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 120V Input current: Less than 1A Output voltage: Less than 20KV Output current: Less than 20mA Rated power consumption: Less than 15W Rated frequency: 20KHz~400KHz Short time limit operating parameters: Input voltage: Less than 150V Input current: Less than 8A Output voltage: Less than 20KV Output current: Less than 60mA Power consumption: Less than 15W Frequency: 10~800KHz Driver board parameters: Model: Second generation single-tube flyback driver board Input voltage: DC 5V~15V Input current: Less than 5A Power: Less than 70W Frequency: Less than 26kHz Please 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!
