TESLA Loa Mini Không Dây + Pin Q2H7 tại Lotte Market

Giới thiệu TESLA Loa Mini Không Dây + Pin Q2H7 tại Lotte Market

first, the circuit parameters

power supply input voltage: 24v dc;
power supply current: 2a-3a;
power supply interface: positive and negative within 5.5-2.1;
audio interface: 3.5 audio port;
product size: length 8.5cm x width 8.5cm x height 20cm;
secondary coil size: diameter 4cm height 10cm or so;
number of coil turns: 370 turns, the enameled wire with a coil diameter of 0.2, we are winding when the coil is shipped;
the finished product weight is about 190 grams;


please note that when using the power, first turn on the 220v to 24v switching power supply, after a delay of 1-2 seconds, then turn on the tesla power switch after the power supply voltage is stable. when the power is off, first turn off the tesla switch, then turn off the 220v to 24v switching power supply. this is because the switching power supply generally has a slow start function, that is, the output voltage rises slowly after the power is turned on, and if the tesla is turned on before the voltage rises to 15v, it will not start due to insufficient starting voltage, resulting in the triode is turned on to ground to burn the components.
the magical tesla coil generates high temperature and high pressure plasma, can ignite, can wirelessly transmit electricity, can illuminate led, manifold, energy saving lamp, etc., can connect mp3, computer, mobile phone audio through audio cable, let the arc sing and play music, while watching a small arc that can be rotated, a lot of fun, very interesting scientific experiment small production.
