Data centres are adopting high performance computing to support artificial intelligence (AI) and machine learning (ML) programmes. This in turn, is causing a significant rise in chip, server, and rack densities. New environments are being designed specifically for AI workloads, including High Density Suites and PODs.
To support this trend, MPL has developed a range of high resilience RPDU solutions specifically aimed at addressing the needs of the high-power density market. These products are designed to perform in high power, high ambient temperature environments. They are widely deployed in high resilience applications and are fully configurable to meet exact client requirements.
The family of high density 63A and 120A RPDUs feature:
A design aimed specifically for high ambient temperature environments, negating the need for components vulnerable in elevated temperatures (for example LCD displays). This approach increases life expectancy and overall reliability of the RPDU
Built in Residual Current Monitoring (RCM) in real time. This feature is an accepted alternative to isolation for periodic inspection and testing, in accordance with IEC 60364
Enhanced internal wiring methodology / ratings including the use of Ultrasonic welded joints, to ensure the very highest build standards here in the UK
MCBs for enhanced safety and circuit protection
Industry leading locking socket outlet technology
Low smoke, zero halogen (LSOH) power feeds
Scalable intelligence including aggregated and per outlet monitoring combined with individual socket control via bi-state latching relays
Built in environmental functionality
Simplified device discovery.
Design Philosophy
The primary function of any RPDU is to distribute power within the cabinet, effectively and reliably. Any additional features built into the units should not interfere with this primary function.
Therefore, all other features, although important to facilities and operation management, must be designed so as not to compromise resilience or introduce unacceptable operational disruption and downtime.
In today’s Data Centres, there is a driver from equipment manufacturers to increase inlet temperatures (up to 27°C) and there is increasing demand for higher power consumptions and high-density solutions.
This has resulted in elevated equipment exhaust temperatures which in turn, compromises the reliability and rating of the RPDU, by impacting the surrounding ambient temperature where the RPDU is positioned.
Certain components, such as LCD screens, neon indicators and internal power supplies are vulnerable in such high ambient temperatures with resulting reductions in life expectancy and reliability.
With these design considerations in mind, MPL Technology Group has designed its family of RPDUs to offer the highest levels of resilience, by developing an architecture that reduces points of failure and enhances overall reliability by reducing power strip complexity.
Cost Efficient Solution Architecture
The MPL RPDUs are connected and powered via a dedicated ‘plug and play’ communications bus (RS485) and are centrally managed via the data collection Gateways. As a result, the architecture allows for up to 256 devices being managed on a single IP address. This approach reduces the infrastructure complexity and the associated costs. No LCD screen is required at RPDU level to assist with the configuration.
Granular Monitoring
The RPDUs accurately measure (better than ±1%) Volts, Amps, kW, kWh, kVA, Power Factor, Environmental and door access. MID (measuring Instrumentation Directive) versions are also available as a standard offering.
Why focus on Residual Current Monitoring (RCM)
Leakage current to earth is a natural phenomenon in every installation. IEC 60050 refers to the current that flows from a live part or conductor to earth without a fault. However, leakage current can slowly increase due to the ageing of wire insulation (i.e., excessive temperatures caused by harmonics or over currents) or through the degradation in the quality of the earth connection. Fault currents present a real threat of electrocution of personnel or electrical fire.
Continuous Residual Current Monitoring is the only method to detect dangerous fault currents at an early stage, thereby avoiding damage to the power system and the unwanted tripping of RCD’s, whilst eliminating the requirement for insulation resistance testing/mains power disconnection.
Why deploy MID certified product
MID metering tends to be used for sub-billing in Co-Location environments where there is a direct correlation between a meter reading and an invoice.
