4.3 Operation example in constant current mode (load)
HVA4321
4-28
Figure4-34. Load mode
lamp : Output current of 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
Not all current lout from the output terminal is supplied to load. There is leak of lstr with wire capacity.
Actual current to load is lload = lout - lstr.
In load mode, lload and lstr are returned through different routes and only lload is detected to control
output current.
Therefore, Set current = lload
lout = lload + lstr
Current lout from the output terminal cannot exceed the maximum current of this unit.
In load mode, load current is directly detected. Only load current can be monitored with the current
monitor.
