AC500
500kW resistive load bank
For a high-power load bank, consider the AC500. With 500kW power, it is a highly effective way to verify an electrical supply.
It has the option of 3-phase or 1-phase power ratings, and its ease of use and adaptability to various operating environments make it an excellent choice for many engineers.

Portability
4 heavy-duty castors (2x braked) and 2x fork-lift pockets
Key features
Easy connections
Powerlock style connectors fitted to the main load terminals make connection to the supply under test simple, fast, and secure. The power connections are located away from the control panel.
Portable
Integrated forklift points allow you to easily transport the AC500 load bank to any location.
As heavy duty castors are included as standard, you can move the load bank around on-site. Alternatively, if you would prefer for the design to be installed in a fixed location, the heavy-duty castors can be replaced by mounting brackets with holes for anchor bolts.
Reliable construction
The resistor elements used are from our catalogue of highly robust industrial stamped grid technology using stainless steel. The construction puts the cooling airflow in direct contact with the conductor surface to maximise heat transfer, thus providing the longest possible operating life for the elements.
Optional extras
Remote control
Available for units fitted with Digiload, the remote provides the ability to control a load bank via a wired connection. Housed in a rugged IP66 case it includes a 10” touch screen & emergency stop
Protective PVC cover
Available for additional protection during transport or storage
Supply cables
Lengths of 5m, 10m, 25m as standard. Terminated each end with Powerlock source sockets (for load bank connection) and cable lugs (for connection to supply under test)
Anchor bolt mounting plates
Available for permanent installation. (no-cost option since supplied instead of heavy duty castors)
