Страховочная лампа. Применение лампы накаливания при ремонте и диагностике импульсных блоков питания

The video, while a bit chaotic, still tries to explain as fully as possible the purpose of safety lamps when repairing and diagnosing switching power supplies. First, I explain the design of my device from the video about repairing simple UPS (switched-mode power supplies), although this is purely my own solution, not cheap :), but I find it more convenient. Then I explain the operating principle using a diagram. And finally, I show how to calculate the lamp power for this connection and how it all works. If you like my multimeter from this video, you can buy it here: http://ali.pub/54es2i , it's a great multimeter. A video about it was on my shopping channel "Kuplyaka":    • Супер мультиметр Aneng 113D   Safety lamp for short-circuit protection. Using an incandescent lamp in power supply repair and diagnostics
