01.10.2021 News

STMicroelectronics’ 800 V 8H Triacs operate at full rated current up to the maximum junction temperature of 150 °C, allowing heatsinks in drives for AC loads to be up to 50% smaller to combine compact dimensions with high reliability...

Circuit checks swamp-cooler water level
Circuit checks «swamp-cooler» water level
01.05.2021 Circuits

A “swamp cooler” is an easy way to obtain effective air conditioning, especially in hot and dry climates, if a water source is readily available. Although most units are very reliable, the storage-reservoir control usually uses a single level-detector component...
