Eagle Eye - AC Load Banks

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

Eagle Eye's AC Load Banks are the smallest AC load banks in the industry that offer unmatched capacities with rugged durability. Each load bank is fully self-contained and designed for portable AC load testing that can easily withstand harsh testing environments. Our patent-pending resistor design and assembly make it possible to achieve smaller portable load banks than any one in the industry. The resistors are built for durability and backed by a two year warranty. AC load bank testing can provide predictive failure analysis of backup power systems in any industry. Optional features allow for complete load bank customization for any application.

The AC Load Bank series offers several standard models for continuous load. These models are designed with the most common applications in mind. Full specification sheets on these units are located in the downloads section, located on the right hand of your screen. All load banks come standard with durable finishing, ten foot cables, lifting handles, stainless steel exterior fasteners in a rugged construction frame and a housed in a hard-carrying case.

Every AC Load Bank is easy-to-use with a digital LED display operator control panel. Red and green lights indicate air flow and over-temperature. Straightforward individual fan switches, load step switches, and master load switches make the unit user-friendly. Safety features are equipped on every AC Load Bank for fast acting, branch circuit fuse protection and sensors to prevent overheating and current overload. AC Load banks are used for indoor-use only.
