The HVA4321 10 kV AC/DC amplifier is a constant voltage/constant current amplifier capable of ±10 kVpk and ±10 mApk. Since the unit has a DC bias signal source, it can be used as a DC power supply that is individually capable of high voltage output. Since external AC signal and DC signal input are allowed, it can also be used as an amplifier capable of high voltage output.
