“HFE1600/2500 Series” Small Size and High Efficiency Front End Power Supplies

TDK-Lambda Corporation (President : Yoshiaki Hirota, Head Office : Nihonbashi, Chuoku, Tokyo), a group company of TDK Corporation, has developed the HFE1600/2500 series of small size and high efficiency front-end switching power supply. Order taking will commence on July 20, 2011.

The HFE1600/2500 series is a small size and high efficiency front-end power supply that can be installed in a 19" rack (1U height). It comes with 2 types (1600W and 2500W) each of which consists of 3 models (12V, 24V and 48V). The HFE1600/2500 series will be marketed for the industrial equipment and data communications markets under the brand of TDK-Lambda.

With the trend of ICs toward low voltage and high current, the power supply layout scheme in industrial equipment has changed in recent years. Method of supplying power is shifting from conventional centralized power system to distributed power system. A distributed system is composed of a front-end power unit and a back-end power unit. A front-end power unit needs to be of small, high efficiency and high capacity type.

In order to meet such requirements, we have developed the HFE 1600/2500 series of small size and high efficiency front-end power supplies. With the new series, the range of users' choices of power supplies for their specific applications has expanded. It features top class power density in the industry (improvement by more than 100% as compared with our previous models) and its compact size makes contributions to customers' requirement of reducing mounting space. It also features high power conversion efficiency of 92% (80 PLUS Gold level) for 1600W 48V output model and 93% (80 PLUS Platinum level) for 2500W 48V output model. Thus, it makes contributions to efforts toward realization of low-carbon society.

In addition, we make available (at option) a 19" shelf rack (1U height) to make construction of a high capacity power system easier. 5 units of HFE1600 or 4 units of HFE2500 can be installed in a single rack and 2 sets of racks can be connected in parallel to build a high capacity power system: 10 units of HFE1600: 15.2 kW (1600Ｗx10x95％) or 8 units of HFE2500: 19 kW (2500Ｗx8x95％). Furthermore, in order to meet a wide range of customer requirements, we have made optionally available a special model (/S type) equipped with the PMBus that can be controlled by external devices.

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.
