Wavelength Electronics’ USBKIT bus-powered interface board and software package is easily wired using on-board screw terminals and the QuickConnect™ virtual control panel provides out-of-the-box functionality with strip chart graphs that show real-time laser system status. One laser diode driver and one temperature controller can be simultaneously operated with the USBKIT. … [Read more...]
Converter Family Maximizes Power Supply Efficiency, Minimizes Footprint
Power Integrations introduced HiperLCS, a family of high-voltage LLC power supply ICs that incorporate the controller, high- and low-side drivers, and both MOSFETs into a single low-cost package. Highly integrated HiperLCS ICs offer the flexibility to optimize designs either for high efficiency, with a maximum efficiency of better than 97%, or for size, by leveraging … [Read more...]
Software Protects Water Utilities from Terrorist Attacks and Contaminants
An open-source software developed by Sandia National Laboratories in partnership with the Environmental Protection Agency tells utility operators within minutes whether something is wrong with their water, giving them time to warn and protect the public. And it’s improving water quality by giving utility managers more comprehensive real-time data about changes in their … [Read more...]
Underfloor Electric Heating. Part II – Infrared Thermography
3D simulation can provide a detailed prediction of temperature and heat flux values at 10s of 1000s of points in a 3D model, experimental methods are somewhat limited in terms of the wealth of data they are capable of providing. But hey, this isn't going to degrade into a pitched battle between simulators and experimentalists, nowadays good engineers (should) do both. "No one … [Read more...]
Underfloor Electric Heating. Part I: In by Christmas
It's been over two years since the foundations went in for the extension we're building on our house. In that time I've come to respect and somewhat rely on glib phrases such as "Good things come to those who wait" and "Patience is a virtue". I told my better half we'd be moved in by Christmas, I didn't say which one though. In this blog series of the time I used FloVENT to … [Read more...]
