This product is composed of high-power driving board and UY20 transformer high-voltage power supply, output power of 500W, output voltage of 20KV. Used in industrial ignition and other high voltage power applications. The high-power driving board is not driven by ZVS, which can be used for a long time. In addition to driving the 500W transformer in the figure above, it can also drive other types of high-power transformers. Compared with ZVS, it has wider applications and stronger durability. Note: This product can not be no-load, power must have arc or load, arc distance according to transformer transformer ratio control within a certain range, non-professionals do not recommend to buy. Model2: 500W complete power supply Hign-concerned Chemical: None Type:Other Color: As Shown Material: plastic Package Contents: 1 x 500W Driver Module
