Important Notes

  • This product is a transformer only. It cannot directly step up 12V or 24V DC by itself. A suitable inverter driver circuit is required.
  • Common driver ICs for this type of push-pull inverter design include TL494 and SG3525, used together with suitable MOSFETs, gate-drive components, and protection circuitry.
  • The listed output voltages are based on winding turns ratio and typical push-pull operating conditions. Actual output voltage may vary depending on input voltage, duty cycle, switching frequency, MOSFET losses, wiring resistance, load conditions, and circuit design.
  • Rectified no-load voltage may be higher than the nominal voltage due to switching spikes and leakage inductance. Proper snubber circuits, filtering, 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.
