As demand for data storage and processing accelerates, energy costs are becoming a critical concern for colocation customers. Without precise monitoring, businesses risk overpaying for power consumption, facing inefficiencies, and missing sustainability targets.
The Challenge: Transparent and Accurate Energy Billing
Colocation customers typically pay for power usage, but without precise rack-level metering, costs can be estimated rather than exact. Inefficient servers, unexpected energy spikes, or outdated billing models can lead to inflated charges. To maintain cost control and ensure fair allocation, real-time visibility into energy consumption is essential.

Smarter Energy Management with the DOLD RL9405
The DOLD RL9405 Smart Energy Meter, part of the trusted VARIMETER PRO Series, enables precise, real-time monitoring of rack-level energy consumption. Engineered for seamless integration into the tightest server rack spaces, this ultra-compact 35mm-wide meter delivers real-time, precision energy tracking without requiring additional infrastructure. With no complex wiring or downtime, deployment across multiple racks is fast and effortless. The RL9405 ensures fair and precise metering, so businesses pay only for the power they use.
Key benefits include:
• Accurate Cost Allocation – Measure actual energy usage per rack, ensuring fair billing and preventing unexpected power charges.
• Real-Time and Historical Insights – Track energy consumption trends over time to identify inefficiencies and optimise power use.
• Proactive Energy Management – Detect energy spikes or surges that may signal inefficiencies or potential server failures, enabling preventive maintenance and reducing costly downtime.
• Reliable Data Storage – Even during power outages, the RL9405 securely retains energy data, ensuring critical insights are never lost.
• Seamless Remote Monitoring – Modbus TCP/RTU connectivity allows real-time tracking and seamless integration with existing monitoring systems to improve operational efficiency.
• Fast and Effortless Deployment – Compact design allows quick installation in space-constrained environments without downtime.

A Future-Proof Approach to Colocation Energy Management
As energy costs rise and sustainability pressures increase, colocation customers need precise, real-time monitoring to remain cost-efficient and environmentally responsible. The RL9405 ensures that businesses gain full transparency over their energy usage, helping them optimise costs, meet sustainability goals, and avoid unnecessary expenses.
For colocation customers seeking a scalable, reliable energy monitoring solution, the DOLD RL9405 delivers the intelligence needed to take control of power consumption—ensuring that every kilowatt is accounted for.
