GROADA RL Series 6 kW Resistive-Inductive Load Bank

Accurate AC Load Simulation at 0.8 Power Factor

Reliable | Compact | Technically Precise

The GROADA RL Series 6 kW Resistive-Inductive Load Bank is a professional AC test solution designed for precise load simulation at 0.8 power factor. It provides accurate, repeatable performance testing for generators, UPS systems, inverters, transformers, and power control equipment. Built with high-quality resistive and inductive elements, this unit replicates real-world mixed loads to verify true power behavior under reactive conditions.


Key Features & Advantages

1. True Resistive-Inductive Simulation

Unlike resistive-only load banks, the GROADA RL model integrates both resistive (R) and inductive (L) circuits, offering a lagging power factor of 0.8. This enables realistic testing of equipment where reactive current is critical—such as motor-driven systems, industrial drives, or power distribution networks.

Benefits:

  • Accurately assess generator voltage regulation and frequency response

  • Validate UPS and inverter performance under inductive loading

  • Ensure system stability under real-world operating conditions


2. Precision Load Steps & Fine Control

The RL 6 kW load bank offers finely tuned load increments (as low as 0.1 kW / 0.1 kVAR) for smooth ramping and precise test profiling.
Operators can easily simulate step-load changes, transient conditions, or progressive loading to observe system reactions without overshoot or instability.


3. Rugged Design for Industrial Environments

Built to GROADA’s high manufacturing standards, this model is suitable for both indoor and outdoor operation.
Construction Highlights:

  • Heavy-duty, powder-coated steel enclosure

  • Corrosion-resistant finish and reinforced frame

  • Independent compartments for resistive and inductive sections

  • Forced-air cooling with airflow monitoring

  • Optional anti-condensation heater for cold / humid environments


4. Advanced Protection & User Safety

Safety and reliability are embedded into every GROADA design.
Protection Functions Include:

  • Over-temperature and over-current protection

  • Airflow failure detection with automatic shutdown

  • Phase imbalance protection

  • Emergency stop (E-Stop) switch

  • Real-time fault indicators and audible alarms

These safeguards ensure continuous protection of both equipment and personnel during testing.


5. Flexible Integration & Scalability

The 6 kW RL Load Bank can operate as a stand-alone unit or be paralleled with other GROADA load banks for higher-capacity applications.
Its modular design is ideal for:

  • Laboratory testing environments

  • Service / rental fleet configurations

  • On-site commissioning projects


6. Accurate Measurement & Data Logging

Integrated metering supports real-time monitoring of:
Voltage, Current, Power (kW), Reactive Power (kVAR), Power Factor, Frequency, and Energy.
Data can be logged for quality assurance, trend analysis, and compliance documentation—supporting consistent performance verification across test cycles.
