Zeus: An AC to DC High Watt Power Supply Unit While making a customized RGB LED set up at our home, basically it was a bunch of addressable 5v LEDs the WS2812, but unfortunately, we didn't have a high current power source to light them up properly. Since there was a lot of them, it required around 9 Amps of current to lighten up at full brightness. This led us to design one Power Supply for this purpose, as well… |

Working with High Voltage Electronic Designs? Here is What You Should Know For engineers who spend their design time in the single-digit, low-voltage world, the phrase "high voltage" may conjure up voltages in the double digits, perhaps as high as 24V or 48V DC, or even the triple-digit domain of line voltages of 120/240 VAC. Yet there's a huge and essential world of engineering design that must be done at 1000V, 1500V, and higher voltages… |
