Our adjustable AC pure resistive load bank is a dedicated testing device designed to simulate real resistive load conditions for AC power sources. Featuring multi-step adjustable resistive modules, it allows users to manually or automatically set load power levels to test and verify the performance, output capacity, and stability of generators, UPS systems, inverters, and backup power supplies. Available in both portable wheeled and fixed cabinet configurations, it is suitable for factory production testing, on-site commissioning, and regular maintenance checks.

    1.Core Product Advantages

• Pure Resistive Load SimulationBuilt with high-grade resistive alloy elements, the device provides stable and pure resistive loading with a near-unity power factor, ideal for power factor correction testing and standard AC power source performance verification.
• Multi-Step Adjustable Load ControlMulti-stage resistive load groups allow fine step adjustment of load power. The system supports incremental loading from partial load to full rated load, enabling users to simulate various working conditions such as 25%, 50%, 75%, and 100% load operation.
• Multiple Operation & Control ModesThe load bank supports local manual control via the front panel, as well as remote control via PC software or optional mobile monitoring. The system can automatically record voltage, current, power, and temperature data during testing.
• Continuous Operation & Safety ProtectionEquipped with a forced air cooling system, the load bank supports long-term continuous operation. Built-in safety features include over-temperature, over-current, over-voltage, and short-circuit protection, ensuring safe and reliable testing.
• Flexible Customization OptionsStandard power ranges from 5kW to 5000kW, with single-phase or three-phase configurations available. Input voltage, step resolution, and cabinet structure can be fully customized to meet specific testing requirements.
