Janitza launches UMG 801 power analyser

Modern data centres often face a choice between designing electrical monitoring systems far beyond immediate needs or replacing equipment as sites expand. Janitza, a German manufacturer of energy measurement and power quality monitoring equipment, says its UMG 801 power analyser is designed to avoid this issue by allowing users to increase capacity from eight to 92 current measuring channels without taking systems offline. The analyser is suited to compact switchboards, with a fully expanded installation occupying less DIN rail space than traditional designs that rely on transformer disconnect terminals. Each add-on module introduces eight additional measuring channels within a single sub-unit, reducing physical footprint within crowded cabinets. Expandable monitoring with fewer installation constraints The core UMG 801 unit supports ten virtual module slots that can be populated in any mix. These include conventional transformer modules, low-power modules, and digital input modules. Bridge modules allow measurement points to be located up to 100 metres away without consuming module capacity, reducing wiring impact and installation complexity. Sampling voltage at 51.2 kHz, the analyser provides Class 0.2 accuracy across voltage, current, and energy readings. This level of precision is used in applications such as calculating power usage effectiveness (PUE) to two decimal places, as well as assessing harmonic distortion that may affect uninterruptible power supplies (UPS). Voltage harmonic analysis extends to the 127th order, and transient events down to 18 microseconds can be recorded. Onboard memory of 4 GB also ensures data continuity during network disruptions. The system is compatible with ISO 50001 energy management frameworks and includes two ethernet interfaces that can operate simultaneously to provide redundant communication paths. Native OPC UA and Modbus TCP/IP support enable direct communication with energy management platforms and legacy supervisory control systems, while whitelisting functions restrict access to approved devices. RS-485 additionally provides further support for older infrastructure. Configuration is carried out through an integrated web server rather than proprietary software, and an optional remote display allows monitoring without opening energised cabinets. Installations typically start with a single base unit at the primary distribution level, with additional modules added gradually as demand grows, reducing the need for upfront expenditure and avoiding replacement activity that risks downtime. Janitza’s remote display connects via USB and mirrors the analyser’s interface, providing visibility of all measurement channels from the switchboard front panel. Physical push controls enable parameter navigation, helping users access configuration and measurement information without opening the enclosure. The company notes that carrying out upgrades without interrupting operations may support facilities that cannot accommodate downtime windows. For more from Janitza, cick here.

Southco develops blind-mate mechanism for liquid cooling

Southco, a US manufacturer of engineered access hardware including latches, hinges, and fasteners, has developed a high-tolerance blind-mate floating mechanism designed for next-generation liquid-cooled data centres. The company says the design is intended to address mechanical tolerance challenges that affect cooling system efficiency and operational stability. It notes that demand for liquid cooling is increasing as traditional air-cooling methods struggle to manage higher power densities associated with AI workloads and high-performance computing. Adoption is accelerating further as operators pursue sustainability and targeted PUE reductions. Liquid cooling, however, requires reliable physical connections, with Southco highlighting that even small alignment deviations at manifold and cold-plate interfaces can disrupt coolant flow, increase pump energy consumption, and heighten the risk of leaks. Managing mechanical deviation in liquid cooling systems Citing guidance in the Open Compute Project’s rack-mounted manifold requirements, Southco notes that a 1mm deviation can raise flow resistance by 15%, leading to around a 7% increase in pump energy. In large facilities, these effects scale alongside thousands of connection points. The company identifies several contributors to misalignment in operational environments: • Accumulated tolerances between rack formats, including EIA-310-D and ORV3, which may reach ±3.2mm • Displacement caused by vibration during transport and operation • Thermal expansion of materials, including copper manifolds expanding more than 1mm over typical temperature ranges Rigid, low-tolerance couplings can leave systems vulnerable to leaks, rising operational costs, and downtime risk, and the newly introduced blind-mate floating mechanism is designed to absorb movement and compensate for these deviations. The product offers floating tolerance of ±4mm radially, axial displacement absorption up to 6mm, and automatic self-centring when disconnected. The design is intended to support long-term leak prevention and meet standards applicable to OCP and ORV3 liquid cooling deployments. Southco adds that the mechanism includes sealing rated to withstand high-pressure testing in line with ASME B31.3 requirements and is intended to support more than ten years of continuous operation. It uses universal quick-disconnect interfaces to enable “blind” maintenance without precise alignment or tooling. The company positions the technology as a step towards enabling rapid maintenance, reducing equipment handling time, and lowering the risk of service interruption. It also points to reduced energy used by pumps through lower flow resistance. Southco sees future development in integrating sensing for temperature, flow, and pressure; exploring lighter materials; and working towards greater standardisation across suppliers and data centre ecosystems.
