Q: How is the output voltage calculated for a turns ratio of 69.5:1?
A: The theoretical output voltage is: Output Voltage = Input Voltage × Turns Ratio (69.5). For example, at 12V input, the theoretical output is approximately 834V. At 24V input, it is approximately 1,668V. Actual output voltage is affected by load conditions, core loss, and parasitic parameters. The 15KV is the maximum peak output capability. We recommend conducting actual measurements based on your ignition gap and medium.
Q: What are the primary and secondary winding inductance values?
A: Primary winding (Pin2-1) inductance is 12µH ±30%. Secondary winding (Pin4-3) inductance is 40mH ±10%. Test conditions are 1KHz, 0.3V.
Q: What are the primary and secondary DCR values?
A: Primary DCR (Pin2-1) is 75mΩ ±10%. Secondary DCR (Pin4-3) is 81.8Ω ±10%. The higher secondary DCR is due to the large number of secondary turns and fine wire gauge. This is a normal characteristic of high-voltage transformers.
