Data center monitoring solutions

Server monitoring in banks

In most cases these are installations with limited space for fitting a proper monitoring system. Our solution includes the EM270 and EM280 Quick-fit meters and, where necessary, the TCD1X-2X-3X and TCD06BX-BS current transformers.

Server monitoring in production facilities

In most cases these are retrofit installations, where it is necessary to install a reliable monitoring system to manage a combination of regular loads and servers. The flexibility needed is guaranteed by our EM210 and EM271 meters, combined with CTV/ROG and TCD-xM sensing solutions.

A 94% commissioning time saving

Traditional tap-off box solution: the first configuration, the following addressing and the final commissioning in case of 16 bus-bar trunking systems of 32 tap-off boxes each (total more than 2 hours) is about a total of 34 hours of Professionals work.
ET272 + VMU-C tap-off box solution: no manual configuration, no ID addressing, a general process improvement. Leading to a total configuration and commissioning time reduction from 34 hours of Professionals work to only 2 hours!

Power busbar-based monitoring in Data centers

Electrical installations in big data centers are built according to different guidelines: either bus-bar trunking systems (bus-ducts with tap off boxes) or power distribution units can be used. Carlo Gavazzi has a solution in both cases, with the purpose of dramatically saving set-up time and costs, providing data with the necessary granularity.
In case of existing or new installation based on power bus-bar trunking systems (busduct), the solution is the combination of ET272 quick-fit analyzer combined with the VMUC EM Web-Server/Gateway.

PDU-based monitoring in Data centers

When the electrical system is different from a busbar trunking or busduct system and feeding numerous loads into a common distribution board, the WM50-96 is the ideal solution for branch circuit monitoring. The solution is based on a one core unit, the WM50 which is usually installed and connected to the mains and some TCD12 units as combined meters installed downstream from the MCBs for single phase or three-phase loads. As the whole installation cost is not only made up of the component costs but also the installation and commissioning costs, this innovative solution allows you to achieve more than 75% installation and commissioning savings compared to a regular solution.

Server monitoring in Data centers
Ultra flexible solution for regular PDU-based server systems

WM15, displaying measured variables in both analogue and digital formats and ET340, a metering unit without display are the ideal metering solution for server rooms in Banks, production facilities and Data Centers. This solution provides the following benefits: configuration and commissioning with the same advanced OptoProg and UCS tools saving time and being more effective; all ET340 units can be daisy chained using an RJ45 cable being more reliable in connections and cutting connection costs; a single ET340 has the same footprint of three single-phase MCBs or a three-phase MCB, this means a modularity of three and therefore the capability to be mounted wherever there is a limited space or there is the need to put them in an array of many MCBs; UWP 3.0 being key part of the whole metering system can manage, using a proper RJ45 cable, up to 100 ET340 units equivalent to 300 server or server racks, a massive number of information.

Ultra flexible solution for full DIN-rail based PDUs

If the target is to provide a streamlined solution for server rooms in banks and production facilities, than the solution is EM24 + ET340. Streamlining a monitoring solution for banks and facilities means, to be more cost effective in providing solutions capable to perform not only main and submetering but also being able to gather data from utility meters. For EM24, it doesn’t matter if the pulse signals are coming from watt-hour meters, gas meters, water meters or from all of them, because it has all the necessary hardware resources to manage all those signals. So, if EM24 has the task to perform, in the installation, the integration of the utility meters into the UWP 3.0 monitoring platform, it has in addition, also the task to perform the main metering in the distribution board where it is installed. While the ET340 units have the task to measure a full set of electrical variables being needed to complete the analysis of all loads connected downstream the main MCB or MCCB.

Utility, main and sub meter integration

If utility meters are M-Bus (EN13757) wired or wireless based, then the SIU-MBC can be used as a dual pulse counter or directly via the SIU-MBM which acts as a gateway. These add-on solutions make this valuable information available for your Automatic Energy Monitoring System. More specifically: if the utility meter has only a pulse output, no available auxiliary power supply and the meter itself is far from you nearest distribution board than the solution is the wireless SIU-MBC, it is self-powered by an internal battery lasting up to 12 years, and is perfectly suited to outdoor applications; if the utility meter is wired or wireless M-Bus-based, than the solution is SIU-MBM.

In many installations, old fashioned meters are still working properly but energy information is still collected manually with both high data collection costs and potential transcription errors. Now, concentrating on multiple meters' pulse outputs and making them available as RS485 Modbus counters is possible, thanks to the modular VMU-MC + VMU-OC solution ranging from 2 to 11 pulse inputs (counters). Pulse to Modbus conversion is the key to automatic data collection benefiting from quality data, data granularity and whole data management.

Explore and analyse data

UWP 3.0 is a core unit capable to collect data from meters and other sensing devices suitable to be used to monitor critical loads.
UWP 3.0 is key to meet today's Energy Managers and Energy Service Companies requirements to achieve energy efficiency goals, but also to monitor the behaviour of critical loads such as dry coolers, air cooled chillers and servers in data Centers. It can provide, as a first step, all the remote, on-premise, or cloud functionalities. Simple architecture, short commissioning time, cost reductions, error proof configuration, expandability and scalability are the distinctive characteristics of this unit. UWP 3.0 is a Web-Server but also a gateway. UWP 3.0 is Microsoft® certified for IoT. One or many UWP 3.0 pushing their data to the Microsoft® Azure IoT Hub will allow System Integrators to extend the level of integration to other systems. Data can be shared locally via Modbus/TCP or BACnet, while M2M makes integration with other systems possible via Rest-API or standard FTP, SFTP, FTPS communication. Excel® reports can be generated online or via the embedded scheduler.

MRCD type installation protection devices

To avoid trips in protection and maintain the availability of the power supply, our MRCDs DEA71 and DEB71, combined with the CTG core balance transformer, are our IEC60947-2 compliant solutions for detecting earth leakage currents.
