Here is a simple and powerful LED circuit that can be operated directly from the AC 100 volt to AC 230 Volts mains supply. The circuit can be used as mains power locator or night lamp etc.. The ...
Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...
Let me introduce an improved version of a blackout alert beeper, which is, in fact, a low-cost mains failure alarm designed to help protect stock and equipment. This device, extremely useful when you ...
Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents when load faults occur. Most readers are probably familiar with two-terminal current-limiting ...
Industrial automation customers can improve their short-circuit protection with a new line of current-limiting, molded-case circuit breakers from Rockwell Automation. The line expands the ...
As electronics have moved lower in voltage, it’s perhaps less common to work on live-mains equipment. Thus particularly among younger hardware hackers it sometimes seems as though such work is viewed ...
Designed and dual-rated for AC and DC applications, the Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer protection for application with up to ...
The circuit protection market is filled with such a wide variety of fuses today that the previously accepted method of specifying fuses is just not enough. Instead, the proper application of fuses in ...
Littelfuse claims that its CPC1561B Solid State Relay (SSR) is the highest current (1 A, 60 V) normally-open SSR currently available on the market to integrate both current limiting and thermal ...
