Feature:
This product is an energized coil production kit, the circuit is simple and reliable, with professional line drawings, convenient for electronic research enthusiasts
Usage:
high school scientific experiment, electronic equipment, negative ion generator, scientific small production. The circuit generates a stable high-frequency arc, high temperature resistance, combustible and ignite combustible materials, so it is called a plasma lighter
Parameter:
Approximate dimensions of 15KV transformer: 27×16×21mm
Input voltage: DC 3.7V-4.2V (limited to 12V, easy to damage is not recommended, this transformer is equally suitable for 12V input voltage, but the base of the feedback resistance should be increased to about 150Ω ~ 1.5KΩ, and the resistor must replace major minor adjustments, or burnt transistors or transformers)
Input current: <2A
Output voltage: about 15KV (pay attention to the safety when using)
Output current: ≤ 0.4A
High voltage bipolar ignition distance: ≤ 0.5cm
When the input of the product is connected to a 3.7V-4.2V power supply, the secondary high voltage output is not connected to high voltage rectifier diodes and capacitors, and the output level is less than 1.5cm long to produce a purple high temperature arc without cracks, but the temperature is very high. Easily and quickly ignite cigarette paper, and even very thin wires burn sparks (like junior high school chemistry experiment thin wires in the oxygen site, but not as intense as oxygen).
Transformer structure:
There are two primary windings, the primary winding, the feedback winding, and the secondary output high voltage. Others: The 15KV transformer is designed for maximum output, and the limit output cannot exceed 15KV, which is one centimeter arc. Higher output voltage can damage the transformer.Circuit board size: 4.2CM * 3.2CM * 0.16CM;
Installation Notes:
1). With the better production of PCB board components, in that the transformer line is thick and thin, it should be noted that other components are online through the screen printing symbols and welding parameters of the board. The transformer board has three pads. The center of the pad hole is relatively large. At the same time, solder a thick enamel wire and a thin enamel wire hole. Not the same side of the thick enameled wire and the fine enameled wire, such as the thick wire on the left and the right. The thin line on the side enters or is welded to the right of the thin line and the thick line to the left. In short, not the thick and thin lines on the same side.
2). To prevent the output 2 wires from being too far away and leaving no load, the 3P pin can be soldered onto the output.
3). After the production is successful, if the output is connected to a voltage double circuit composed of a high-voltage capacitor and three high-voltage rectifiers, DC high voltage can be generated, and an anion generator can be used.
