The Green Grid Consortium Addresses Energy Efficiency in Data Centers

Monday, February 26th, 2007

Today, February 26, 2007 – The Green Grid consortium announced the completion of its formation, membership structure, technical charter, and made available three white papers.

The consortium also announced its Board of Directors, comprised of AMD, APC, Dell, HP, IBM, Intel, Microsoft, Rackable Systems, SprayCool, Sun Microsystems, and VMware.

Who seems to be missing at this time from the Green Grid consortium:

- Google, who presented a white paper in September 2006, “High-efficiency power supplies for home computers and servers”.
- Power supplies manufacturers, such as Delta, Astec/Artesyn, Lite On, etc. should be also interested in joining the efforts to reduce energy losses.
- 80PLUS organization that did a very good job in promoting highly efficient power supplies.

New Inductor Technology

Friday, February 23rd, 2007

West Coast Magnetics is pleased announce a new inductor technology which achieves a major improvement in cost and efficiency over existing inductor technology. This new technology combines the low DC resistance of a foil wound inductor with the low AC resistance of a litz wire wound inductor. For high current, high ripple applications at frequencies of 10 kHz and up loss reductions in the range of 25% to 50% compared to conventional wire wound devices are typical. The technology fits very well with the newer classes of silicon devices such as IGBTs designed to operate at current levels of 100 amps and up and at frequencies over 10 Khz.

The technology was patented by the Thayer School of Engineering at Dartmouth College and is under exclusive license by West Coast Magnetics. West Coast Magnetics has worked closely with Dartmouth to develop the technology so that it is ready for commercial use.

Weyman Lundquist, President of West Coast Magnetics, summarized the benefits

“Very simply, this new technology, will lead to the use of smaller and lower cost inductors for a host of very important developing power electronic applications in the energy field. Wind energy, hybrid vehicles, solar energy and many other environmentally friendly energy technologies rely on continued improvements in power electronics, and power inductors are one of the main building blocks of virtually all power electronic equipment.”

West Coast Magnetics has completed a market forecast which concludes that the global market for inductors of the class which stand to benefit from this new technology is forecasted to exceed $1 billion by 2010, and reach $2.5 billion by 2015. The breakdown in 2015 is $832 million for hybrid vehicles (including heavy commercial, passenger, and light utility), $812 million for solar, wind and other power generation and transmission applications, $464 million for large uninterruptible power supplies, and $359 for other categories.

If the technology is extended into lower power applications such as personal computers, desktop electronic equipment and handheld devices the total global market will exceed $5 billion in 2015.

Magic Power announced SELV-certified 400-watt Medical Grade ATX Power Supply

Wednesday, February 21st, 2007

Sunnyvale, California – February 20, 2007 – Magic Power Technology Inc. introduced the new 400-watt MPM-842P medical grade certified AC-DC power supply. The MPM-842P is an idea power source for a wide variety of medical equipment devices that demand higher operating power.

The MPM-842P is compliant with UL 60601-1 and IEC 60601-1, meets EMI IEC 60601-1-2 Class B, operates over a wide 90 to 264VAC input range, and provide short-circuit, over voltage and thermal protection. This MPM-842P not only has high current on its 12V rail, which is an excellent choice for today’s medical applications with the demand of high operating power but also offers competitive densities without performance deratings from 0 to 50°C.

Other features include active power factor correction (PFC) to meet IEC 61000-3-2 and IEC 61000-3-3 class D harmonic and flicker standard, CE Mark for the European Low Voltage Directive (LVD), isolating the groundings between primary and secondary to meet “Separated Extra Low Voltage (SELV)” standard. Samples for MPM-842P are available now.

Acopian Redundant Power System Mounts on DIN Rail

Thursday, February 15th, 2007

Easton, PA – February 15, 2007 – Acopian modular linear power systems eliminate the hassle associated with combining power supply outputs for redundancy; all you need to do is plug in the two umbilical cables and connect AC input power and the load. Input switches and fuses, ‘output present’ indicators, isolation diodes and failure alarm circuits are included in the system integration module. It and the two power supplies (which are hot-swappable) may be easily mounted to a DIN rail, wall, chassis or cabinet frame.

Input voltage ranges from 105-125 VAC, 50-40 Hz, single phase. Output ratings from 5 to 125 Vdc, to 425 watts. Other redundant output systems are available in rack-and wall-mounting configurations.

Acopian redundant power systems should be used whenever the highest attainable reliability is essential, as in communications, computer systems (data storage in particular), process controls, utility and municipal systems, and security/safety systems.

The supplies are priced from $895 to $1,710 and shipped within 9 days.

Data sheets can be downloaded on the Acopian website:

About Acopian
Acopian has been designing and manufacturing power supplies since 1957. Standard models have outputs from 1V to 30kV, and up to 1200W. Each is shipped within 3 days (larger units ship within 9 days) after receiving an order. If no standard model meets your needs, we can customize a model for you, or design a ‘special’ for your unique requirements. Acopian also manufactures redundant power supplies in three form factors: rack mounting, (some with power supplies that plug in from the front), wall mounting and modular. Redundant power systems come with a full 5-year warranty and are shipped within 9 days.

Pure Sine Wave Inverter Packs 2KVA into Compact 1U Rackmount Design

Tuesday, February 13th, 2007

February 13, 2007 – Ashland, MA – Schaefer, Inc’s line of pure sine wave inverter products now boast the only 2KVA product in the market that is packaged in a slim, 1U rackmount design. Highly efficient and reliable, the pure sine wave output of the AEP-A2000R Series offers benefits over modified or quasi-sine wave units by delivering “clean” output power for powering sensitive loads and for improving AC equipment performance.

The AEP-A2000R Series is available in three standard input configurations of 12VDC, 24VDC and 48VDC. Outputs are available in 115 or 230VAC (50/60Hz) versions, which are regulated to +/-3% or better. A built-in, 4-6ms automatic bypass switch allows for redundant operation from utility power if the DC supply drops out.

All models in the AEP-A2000R Series feature comprehensive circuit and overload protection with easy to read, user-friendly digital displays and alarms to indicate low input voltage, short circuit, input overvoltage, over temperature, overload and low battery. The display also indicates voltage, amperage, power and temperature. Efficiency is 86 – 92%, depending upon the model selected. The extended operating temperature of -30?C to +60?C allows for installation in even the most extreme environments. EMI is minimized for reduced impact on other sensitive equipment.

The compact, 1U, rackmount design is rugged and ideal for industrial, utility, satellite, military, computer, communications, emergency vehicle, marine, and general backup power applications. The slim size of 16″ x 19″ x 1.73″ (d x w x h) fits easily into 1U racks.

Schaefer’s full family of pure sine wave inverters also includes stand alone modules starting at 700W of power, along with higher power 3-in-1 units that include a UPS and battery charger. Modifications to standard units are available. In addition, Schaefer can design and manufacture fully custom solutions.

AEP-A2000R pricing is from $1062.00 at 100 pieces, with significant OEM quantity discounts. Delivery is stock to 8 weeks ARO.
