50 ohm BNC output is used to monitor the real time output current accurately.
The attenuation ratio is 5mV/A-100mV/A depends on the specification
selected.
Built in Power Supply:
HVC-XXXX/QCW-USB High Voltage Switch uses a built-in a high efficient
Power Supply. In QCW mode, the output current is supplied through a huge
capacitor bank where the necessary output energy is stored. This capacitor
bank is charged and discharged at the speed of an output pulse frequency.
The load impedance for the charging power supply is changed from almost
short circuit to infinite impedance during this charging process. If the charging
power supply is not designed for this type of the load, the power supply may
have problems: such as over current trip, taking too long charging time, or
broken at the worst case.
Refer to 1.8 CAPACITOR CHARGING POWER SUPPLY for detail.
