LED Assembly Strips Offer Backlighting for Kiosks

Pacer has announced the availability of a range of three-LED assembly strips, developed by TT Electronics Optek Technology, for cost-effective backlighting in kiosks and counters. The OPA775/OPA776 Jacob's Ladder LED strips are tightly binned to produce consistent light and are pre-wired with an easy-to-install IDC connector interface. They are suitable for applications such as ATMs, accent lighting, under-counter lighting, media illumination and large channel letter lighting.

The OPA775 series strips are three-LED assemblies; from one to 30 strips can be connected per bus. Designed for operation at 12VDC, each assembly consists of a 7.5in FR-4 board with Zierick 1286T connectors, enabling the construction of the Jacob's Ladder. Each assembly exhibits a luminous flux of 50 lumens and 125mA drive current, so the total current drawn by 30 strips is 3.75A. The OPA776 series strips are six-LED assemblies; from two to 60 strips can be connected per bus. Designed to operate at 24VDC, each assembly has a luminous flux of 100 lumens, and a drive current of 125mA per strip.

One OPA776 series assembly consists of two strips of 7.5in FR-4 board with three LEDs per strip connected by a jumper wire. The total current drawn by 60 strips is 3.75A. Additional technologies available from Pacer to enhance counters and kiosk attractions include: next-generation pyrodetectors, which can sense the approach of the user to enable a dynamic response; light sensors, which monitor the ambient light levels and control the display brightness and light output for optimum effect while conserving energy; and colour sensors, which provide closed-loop feedback enabling colour point maintenance control.

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.
