High-Power LEDs for General Lighting Applications

TME offers the Optoflash range of high-power LED products for use in general-purpose lighting applications such as lamps, ceiling light panels, wall illuminators, floodlights and more. Optoflash products are based on high-power LEDs of manufacturers such as Seoul Semiconductor, Luxeon and Cree. The company also offers single OF series LED 'bulbs' designed to be easily installed in standard downlight housings E27, MR16, GU10 and suitable for typical power supply voltage of 12V or 230V.

The LED bulbs can be used directly in ordinary lamps. TME said a key advantage of Optoflash LED bulbs is their long-lasting efficiency. After 1,000 hours of continuous operation the initial lumen output drops only by a few per cent. A suitable colour temperature can be chosen according to individual needs. Available options include: cool white (5,000-7,000K) and warm white (2,800-3,500K).

The power of the LEDs (from one to more than 10) installed in a bulb ranges from 1W to 4W. An example of a ready-to-use light solution is the OF-BM361xxS12 wall illuminator, which is available in different colours and colour temperatures: cool white, warm white, red, green, blue and yellow. The wall illuminator is equipped with a two-contact connection and may be supplied from 85-250VAC power sources. Its light panel consists of 36 1W high-power LEDs. The wall illuminator is protected by an aluminium housing.

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.
