  • Because of the characteristics of the circuit of this product, the phase of the input signal is inverted and output.
  • To obtain the maximum output voltage, the following formula must be satisfied.
    I > Vmax × πf × (Cc × 1000 × 10-12) + 0.12 × 10-3
    I : Constant current value
    Vmax : Maximum output voltage (Vp-p)
    f : frequency (Hz)
    Cc : Output cable capacity (F)
