Varadyle ZVS Tesla Coil Marx Generator 12V-30V 20A 1000W High Voltage Power Supply Assembly Board

Varadyle #ad - About the length of the discharge arc: input voltage 12 v / 5a, when the input is a maximum of 30 V / 10 a, the higher the output power, the longer the distance of the discharge arc, the distance may exceed 5 CM.

Driving the high-voltage package with ZVS is already overloading the high-voltage package. High-voltage winding: for the primary winding, please use 1. 5mm square wire 5 turns + 5 turns that is, 10 turns of center tap in the same direction please bring your own wire. If the arc is too short, the distance of the high voltage discharge arc is about 1-2 CM. Note: light shooting and different displays may cause the color of the item in the picture a little different from the real thing.

High-voltage package: the greater the power, the better. The higher the input voltage and current, check that the input power is sufficient. Therefore, breakdown damage is a normal phenomenon, not a high-voltage package quality problem, please try not to work for a long time under high power.
