Banc de charge rackable

Rack-mounted loadbank / Server Emulator (6 kW, 7 kW)

The commissioning agent can manage and run all installed load banks through a supervision software, through which you can send instructions to the load bank (set up the tests based on your commissioning script) and also track and record all data during the tests (Power, Voltage, Current and delta T).
The new load bank generation is able to deliver a 10° to 26° delta T to reproduce the heat generated by the servers.

Banc de charge aérothermes

Floor-standing solutions / Heat load (21 kW)

The best solution to test your data hall if the racks haven’t been deployed. The 21kW load bank also has as a feature the dual power supply to simplify and reduce the testing time in installations with dual busbar.

Compact range with easy power lock connectors, low delta T and smart connected load bank.


Use Case


Location: Germany
Data Hall total power : 551kW
Load banks type : 6kW Smart Load Banks (115 units)
Our new load bank generation, rack-mounted and dual power feed 50%/50% is the only solution available in the market that allows tests on data halls with a 2N configuration.
In this project, the new 6 kW smart server emulators were connected and managed through our supervision software.
The commissioning agents could easily send instructions to the entire fleet such as load ramp-up from 10% to 100% of the total IT load and simulate a complete shut-down. Basically, the commission agent managed to set up the load banks matching the different steps described in the commissioning script using our software.
At the same time, all technical data like P/U/I and delta T were being recorded and charts included in the final commissioning report.
Testing the data hall using this solution creates an accurate representation of the original design and PUE could also be estimated during this test campaign. Cooling system parameters could then also be adjusted and optimized for the different loads, releasing precious information to the operation teams who will soon run the Datacentre.
