AC100-PRO load bank

100kW AC 3-phase | 33kW AC 1-phase

Key features

 
 
 

Heavy-duty, robust load bank providing 100kW of load capacity, with digital control, power metering and data logging.

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

Powersafe 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 so that operators can stand comfortably in front of the load bank without tripping over cables. With power connected, the 7” intuitive touchscreen interface enables load to be applied rapidly, with real time measurements displayed immediately.

Portable

Transport to any location with integrated fork lift points. Move around on-site using heavy duty castors, which are included as standard. Alternatively, the design can be installed in a fixed location, when requested, the heavy duty castors are replaced with mounting brackets with holes for anchor bolts.

Robust construction

The resistor elements used are from our catalogue of highly robust industrial stamped grid and tape wound mica card technologies 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. 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 a load bank via a wired connection. It can also be used as the single point of control for a network of load banks. Housed in a rugged IP66 case it includes a 10” touch screen, emergency stop and 2 x USB  data 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.

Protective PVC cover available for additional protection during transport or storage.

Supply cables made to order to the desired length and with supply side connection method to suit the intended use.

Anchor bolt mounting plates available for permanent installation. (no-cost option since supplied instead of heavy duty castors)
