Onsite Power - Products & Services ReliOn has released its new E-2500 fuel cell system. The E-2500 is the third in a new ReliOn product line, the E-series. The E-2500 fuel cell system offers 2,500 Watts of power in a chassis that is sixty percent of the size of ReliOn’s T-2000 2,000 Watt product. The development of this product utilizes the patented modular, fault-tolerant aspects of ReliOn’s fuel cell systems in higher density power modules. Emissions are limited to warm air and a small amount of water, and the E-2500 system is exempt from the most stringent air quality standards, such as those set by the California Air Resources Board. A scalable backup power solution, the E-2500 fuel cell system can provide 24 hours of power for equipment needing up to 10 kW in a small footprint. Higher power configurations are available as well. “For customer applications where space is an issue, this addition to our product suite offers a higher density option, while continuing to provide the reliability and scalability our customers have come to expect from ReliOn,” said Joe Blanchard, ReliOn’s vice president, Product Line Management” New ReliOn E-2500 Fuel Cell Product Offers High Reliability in Smaller Package of UPS batteries while they are in service. Sentinel 3+ gives complete confidence that battery arrays will deliver their rated power when called on to do so, and identifies weak and failing cells without the need to remove them from service for cycling tests. Designers of the latest UPS systems have exploited technology developments such as the availability of fast insulated-gate bipolar transistors (IGBTs) to reduce costs by eliminating bulky and expensive transformers from their circuit configurations. The battery packs that the Sentinel product monitors are, in consequence, operated in floating voltage mode; the battery is subjected to higher ripple currents, and the monitoring circuitry must handle high common-mode voltages, with superimposed high-amplitude, fast transients. LEM’s Sentinel 3+ features upgraded algorithms to address this more challenging measurement environment, as well as improved EMC immunity and enhanced overall robustness. Sentinel 3+ delivers voltage measurements over a range of 0.9 to 16 V with an accuracy of +/-0.5 percent; impedance measurement from 0.05 to 250 mΩ with repeatability of +/-2 percent. Sentinel 3+ features Common Mode Transient Immunity up to 20 kV/µsec with a common-mode voltage level of +/-600 V, and a transient repetition rate of 20 kHz. The University of Southern California, the California Institute of Technology, SFC Energy, Inc., and SFC Energy AG have announced the execution of a license to a portfolio of US patents for direct methanol fuel cell technology (DMFC). The nonexclusive license to the universities’ patents will facilitate SFC Energy, Inc.’s expansion of its methanol fuel cell products into the US market. Direct methanol fuel cells hold promise as a clean and efficient technology for generating grid-independent electricity directly from methanol, a liquid fuel that is ubiquitously available. DMFC technology does not require an external fuel reformer, and is an excellent candidate for very small to mid-sized applications. The licensed technology was invented by a USC Loker Hydrocarbon Research Institute team led by G. K. Surya Prakash and Nobel laureate George Olah, and by S. Surampudi, S. R. Narayanan, E. Vamos, H. Frank, and G. Halpert at Caltech/JPL. It includes fundamental patents covering the direct conversion of liquid fuels to electricity by specially designed fuel cells. The universities had previously licensed the patent portfolio to other companies, but those licenses have terminated. SFC Energy, Inc. is the US affiliate of SFC Energy AG. USC, Caltech, and SFC Energy AG are in discussions regarding a license to the patents that the universities hold in countries outside of the US. Direct Methanol Fuel Cell (DMFC) Technology Portfolio Licensed from USC/Caltech by SFC Energy, Inc. Alpha Technologies, Inc. has introduced of the FlexPoint 1207-F (FPR1207-F), a telecommunications grade optical network terminal power supply. The FPR1207-F UPS provides 7 W of 12 Vdc primary and battery standby power for Fiber applications. “The FlexPoint FPR1207-F meets the telecommunication industry’s stringent requirements for uncontrolled environments, while providing an aesthetically pleasing solution for residential installations,” said Jim Heidenreich, vice president of Product Management, Alpha. “Unlike other standby power supplies, it reserves 25 percent battery power, enabling activation for emergency telephone calls in extended power outage situations meaning increased reliability.” The FlexPoint is an environmentally-hardened standby power supply intended to be placed indoor or outdoor in sheltered locations. Its size allows placement in the most densely populated structured medial enclosures and its user interfaces include visual status indicators, audible alarms, a silence alarm button and an auxiliary 12 Vdc power input port allowing additional battery capacity to be added for longer standby runtimes. Alpha Extends FlexPoint Family with the Addition of the FPR1207-F Series LEM has introduced its Sentinel 3+, the latest generation of the Sentinel product that monitors the state of health of batteries in UPS systems. The enhancements incorporated in Sentinel 3+ enable full integration into the newest architectures of UPS, accommodating UPS design evolutions such as transformerless circuit topologies. Sentinel 3+ is a battery-monitoring transducer that measures the voltage, temperature and impedance of cells and complete batteries in UPS installations of all sizes up to mega-watt back-up power supplies. Sentinel 3+ reports its measurements, on valve-regulated lead-acid (VRLA), gel or flooded stationary batteries to supervisory systems over a dedicated communications bus, and offers the capability to assess the state-of-health 24 www.RemoteMagazine.com LEM Releases Sentinel 3+ Battery Monitoring Transducer Upgrade for UPS Designs Nextreme Thermal Solutions has introduced the Thermobility Wireless Power Generator WPG-1S evaluation kit with on-board energy storage using the Infinergy D-MPM101 micro power module from Infinite Power Solutions. The WPG-1S uses solid-state thin-film thermoelectric technology to convert heat into electricity for a variety of self-powered wireless applications. Thermobility uses differences in temperature to enable power anywhere there is an adequate heat source and eliminates the need to use traditional wired power sources or batteries. When paired with wireless transmitters, the Thermobility solution can provide electric power for years of maintenance-free operation, thus expanding the possibilities for new wireless sensor and security applications in industrial control, transportation and building management. The Thermobility WPG-1S uses the Infinergy D-MPM101, a devel- Nextreme Offers Thermobility Wireless Power Generator With Infinergy On-Board Energy Storage http://www.RemoteMagazine.com
