The GROADA AC 346V 50 kVA RL Load Bank is a high-precision testing system designed to simulate both resistive and inductive loads for generators, UPS systems, turbines, and electrical power networks.
With a power factor of 0.8 lagging, this unit accurately reproduces real-world load conditions, allowing engineers to verify performance, detect weaknesses, and prevent failures before they occur.
Built for industrial, marine, data center, and energy applications, the GROADA RL Load Bank combines advanced control technology, modular construction, and robust safety systems—delivering consistent, repeatable, and safe load testing results in any environment.
Simulates both resistive and inductive components simultaneously, providing a realistic representation of motor-driven and transformer-based systems.
Offers resistive-only, inductive-only, or combined RL operation for flexible testing modes.
Ideal for generator commissioning, factory acceptance testing (FAT), UPS maintenance, and system validation under lagging power factor conditions.
Helps ensure that your equipment performs efficiently under real operational demands—not just laboratory conditions.
Fine-tuned load step increments (e.g., 1 kW / 1 kVAR) for accurate load adjustment and gradual system ramp-up.
Modular resistive and inductive sections allow independent operation, easy calibration, and simplified servicing.
Parallel connection capability enables capacity expansion beyond 50 kVA for large-scale test systems.
Ensures smooth, stable transitions during load switching—reducing stress on test subjects and extending lifespan.
Integrated digital PLC control system with high-precision data acquisition.
Real-time display and recording of voltage, current, power, power factor, frequency, and temperature.
Optional remote control and data logging via Ethernet / RS485 / wireless interfaces.
Automated test sequences with programmable ramp rates, dwell times, and step loads—ideal for repetitive testing and certification workflows.
Safety interlocks prevent unintended operation during testing or maintenance.
Heavy-duty, powder-coated steel enclosure ensures durability and corrosion resistance in harsh environments.
Designed for indoor or outdoor operation, with high-efficiency forced-air cooling and thermostatically controlled fans.
All circuits are fully protected by overload breakers, fuses, and fault-detection systems.
Equipped with over-temperature, airflow failure, overload, emergency-stop, and load-dump protection mechanisms.
Engineered to operate continuously at full load without performance degradation, ensuring long service life and stable accuracy.
Regular load bank testing prevents wet stacking—the accumulation of unburned fuel and carbon deposits in diesel engines.
By simulating realistic load conditions, it ensures complete combustion and optimal generator efficiency.
Detects voltage drops, connection issues, insulation degradation, and cooling inefficiencies before they cause failures.
Essential for routine preventive maintenance in telecom, healthcare, data centers, and utility power plants.
Built to meet or exceed international electrical and safety standards.
Each GROADA load bank undergoes full functional testing, calibration, and quality assurance before shipment.
Optional CE / ISO / UL-ready configurations available for compliance with global certification requirements.
Backed by GROADA’s comprehensive after-sales support, including commissioning assistance, spare parts supply, training, and remote diagnostics.
