Calibration, rental and applications support

Test equipment is only as useful as its last calibration. We calibrate power analysers, sources, loads and safety testers in our own laboratory, rent power sources and loads for qualification campaigns and short projects, and support you in choosing an appropriate test configuration for your equipment.

What testing does data centre power equipment need?

Every stage between a data centre's grid connection and its processors converts, distributes or protects power, and the equipment at each stage is typically tested more than once: characterisation in R&D, end-of-line and electrical safety testing in production, and factory or site acceptance before handover. The common thread is reproducing real supply conditions at the input, such as dips, interruptions, frequency changes and harmonics, applying realistic loads at the output, and measuring efficiency and power quality accurately in between.

AI workloads are changing what that testing has to cover. GPU racks draw far more power than conventional server racks and can change their load quickly, which puts more weight on load-step and transient testing of power shelves, DC-DC converters and battery backup units. With 48 V busbars now common in hyperscale racks and 800 V DC distribution emerging for new AI designs, high-voltage bidirectional DC supplies and fast regenerative loads are becoming part of the test bench.

In the UK, data centres were designated Critical National Infrastructure in September 2024, and new capacity continues to be planned. For UK designers and manufacturers of UPS, switchgear, busbar and power conversion equipment, that is likely to mean more qualification and acceptance testing. Tell us what your applications are, with ratings and target standards, and we can support you in choosing an appropriate test configuration, whether you buy, rent or need existing equipment calibrated.
