Important Notes

  • This product is a transformer only. It cannot directly step up 12V DC by itself. A suitable inverter driver circuit is required.
  • Common driver ICs used in this type of circuit include TL494 and SG3525, together with appropriate MOSFETs, gate drive components, and protection circuitry.
  • The listed output voltages are based on winding turns ratio and typical push-pull operation. Actual output voltage may vary depending on input voltage, duty cycle, switching frequency, MOSFET losses, transformer loading, wiring resistance, and circuit design.
  • No-load rectified voltage may be higher than the nominal voltage due to switching spikes and transformer leakage inductance. Proper filtering, snubber circuits, load testing, and safe measurement practices are recommended.
  • High-voltage output can be dangerous. This product should only be used by users familiar with inverter circuits, high-frequency transformers, and electrical safety.
