AC Loads

Electronic AC Loads & Load Banks

AC loads are devices which receive alternating current (AC) electrical power from a source in an electrical system and are useful for simulating the interaction of other loads within a system and predicting how power sources and loads react to variable currents. AC loads are commonly used for electrical load testing, power system simulation, and AC power testing.

AC loads can be divided into three general categories: portable AC load banks for high-capacity testing starting at 25 kW, programmable AC loads for testing and measuring circuit health, and regenerative AC loads which return energy to the grid with up to 96% efficiency.

ATEC offers affordable AC load rental rates for units with testing capabilities ranging from low to high wattage. Whether you need a resistive load bank or an electronic AC load depends on your testing needs as well as how potentially varied your current will be. We provide products from leading manufacturers like Chroma, NH Research, ASCO/Avtron, and more.

AC load banks are utilized in a wide array of industries, including aerospace, alternative energy, battery manufacturing, military, test laboratories, and research and development. Common applications include UPS testing, generator load testing, power inverter testing, and testing automatic fuses and transfer switches. Companies or government agencies looking to fulfill standards such as DO-160, MIL-STD-704, and IEC 61000 commonly use portable AC load banks for their testing.
