The capacitor is often effected by harmonic current ,when compensating capacitive reactive power .Closing the influence of inrush current and operating over-voltage, which can reduce the damage of capacitor and power factor.
This is a new chip again from worldsemi family ,based on WS2812B and WS2813.To solve the chip breakdown and Strip's Voltagedrop ,now we welcome WS2815.The Flex is 30/60/144 Pixel/ LED per meter ,and 5 m in a roll we provide black and white color board.
As the name suggests a wall detector detects studs behind the surface of a wall. The more advanced scanners have multiple modes that detect studs, metal, live AC wiring, non-ferrous metal (such as copper pipe) and ferrous metal (such as rebar).
