Powerful Innovations:
Powering the Critical IT Edge
Live Webcast: Thursday, April 16,
11 a.m. - 12 p.m. ET


The dynamics surrounding distributed computing systems which reside on the edge of a network are creating challenges. Housed in smaller spaces, outside of a central data center, these application hubs continue to expand in quantity and criticality. The result is that IT professionals are faced with a new set of demands for providing proper power and support.

Join Kyle Keeper, Director of AC Power Product Management, who will explore 4 primary elements that need to be addressed to effectively power critical, distributed network IT. You will save time, money and reduced headaches … all while driving improved reliability. Join us to discuss:
  • Where and what edge of the network systems should be evaluated.
  • How to recognize network IT edge problems before they escalate.
  • Best practices for managing and deploying power.
  • New technologies and services to save time, money and headaches.

Speaker:

Kyle Keeper
Director, AC Power Product Management

Who should attend?
Managers responsible for:

  • Network/server closets
  • Telecom rooms
  • Back-office systems
  • Small data rooms
  • Branch offices with IT

ECO-Friendly Choice in Single Phase UPS

by Miguel Rascon on 3/26/15 2:46 PM

ECOblog

“Environmental protection”, “high efficiency” and “energy savings” are topics of very high concern for both large corporations, as well as for individuals since these aspects are part of everyday life and may generate significant cost savings in both cases.

This is also valid for UPS ranging from large ones protecting substantially vast datacenters, to small ones with just a few kilowatts that safeguard a network or single cabinet in more modest settings.

The ECO mode – also known as energy saving mode or high efficiency mode depending on the UPS manufacturer – is currently highly discussed within the industry. The debate primarily focuses on on-line UPS and on large UPS. Nevertheless, energy savings and efficiency are extremely important aspects also in small and micro power UPS (typically from 500 VA to 10 kVA). The reasons are the same as for large power systems: savings on energy costs and lower environmental footprint.

Choosing a UPS in the most proper way, means considering the criticality of the application that needs to be protected, as well as evaluating the energy used by the UPS to protect the load against disturbances and interruptions.

Here I would like to highlight the “inherent ECO mode” that can be found in line interactive UPS products (VI or Voltage Independent according to EN 62040-3).

In this type of line interactive UPS (VI), the power stream flows from the input through several protection devices (overcurrent, overvoltage, etc.) and mainly through an Automatic Voltage Regulation (AVR) transformer.

The AVR is in charge of providing output voltage regulation, in order to minimize voltage variations in AC supply and ensure a regulated voltage according to the load tolerances.

Because of the high efficiency of the AVR (typically around 98% or 99%) and of the protection devices through which energy flows, as well as the lower quantity of electronic components used in this type of UPS topology, a high performance line interactive UPS can provide an efficiency level higher than 96% at full load. A perfect example of this is Liebert PSI UPS, which makes use of line interactive technology and therefore of AVR, and which can reach the efficiency levels mentioned above. As said, this operation mode is inherent to line interactive UPS topology, and its high efficiency is also ensured in wide load operating conditions and AC mains variation. While ECO mode in on-line UPS is operating in a smaller input voltage range, line interactive topology is able to operate in high efficiency mode during most input voltage changes while still being capable to provide some output regulation.

When comparing a line interactive UPS with a double conversion online UPS there are many aspects to be taken into consideration such as stepwise or pure sine wave inverter, transfer time, size, etc. However one of the main differences is exactly that line interactive UPS feature “inherent high efficiency” because of the VI technology and the use of AVR as mentioned earlier.

The energy savings associated to it are highly appreciated even if we are talking about single phase UPS meaning UPS which range from 0 to 10 kVA, because:

1. Daily saving  just  a  few  watts  in  continuous UPS operation 365 days a year amounts to a significant total yearly saving

2. In applications such as campuses or big corporations where many of these small UPS devices are used contemporarily, the few watts saved daily per each device increase even more the daily and yearly total saving and reduce the total campus or corporation expenditure.

To provide an example, assume a load of 2.5 kW being protected by a UPS. Such load may correspond to a cabinet with several servers for enterprise applications or to a wiring closet distribution panel. Such UPS can work in line interactive mode (assuming 97% efficiency) or operate in double conversion mode with 90% efficiency, using a rough estimation. The difference in power losses and thus energy savings, will be around 200 W. Assuming an electricity cost of 0.138 €/KWh and doing a quick calculation on yearly savings, you can get a value of around 272 € saved per year. This amount can be multiplied for five years and the total saving will reach nearly 1,500 €.

So it will be clear by now that additional to traditional ECO mode (typically used in double conversion online UPS in general and large UPS in particular) there is an inherent ECO mode used in single phase UPS, specifically line interactive ones.

This grants significant savings to customers as the line interactive technology is inherently highly efficient and as the UPS making use of it are typically used daily all year long so in the long term even little daily saving amounts to a considerable total figure.

And what about ECO modes in on-line UPS in this small UPS range? Is there any difference or advantage? There is an interesting story too.

Use Of DC Distribution Networks Is On The Rise

by Mike Rinaldi on 6/26/13 8:21 AM

The total worldwide capacity of direct current (DC) distribution networks will surpass 2.3 GW by 2025, up from just 196 MW in 2013, according to a new report from Navigant Research.

The report says electricity loads being served by today's alternating current (AC) power grids are increasingly natively DC at the end-use level. In fact, according to some estimates, approximately 80% of the power loads in commercial and residential structures are now DC.

DVL Shines The Spotlight On Data Center For Using “Less Watts"

by Mike Rinaldi on 5/31/13 8:55 AM

-- Award recognizes Conde Nast / CBRE for significantly reducing energy consumption. -- 

cbre conde nast

Bristol, PA – May 29, 2013 –DVL Group, a provider of data center infrastructure management solutions, partnered with 12 data centers to help them save at least 1,000,000 watts of electrical energy.

DVL has officially announced a fourth organization that saved the most watts, which earns them the prestigious Less Watts Award.

The winner of the large category, encompassing data centers greater than 5,000 sq. ft., is Conde Nast / CBRE.  CONGRATULATIONS!!

In addition to honoring the winner with the Less Watts Award, DVL is also making a donation of $1,000 in Conde Nast / CBRE's name to the Delaware Valley Green Building Council (DVGBC).

“The Less Watts competition has been a blast,” says DVL Chief Executive Officer Mike Beck.  “Everyone who participated was incredibly cooperative, enthusiastic and just really great to work with.
