BT33 MCR100-6 Transistor Desk Lamp Dimmer Circuit Electronic Hobby Kits DIY Circuit Board Electronic Components Kit
Product Description
Reminder: This product is a set of spare parts, you need to assemble it by yourself! BT33 desk lamp dimming kit uses a dimmer switch kit composed of a single junction transistor BT33 and a one-way thyristor MCR100-6. The dimming circuit can make the voltage at both ends of the bulb In the range of tens of volts to 200 volts, the dimming effect is significant. The working principle is simple, easy to understand and master, and it is also convenient to strengthen the understanding of the working principle of single-cell transistors during the production and debugging process.

Note

This circuit uses 220V mains power supply, which can dimming 10-40W incandescent lamps. Pay attention to the installation and debugging process, and do not touch the circuit board when the power is turned on. The working voltage of the circuit: 220V circuit load 10-40W incandescent lamp can not use energy-saving lamps.
