Key features



Portability
The lightweight aluminium enclosure combined with the small frame size, castors and handles make the AC30 a highly portable unit. The four 150mm diameter fans produce an evenly distributed airflow over a short distance which enables the resistor elements to be fitted closer to the fans resulting in a compact piece of equipment.
Easy to use
Simple manual control interface enables fast set-up. Analogue meters in the AC30 provide clear real-time display of the voltage, current and frequency, making it quick and easy to understand.
Phase load adjustment
Each phase of each section within the AC30 is individually switched enabling the loading on each phase to be set precisely to the required value.
1 or 3 phase
Featuring dual IEC sockets the AC30 can be loaded from a 3-phase or 1-phase AC supply at up to 30kW or 14.5kW respectively. Easily configure the load bank for the supply to be tested with a simple selector switch.
AC100-CPT load bank
100 kW AC 3-phase or 1-phase
Key features
Light weight, compact load bank providing 100kW of load capacity, power metering and data logging.
Ultra portable
The high power density of this load bank results in a construction that, at only 31kg, can be transported easily.
In addition, the included case with castors and pull handle further enhances manoeuvrability and provides protection when in storage.
Quick setup
Easy connection to the supply under test using Powersafe connectors.
The power connections are located away from the control panel so that operators can stand comfortably in front of the load bank without risk of tripping on cables.
Data logging
The included power meter displays real-time measurements on an LCD screen and simultaneously logs the test data which can be later downloaded over the panel mounted USB socket.
Industrial reliability
The innovative cross-wire coil elements are light and durable, proven in braking applications for locomotives and mining trucks.
AC100 load bank
100kW AC 3-phase | 33kW AC 1-phase
Heavy-duty, robust load bank providing 98.75kW of load capacity, with analogue power metering.



Portability
The heavy duty castors and handle and make this unit easy to move close to the supply under test. In addition, the narrow width of 670mm makes it possible to pass the unit through door ways.
Easy to use
Easy connection to the supply under test using Powersafe connectors. The power connections are located to the side of the control panel so that operators can stand comfortably in front of the load bank.
Site ready
The rugged internal stainless steel frame provides a solid base on which to manoeuvre the unit on-site.
Meter points
Voltage and current banana plug test points provide an easy way to connect external metering eqipment of your choice.
Key features



200kW 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
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. The optional lifting frame provides additional protection to the top of the equipment enclosure and lifting eyes for use when moving the unit with a crane. 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 wire coil and stamped grid 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.
