4.1 Operation example in constant voltage mode
HVA4321

Figure4-2. Constant voltage mode (load mode)
lamp : Output current of high voltage amplifier
lint : Leak current with internal capacity
lout : Output current
lstr : Leak current with wire capacity
lload : Load current
lac, ldc : DC and AC of detected current
In load mode, only load current is directly detected. The current monitor can monitor load current only.
In load mode of constant voltage mode:
○
Advantage
・ Only load current can be monitored.
○ Disadvantage
・ One end of load cannot be directly grounded. There is a current detection resistance
(33 Ω ) between load end and ground.
・
The voltage of output current x current detection resistance (33
Ω
) for set output voltage is an
error in load. (When the load current is 10 mA, the error is 330 mV.)
