Product Description
Resistor Chip ArraysProduct name: Music rotating LED three-dimensional Christmas tree kitWorking voltage: DC 5V (5.5*2.1mm DC power socket)Product model: TJ-56-499Base size: 61 * 61mmMain body size: 128 * 61mmNote: The product is DIY loose parts, the buyer needs to solderit themselves(any questions feel free to contact our customer service)!!!Product IntroductionDC 5V, powered by DC5 power socket, positive inside and negative outside. The circuit is mainly composed of wireless power supply board, wireless reception board and two Christmas tree circuit boards. The wireless power supply part is mainly composed of a NE555 oscillation circuit to output a square wave signal of about 50 kHz to drive the field effect transistor IRF530. The primary coil, the secondary coil on the receiving board and the magnetic ring form a switch transformer. The primary coil is controlled by a field-effect tube to generate a high-speed alternating magnetic field, so that the secondary coil can sense alternating current, which is supplied to the three-dimensional Christmas tree after full-wave rectification.==========Hign-concerned Chemical : NoneType : Voltage RegulatorOrigin : Mainland China
