6.2 Analog Card (Option)
This function provides two BNC connections, one for the control voltage and the other for the
control frequency. User can input 0 - 10Vdc from outside to control the output voltage and
frequency. If user want to control the voltage, then user must to connect the external input signal
to EXT. V. When voltage range at high range, user input 5Vdc that AC source will output 150Vac.
The frequency is the same way.
Examples for formulas
Output voltage 0 - 300V:
Vout(ac)=Vext(dc) / 10Vdc × 300Vac (300V High Range)
Vout(ac)=Vext(dc) / 10Vdc × 150Vac (150V Low Range)
Output frequency 45 - 70Hz
Output frequency(Hz)= Vext(dc) × (70Hz - 45Hz) / 10Vdc + 45Hz
Output frequency(Hz)= Vext(dc) × (Max. F – Min. F) / 10Vdc + Min. F
Caution: Input voltage can't exceed 10Vdc.
