Load Banks
Load banks are essential tools for testing, commissioning and validating data centre power infrastructure. We supply and integrate load bank solutions that enable accurate testing of generators, UPS systems, power distribution and cooling systems under controlled conditions.
Our Oper8 in-house developed solution sets to mimic the workings of a server by generating heat load within the IT rack to simulate realistic scenarios of a conventional air-cooled data centre. These rack mounted load banks fit within the standard IT rack 19” rails and provide 6kW of heating that can be loaded in 1kW increments.
Need to test higher density racks? Then simply add more load banks into the rack. A 6U chassis offers 6kW of simulated load capacity!
