It can be inconvenient to replace batteries in electronic devices that need to work for a long period of time, either in biomedical monitoring systems worn by a patient or in monitors for machinery or industrial installations in remote or inaccessible situations.
B&K Precision has introduced the 9150 single-output, linear-regulated DC power supply series with four affordable models providing varying voltage and current levels in the 500 range.
austriamicrosystems has announced the AS8510, a high-precision data acquisition front-end IC for motor vehicle battery current, voltage, temperature sense applications and in general for sensor interface applications where precise measurement of small signals close to ground is required.
Material scientists at the Nano/Bio Interface Centre of the University of Pennsylvania have demonstrated the transduction of optical radiation to electrical current in a molecular circuit.
Australian company Digital Works has made a major breakthrough in the global battery charger market by developing two first-to-market products that leverage USB technology to charge different mobile devices from the one unit as well as standard rechargeable batteries.
‘Baseload’ solar power, once a distant dream, is now claimed to be a reality. While solar electricity was once limited to when the sun was shining, solar thermal energy can now operate 24 hours a day, even at night, with an ingenious and cheap storage method using molten salt.
Monash University researchers are at the forefront of efforts to develop a new generation of solar cells that are lighter, cheaper and able to be embedded in future roofing materials.
Mean Well has released the WDR-120 slim DIN rail power supply series. It joins the 240 and 480 W version of the same series and features a wide input range of 180~550 VAC which can be used in general power systems with single-phase 240 VAC input or can capture one phase from the 415 VAC three-phase system.
Britain’s first nearshore wave energy converter has moved another step closer to generating clean, green energy.
One of the most remarkable and novel discoveries in the last 400 years has been electricity. One may ask, “Has electricity been around that long?” The answer is yes, and perhaps much longer, but the practical use of electricity has only been at our disposal since the mid- to late-1800s and, at first, in a limited way.
The No-Break DC (i) series battery charger has been designed primarily to remotely monitor battery-backed control systems.
North Atlantic Industries (NAI) has released a next-generation, DSP-based intelligent power monitor and control unit. The model iPM monitors single- or 3-phase wye or delta connected power lines for voltage, frequency, phase sequence, THD and DC component. When any of these parameters are outside of their preprogrammed limits, the iPM internal 10 A relay opens and disconnects the power from the load. The device has a universal input voltage range of 80 to 230 RMS and a universal input frequency range of 47 to 800 Hz. It includes a background self-test capability that constantly monitors the health of the unit.
The introduction of integrated voltage regulators was a boon for electronic engineers. Before that, regulated power supplies were rather complex, particularly if such a power supply had to be short-circuit proof.
