Fujikura has today launched a range of optical fibre cleavers and added the IPA2 fibre alignment method to its existing FSM-100 fibre splicer series. The cleavers, called CT-105+ (right) “feature a new clamping function which improves cleave angles by automatically detecting the optimal camping force. Alongside a 75% reduction in clamp force, there’s a 90% ...

Researchers at Cornell University have taken a step closer towards viable aluminium batteries – that might, for example, one day be used in grid-scale storage. Aluminium is more plentiful and cheaper that lithium, making it potentially attractive for large-scale energy storage even if the technology never became light enough for automotive or phone use. Aluminium ...

XP Power has announced a range of low profile half-brick fan-less ac-dc power supplies which require no external circuitry for operation or EMC compliance. Cooling in the series, dubbed ASB75, can deliver up to 75W and are baseplate cooled – across a baseplate range of -40 to +85°C. Conversion to convection or forced-air cooling, with de-rating above ...

Canadian researchers have used mobile phone data to reveal how much out-of-home travel (dubbed ‘mobility’) is needed to cause a surge in Covid-19 cases. The team uses almost a year’s anonymised phone data (March 2020 to March 2021) to estimate on average how long people were moving outside their homes in Canada, and also noted ...

Delta has launched a second generation of its three-phase 140kVA M125HV photovoltaic string inverter for solar farms, cutting nuisance sound compared with Gen 1. The integrated design combines string fuses, surge protection and dc switching in a single unit within an IP65-rated aluminium enclosure. “Gen2 offers the same maximum output of its predecessor, but now operates ...

STMicroelectronics has introduced a synchronous step-down regulator rated to deliver up to 1.5A with 90% typical efficiency at full load. Called L6981, it works from inputs across 3.5V to 38V, and across -40 to 125°C, suiting the converter to industrial applications. Using a pair of resistors, output voltage can be adjusted from 85omV up to the input-voltage. ...
