Larson Electronics Releases AC to DC Power Converter with Cigarette Cork Outlet - Business Wire (press release)

The DCP-23CP-12V power converter from Larson Electronics features a mounted 12 volt DC cigarette jam outlet inside a weather proof outlet box. This outlet is then connected to a transformer which includes an industrial grade male pigtail and a foot of cable, allowing operators to connect to common wall outlets to power 12 volt DC equipment. The outlet and converter meeting is mounted to a heavy gauge metal strip with a machined oval opening on one end for easy hanging of the unit from hooks or other opportune locations. This unit provides a safe and effective way for users to tap into and utilize common 120 to 277 volts AC power sources and converts the prevalent to 12 volts DC, allowing users to use standard AC power to operate equipment like our low voltage LED... This transformer features an IP67 rated waterproof design, making it befitting for indoor or outdoor use and is wet area approved. It includes integral short circuit, over voltage, over temperature and overload protection that will stifle the unit down or reduce output in case of faults and overloads to protect the unit and connected equipment from damage. The packed size and wide input voltage range of the unit makes it ideal for indoor and outdoor operation of Larson’s LED descend bars, hand lamps and other equipment that requires 12 volts DC current. “This unit will limit current when an over current shape is encountered and recovers when the condition is no longer a threat, protecting the equipment that is connected to the unit,” said Rob Bresnahan, CEO of Larson Electronics. “It is recommended that you do not excel 75% of the unit’s output amperage in order to obtain the best performance and longest operational life. Larson Electronics specializes in shirt-pocket industrial lighting equipment, high mast light towers, explosion proof light fixtures, power dissemination systems, LED lighting and more.

Dash harvesting from road bumps could save 0.7l/100km, claims Audi - EETE Automotive (registration)

Audi's eROT archetype uses electromechanical rotary dampers instead of the current hydraulic dampers to recharge a battery. The eROT actively controlled postponing adapts to irregularities in the road surface and the driver’s driving style and feeds a high-output 48V electrical system with a 0. 5kWh lithium-ion battery that produces a mountain output of 13 kilowatts. A DC converter connects the 48-volt electrical subsystem to the 12-volt primary electrical system, which includes a capital-efficiency, enhanced output generator. A lever absorbs the motion of the wheel carrier and transmits this force via a series of gears to an galvanizing motor, which converts it into electricity. This generates 100 to 150 watts on average during testing on German roads – from 3 W on a freshly paved motorway to 613 W on a hasty secondary road. The technology needs a 48V power system which is the primary electrical system in a new high-performance mild composite drive in an Audi model in 2017. This will offer potential fuel savings of up to 0. 7 litres per 100 kilometers. The damper can also be software controlled to configure the compression seizure to be comfortably soft without compromising the taut damping of the rebound stroke. Source: www.automotive-eetimes.com

Watts vs. lumens: How to on the right LED light bulb - CNET

If you've dog-tired most of your adult life buying incandescent bulbs, you're probably pretty comfortable choosing a bulb by its watts rating. LED bulbs have come along, though, and introduced the lumens rating. Lumens and watts are remarkable, which can make it harder to figure out what type of bulb to buy. When buying an incandescent bulb, the watts rating gives consumers a esteemed indication of how bright a bulb is. The more watts, the brighter the bulb. An LED that uses 60 watts is in no way comparable to an incandescent bulb that uses 60 watts. In act, a 60-watt LED just may blind you. LEDs are designed to use less energy and naturally have a lower watts rating. This means it's useless to use watts to judge brightness. To fix the problem, bulb companies have started using lumens to rate bulbs. This gives you a more accurate indication of how much light to wait for from an LED. Measuring in lumens isn't a new concept designed just for LEDs. It's a rating that's been used for decades as a measurement of how much light a bulb (or anything else) emits. In 2011, the US Federal Marketing Commission started requiring manufacturers of compact fluorescent, incandescent and LED bulbs to use lumens as an indication of how bright a bulb will be. "While watt measurements are knowledgeable about to consumers and have... "As a result, reliance on watt measurements alone make it difficult for consumers to compare traditional glowing bulbs to more efficient bulbs, such as compact fluorescents. On packaging, the lumen rating is indicated by a number followed by "lm," the abbreviation for lumens. The higher the lumen rating, the brighter the bulb will be. Picking the honesty bulb The easiest way to figure out what bulb you need is by using an incandescent/LED conversion cart. Say you normally use a 60-watt incandescent bulb, for eg. You would probably want to choose an LED bulb that uses 8 to 12 watts and has a lumen rating of 800 to get the same illumination. This conversion graph will help you find an LED bulb similar to the incandescent you've been using:. As you can see, with LEDs, the amount of wattage you'll need varies for each lumen rating. This is because some LED brands have created bulbs that proposal more lumens for less wattage. For the best energy savings, Energy Star recommends that you find a selection of bulbs with the most lumens you for, and then choose one with the lowest wattage. Source: www.cnet.com
