Transistor BT33 Desk Lamp Dimmable Circuit Kit Electronic Production DIY Kit Circuit Board Manual Training

Description: BT33 lamp dimming kit adopts dimming switch kit composed of single-junction transistor BT33 and unidirectional thyristor McR100-6. Dimming circuit can make the voltage at both ends of the bulb change in the range of dozens of volts to 200 volts, and the dimming effect is significant.The working principle is simple, easy to understand and grasp, and it is also easy to strengthen the understanding of the working principle of single section transistor in the process of manufacturing and debugging. Note: this circuit is powered by 220V mains power, which can adjust the light of 10-40w incandescent lamp. Please pay attention to safety during installation and debugging, and do not touch the circuit board when switching on the power. Circuit operating voltage: 220V circuit load 10-40w incandescent lamps can not be used energy-saving lamps
