Custom power distribution units, cable assemblies, and wiring solutions engineered for hyperscale, colocation, and edge data centre environments.
Key engineering and supply chain challenges in this sector — and why specialist knowledge matters.
AI and HPC workloads are pushing rack densities beyond 30kW. Power distribution must handle higher currents safely without increasing cabinet footprint.
Tier III and IV facilities demand 2N or 2(N+1) power paths. Every cable assembly and PDU must support concurrent maintainability without single points of failure.
Data centre operators are under pressure to deliver capacity faster. Pre-manufactured, tested power assemblies reduce on-site installation time significantly.
Multi-jurisdiction deployments require UKCA, CE, UL, and sometimes regional certifications. Power products must be certified for the markets they serve.
Purpose-built solutions from Circuit Source for this sector.
Intelligent and basic PDUs designed to your exact outlet configuration, monitoring requirements, and form factor. Single-phase and three-phase options with C13, C19, and commando outputs.
Overhead busbar tap-off assemblies and power whips that connect your distribution boards to rack PDUs. Factory-terminated and tested to reduce on-site installation time.
Pre-terminated copper and fibre cable assemblies for ToR switching, cross-connects, and backbone links. Built to your exact lengths to eliminate cable management waste.
Custom remote power panels that step down facility power to rack-level distribution. Configured for your specific breaker layout, monitoring, and redundancy architecture.
Factory-assembled, tested power modules that arrive on-site ready to install. Reduces hot-work, speeds deployment, and improves quality over site-built solutions.
For ongoing data centre rollouts, we maintain buffer stock of your standard PDUs and cable assemblies so you can call off units as halls come online.
Relevant approvals and quality standards for this sector.
Core capabilities that support this sector.
Bespoke PDU manufacturing for server racks, data centres, and industrial installations — with intelligent monitoring and control.

View serviceEnd-to-end management from concept to sea-freight volume — we handle sourcing, manufacturing, logistics, and quality control.
View serviceYes. We design and manufacture PDUs to your exact specification — outlet count and type (C13, C19, BS 1363, IEC 60309), form factor (0U vertical, 1U/2U horizontal), monitoring level (basic, metered, switched), and input configuration (single-phase, three-phase, dual-feed). We work from your layout drawings or help you spec the right configuration.
We manufacture pre-terminated copper and fibre cable assemblies to your exact lengths and connector types. Pre-terminated cabling reduces on-site installation time by up to 70% compared to field termination and eliminates termination quality variability.
Absolutely. We work with operators on phased deployments — manufacturing and holding buffer stock of your standard PDUs, power whips, and cable assemblies so units can be called off as new halls or pods come online. This avoids long lead times holding up your deployment schedule.
Our custom PDUs range from single-phase 16A units for standard IT racks up to three-phase 63A units for high-density AI/HPC deployments. We also manufacture busbar tap-off assemblies for higher current distribution architectures.
Yes. We can supply PDUs and cable assemblies with UKCA (UK), CE (EU), and UL (North America) certifications. For multi-jurisdiction rollouts, we ensure each product meets the specific standards required for its destination market.
