California Micro Expands Luxguard Turnkey Range

California Micro Devices has introduced the latest products in the Luxguard range of turnkey solutions. These solutions are suitable for the electrostatic discharge (ESD) protection and thermal management of high-power, high-brightness light-emitting-diode (HBLED) lighting applications. The new Luxguard CM1753 and CM1754 products feature a 50V breakdown voltage specification and deliver an 8kV human-body model (HBM) of ESD protection with low input capacitance for high-power HBLED lighting applications.

Designed as silicon-based side-mount ESD protectors, the CM1753 is designed for P-up common cathode configurations and the CM1754 provides identical protection for N-up common anode configurations. A tiny form factor enables the devices to be used in existing HBLED lamp modules, with the number of LEDs in the string ranging from one to 15. Luxguard products for HBLEDs include silicon submounts and side-mount TVS diodes.

Luxguard submounts provide integrated ESD protection at levels exceeding 15kV HBM. The submount also helps to cushion the LED from stress as a result of thermal expansion coefficient differences between the LED and the lead frame, while the option of an aluminium top coat provides improved reflectivity. CMD also offers TVS diodes mounted next to the LED die within the LED fixture.

ESD ratings vary based on die size and are typically between 8kV and 30kV HBM. The Luxguard CM1753 and CM1754 devices are offered in a die form and can be integrated into existing or new HBLED lamp modules. Samples are available now for the CM1753 and theCM1754, with full production in the second quarter of 2010.

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.
