Revolutionising power monitoring

As data centre infrastructure evolves, power monitoring systems often face a trade off between over specifying capacity and undertaking disruptive upgrades as requirements grow. The UMG 801 modular power analyser from Janitza addresses this challenge by allowing expansion from eight to 92 current measuring channels without system downtime, supporting more flexible capacity planning.

For space-conscious cabinets, the UMG 801 offers a distinct advantage. Fully expanded, this analyser requires around a metre less DIN rail space compared to traditional systems. This reduction is made possible using low-power current transformer modules, which proficiently consolidate measuring tasks into a singular sub-unit.

The core's ten virtual slots readily accommodate Janitza’s versatile plug-and-play modules, be it traditional transformer modules, low-power options, or digital input modules. Bridge modules further simplify connectivity, linking measurement points up to 100 metres apart whilst mitigating installation complexities and delivering up to 40% cost savings compared to conventional designs.

With voltage sampling at 51.2 kHz, the UMG 801 provides Class 0.2 accuracy across various parameters. This precision is crucial for calculating Power Usage Effectiveness (PUE) and identifying distortions that might affect UPS performance. The instrument's 4GB memory ensures uninterrupted data recording even amidst network outages.

Compliant with ISO 50001 standards, the UMG 801 supports robust communication through dual Ethernet interfaces and native OPC UA protocols, enabling seamless data exchanges. A strategic combination of Modbus TCP/IP and legacy RS-485 infrastructure assures backward compatibility, maintaining secure, authorised system access.

The UMG 801 emphasises user-friendly deployment with its integrated web server, eliminating the need for proprietary software. The availability of a remote display option extends functionality by facilitating real-time monitoring and adjustments during active operations.

Commencing with the base unit, typical installations can be progressively expanded as demand grows, eliminating the financial burden of initial over-capacity while avoiding downtime—the latter being particularly vital in environments where downtime is unacceptable.

Augmenting operational ease, the Janitza RD 96 remote display enhances visibility by presenting all measured values directly on the switchboard cabinet, thereby ensuring real-time access without needing to open cabinet doors.

In summary, the Janitza UMG 801 emerges as a scalable, precise, and cost-effective solution ideal for data centres requiring dynamic adaptability and high integration efficiency in a compact footprint.
