POWER SUPLIES Pin-shaped lithium ion battery targets wearable device market Panasonic Corporation has developed a 13 mAh pin shaped lithium ion battery with a diameter of 3.5mm and a weight of 0.6g which makes the device suitable for powering wearable devices. The CG-320 battery claims to be the industry’s smallest cylindrical shaped rechargeable lithium ion battery and features the high reliability and high output required for nearfield communications (NFC). Mass production and shipping are planned to begin in February, 2015 with a monthly production of one hundred thousand units. Panasonic has taken advantage of its battery material technology cultivated with lithium ion batteries used in information and communication equipment applications, and coin-shaped and other small lithium battery production technology, to commercialize the pin shaped battery, which at 3.5 mm is the industry’s smallest pin-shaped lithium ion battery. The rechargeable battery can be used repeatedly and has the output capability required for NFC. A stainless steel can is used for the exterior providing for dimensional stability. Panasonic Corporation http://panasonic.net/ LED power supply meets EMI global lighting standards SL Power Electronics, a division of SL Industries, has introduced the LB115 power supply family intended for architectural LED lighting applications. The power supply series delivers 115 watts in a compact 2 x 4 x 1.2 inch footprint and has a built in EMI filter to meet EN55015 class B requirements for lighting fixtures. The LB115 is a single output internal power supply with a wide temperature that is ideal for low power LED applications – such as stage lighting – requiring an efficient and compact power solution. Perfect for space constrained applications, the LB115 offers a universal input of 90 to 264 Vac and comes in four models with output voltages ranging from 12 to 56V. The LB115 features a convection cooled rating of 75 watts and a maximum air cooled rating of 115 watts with 200 LFM, which is delivered throughout the wide operating temperature range from -20 to 50°C. Featuring active power factor correction, the LB115 starts up at -40°C temperature and can operate safely in elevated temperatures with reduced output loading, providing a -40 to 70°C temperature range for intended applications.
