Turns ratio: 100 (the turns ratio is not equal to the boost ratio, usually using a flyback structure to achieve a higher boost ratio)Continuous operating parameters:Input voltage: Less than 120VInput current: Less than 1AOutput voltage: Less than 20KVOutput current: Less than 20mARated power consumption: Less than 15WRated frequency: 20KHz~400KHzShort time limit operating parameters:Input voltage: Less than 150VInput current: Less than 8AOutput voltage: Less than 20KVOutput current: Less than 60mAPower consumption: Less than 15WFrequency: 10~800KHzDriver board parameters:Model: Second generation single-tube flyback driver boardInput voltage: DC 5V~15VInput current: Less than 5APower: Less than 70WFrequency: Less than 26kHzPlease note before use: Single-pole flyback topology transformer high-voltage output must pull arc or load, no-load is prohibited! Single-tube type drive board should not work for a long time, if you need to add a fan for a long time or replace a larger radiator!Color: As ShownMaterial: Metal+PlasticPackage Contents:1 * High frequency high voltage transformerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
