“ALC/ALV Series” IP66 Compliant Small Size AC-DC Power Supplies for LED Devices

TDK-Lambda Corporation (President : Yoshiaki Hirota, Head Office : Nihonbashi, Chuoku, Tokyo), a group company of TDK Corporation, has added new models of 60W, 80W and 100W types (total 12 models in 6 types) to the ALC/ALV series of IP66 compliant small size AC-DC switching power supply for LED devices. Order taking will commence on July 20, 2011.

The ALC/ALV product family consists of switching power supplies of constant current type and constant voltage type. The constant current type named the ALC series comes with 6 models (60W, 80W and 100W) and the constant voltage type named the ALV series also comes with 6 models (60W, 80W and 100W). They also give sufficient consideration to safety concerns through compliance with the requirements of the PSE standards (Japanese Electrical Appliance and Material Safety Law). The ALC/ALV product family will be marketed for LED device applications under the brand of TDK-Lambda.

In the efforts of recent years toward realization of low-carbon society, LEDs are very much counted upon as the next generation light source and their market is growing more than ever. With the rapid shift from conventional lighting sources to LED lighting sources, LED devices are getting used in a wider range of applications. Today, even high capacity type lighting equipment and large sign boards use LED solutions. As a consequence, power supplies for LED devices are expected to deliver much more power. So our product family had to be expanded to meet these market requirements.

In order to meet these diversified requirements, we have added 12 models to the “ALC series” of constant current power supplies and the “ALV series” of constant voltage power supplies. With these additional models, the range of users' choices of power supplies for their specific applications has expanded. As for applications under severe environmental conditions that require dust repellent and splash proof characteristics, they give consideration to environmental resistance through compliance with the requirements of the IP66 standards thus they offer users greater flexibility in product design. In addition, the ALC/ALV series products offer operating ambient temperature range between -30ºC and +70ºC thus they can be easily installed in hermetically closed sign boards and equipment.

Furthermore, they are compliant with the IEC61000-3-2 Class C standards (harmonics standards for lighting equipment). As for safety standards, they are compliant with the PSE standards (Japanese Electrical Appliance and Material Safety Law) for the Japanese market, the UL 8750 standards (US standards for safety of LED equipment for use in lighting equipment), the EN61347-1 standards (European safety requirements for lamp control-gear), the EN61347-2-13 standards (European safety requirements for electronic control-gear for LED modules), the CE marking, etc., thus they meet a wide range of customer requirements. We will continue to expand the ALC/ALV product family as our flagship power supplies for LED devices for the growing LED market.

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.
