    Load Bank Basics

    Load Bank Basics

    A load bank applies an electrical load to the power source and dissipates the resulting electrical energy through resistive elements as heat, provides an electrical load to a power source, such as a generator, battery, or uninterruptible power supply (UPS), in order to test, maintain, or validate its performance.
    Load banks are the best way to replicate, prove and verify the real-life demands on critical power systems.
