Eaton Among First in Industry to Offer 480/277V Rack Power Distribution Units to Increase Data Center Efficiency

Diversified industrial manufacturer Eaton Corporation today announced 480 volt (V) configurations for its ePDU® power distribution product line. The new units are designed to help achieve efficiency gains in large enterprise data centers where high-density computing is required. Eaton is the first among power distribution solution providers to meet the needs of data centers implementing 480/277V custom hardware.

“We’ve noticed a trend with many of the new, cutting-edge data centers choosing a 480V power scheme and 277V custom power supplies that are extremely efficient,” said Joe Skorjanec, ePDU product manager, Eaton Distributed Power Solutions. “Power distribution units at this voltage are usually only available as custom solutions. Eaton is among the first in the industry to offer 480V as part of our ePDU catalog offering in order to better meet the needs of server manufacturers.”

Eaton is well-known as a full solution provider through its data center hardware and power management software capabilities. The majority of Eaton’s three-phase uninterruptible power supplies, including the Eaton 9355, 9390 and 9395, are designed to work seamlessly with a 480V ePDU solution.

Eaton introduced a new line of 400V ePDU products in March and continues to drive efficiency gains with this new 480/277V AC offering. Since utility power in North America typically enters a facility at 480V AC, Eaton’s 480V ePDU products remove the need for step-down transformers, reduce distribution costs and power high-efficiency 277V power supplies. A server operating at 277V requires 25 percent less current than a server operating at 208V. This allows for a reduction in upstream circuits, which reduces overall copper and power distribution costs.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
