APS 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 anyone in the industry. The resistors are built for durability and are 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.

For continuous load, the AC Load Bank series includes several standard models. These models are intended for the most common applications. Full specifications for these units can be found in the downloads section on the right side of your screen. All load banks include durable finishing, ten-foot cables, lifting handles, stainless steel exterior fasteners, a rugged construction frame, and a hard-carrying case as standard.

Every AC Load Bank has an easy-to-use operator control panel with a digital LED display. Red and green lights indicate airflow and overheating, respectively. Individual fan switches, load step switches, and master load switches make the unit simple to use. Every AC Load Bank includes safety features such as fast-acting branch circuit fuse protection and sensors to prevent overheating and current overload. AC load banks are only used indoors. 


Key Features 

  • Small and simple to use
  • dependable load element
  • Temperature and overvoltage protection
  • 0-40k continuous variable
  • High-speed testing of generator and UPS voltage, current, and transient voltage waveforms
  • Large TFT touch screen, simple operation, and a clear display of testing data and waveforms
  • Power is continuously adjustable from 0 to 40kW, and current is adjustable from 0 to 60A.

Safety features include: 

All three phases of all load steps have fast-acting branch circuit fuse protection. 
  • Control circuit fused at 120 volts 
  • If there is a loss of cooling air, an air pressure switch prevents the load from being applied. 
  • If an over-temperature condition is detected, the load is automatically removed. 
  • Current overload protection is used to protect the Blower Motor circuit. 
  • On appropriate access panels and doors, operator warning and caution statements are located.
