These fuel cells overcome the drawbacks Isolated/Single/Dual Outputs of dry cells, lithium-ion cells, and direct methanol High Reliability fuel cells, significantly reducing weight and increas- Greater than 1,000,000 hrs. ing output power while providing a higher level of Mil Hbk 217F safety, making it possible to provide power in places • where AC power is not available or cannot be used. Military Upgrades By succeeded in solidifying calcium hydride in a sheet configuration using proprietary technologies, Rohm Expanded operating temperature and Aquafairy have been able to generate approximately 4.5 liters of hydrogen -55º to +85º C, no derating required from a sheet less than 3cc in volume (measuring 38x38x2mm), providing a power • output of 5Whr. The hydrogen fuel cells are compact and can operate at ambient Environmental Screening temperatures, making them suitable for use in smartphone chargers, tablet PCs, Selected Screening, Mil Std 883 as power sources outdoors and in remote areas, and in emergency backup power • supplies. In addition, they emit no carbon dioxide or hazardous gases and can be ULTRA Miniature disposed of as general waste. From 0.5" x 0.5" x 0.2" Rohm Semiconductor • www.rohm.com/eu Surface Mount/Thru-Hole • Custom Models Wireless power and dimming controls for OEM lighting • US Manufactured • AS 9100 Approved Phihong USA has developed a new series of remote access tools that provide us- ers with greater control over their LED lighting installations. Compliant with indoor, High Reliability AC/DC outdoor and architectural lighting installations, the new remote access tools allow Power Supplies, Transformers administrators to power, dim, shut off, program and Inductors and reset networked lighting applications from any web-enabled computer, PDA or tablet. Phihong’s customized drivers feature a new on-board module that can seamlessly receive and relay commands via wireless access points (WAPs). Phihong has also developed its own wireless access point, which operates on 802.11b and 802.11g bandwidths at 2.4GHz. Featuring enhanced 802.11i security on the data transfer, the WAP is equipped with standard WEP64/128, TKIP (WAP-PSK) and AES (WPA2-PSK) encryp- tion. Powered by a 5VDC micro USB port, the WAP also meets worldwide electrical and radio standards and is compatible with networks in North America, Europe, Asia, Australia and New Zealand, among others.
