a packaging line in Germany, 3BHE055094R0002 maintains stable 24 VDC output, preventing disruptions to connected control systems.

Clean power delivery: With ≤ 50 mV p-p ripple and noise, 3BHE055094R0002 protects sensitive electronics like PLC modules and precision sensors from voltage interference. In semiconductor manufacturing, where microsecond-level signal accuracy is critical, this low-ripple output prevents data corruption in temperature or pressure monitoring systems. Its ≥ 88% efficiency minimizes energy loss, reducing heat buildup in crowded control cabinets—a key factor in extending component lifespans.

Advanced protection mechanisms: 3BHE055094R0002 integrates multiple safeguards to protect both itself and connected equipment. Overload protection handles temporary current spikes (e.g., during simultaneous device startup), while short circuit protection uses a hiccup mode to limit damage, automatically restoring power once faults are resolved. These features reduce unplanned downtime in critical applications such as automotive assembly lines, where even a 5-minute outage can cost thousands in lost production.

Industrial-grade durability: Designed to operate in -25°C to +70°C environments, 3BHE055094R0002 thrives in extreme conditions—from frozen food processing plants to desert-based solar panel factories. Its IP20 rating shields internal components from dust and accidental contact, ensuring long-term reliability in dirty or high-traffic industrial settings. DIN rail mounting ensures secure installation, even in vibrating environments near heavy machinery.

Typical application scenarios

In pharmaceutical manufacturing, 3BHE055094R0002 powers cleanroom control systems, supplying 24 VDC to air pressure sensors, valve actuators, and batch monitoring PLCs. Its low ripple output ensures accurate readings from particulate counters, critical for maintaining FDA compliance. During sterile filling operations, the unit’s overload protection handles sudden current demands from multiple filling pumps, preventing shutdowns that could compromise batch integrity.

Mining operations utilize 3BHE055094R0002 in underground control cabinets, where it powers conveyor belt sensors and ventilation system controllers. Its wide temperature tolerance (-25°C to +70°C) withstands the extreme heat of mine shafts and cold winter conditions at surface facilities. The unit’s short circuit protection is vital here, as dust and moisture can cause wiring faults—3BHE055094R0002 isolates such issues, ensuring ventilation systems remain operational to protect miners.

Renewable energy plants, such as wind farms, rely on 3BHE055094R0002 to power turbine control systems. It supplies 24 VDC to vibration sensors, pitch motor controllers, and data loggers, with its wide input range accommodating fluctuations in generator-supplied AC power. During storm conditions, when voltage spikes are common, the unit’s stable output prevents false readings in wind speed monitors, ensuring turbines shut down safely when necessary.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing 3BHE055094R0002, verify the input voltage matches the mains supply (100-240 VAC). Ensure the DIN rail is clean, securely fastened, and capable of supporting the unit’s weight. Use insulated tools and anti-static wristbands to prevent ESD damage to internal components. Confirm the installation environment stays within -25°C to +70°C and is free from corrosive gases or excessive moisture. Use 16-24 AWG cables for wiring, torquing terminals to 0.5-0.8 Nm—over-tightening risks terminal damage, while loose connections cause overheating.

Maintenance suggestions: Inspect 3BHE055094R0002 quarterly for loose wiring, dust buildup, or discolored components. Clean vents with compressed air (max 5 bar) to maintain cooling efficiency. Periodically measure output voltage with a multimeter—deviations beyond ±5% of 24 VDC indicate potential issues. If 3BHE055094R0002 enters protection mode, identify root causes (e.g., shorted wiring, overloaded devices) before resetting. Replace with genuine ABB units if faults persist, and store spares in -40°C to +85°C environments to preserve performance.
