AC1350 load bank
1350kW AC 3-phase | 300kW AC 1-phase
Key features
1350kW load bank with integrated touchscreen control system providing the ultimate way to verify an electrical supply.
Advanced interface
The unique Digiload control system provides detailed insight into how the supply under test responds to load changes. All test data is recorded within the system and is exported instantly in .csv format when connecting a USB flash drive. The integrated touchscreen interface can be used to manually change the load power level or setup an automated schedule of load steps. Once created, load step sequences can be saved and recalled at any time.
Quick setup
Easy access to the generous cable entry compartment via a hinged, padlock-able door makes connection to the supply under test simple, and secure. The power connections can run under the control panel so that operators can stand comfortably in front of the load bank without tripping over cables. With power connected, the 10” intuitive touchscreen interface enables load to be applied rapidly, with measurements displayed in real time.
Modular system
Multiple 1350kW modules can be installed on a common base frame to achieve the desired total power level. The control system can be a shared common on or separate. Transport to any location with integrated fork lift points. An optional base lifting frame can be provided where 2 or more modules are required and provides lifting eyes when crane lifting is preferred.
Robust construction
The resistor elements used are from our catalogue of robust, industrial level stamped grid and flat strip technologies using high grade 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. With decades of service in industry, electricity transmission and distribution systems the element technologies provide the highest level of reliability for our product.

Optional extras
Remote Control the Digiload remote provides the ability to control an enabled load bank via a wired connection of up to 100m in length. It can also be used as the single point of control for a network of load banks. Housed in a rugged IP66 case (IP54 when open) it includes a 10” touch screen, emergency stop, on/off push button, and 2 x USB ports.
Network capability when this hardware capability is enabled the load bank can be connected with other load banks via Modbus TCP to create a centrally controlled network.
Base lifting frame available where 2 or more 1350kW modules are to be installed in the same location. This frame allows the load bank.
