(Short circuit)
I peak (12) 333.33A ±10%
I peak (30) 133.33A ±10%
Rise time first peak 0.2 to 1.0 s
Oscillating frequency 100 kHz ±10%
Impedance 12 / 30 ±20%
Remark: The output impedance is calculated result of the ratio of the first peak open circuit voltage and the
first peak short current, measured with a 4000V pulse.
Typical pulses, measured with a calibrated equipment
Ringwave coupling L1 – N impedance = 30
