High-Voltage AC PCB
High-Voltage
AC transformer
Voltage input of between 0 and 12 V.
Uses this voltage to control the current value of the pre-transfer bias.
300
A
The current value of the pre-transfer bias varies as
follows according to the potential of PTDC-CNT:
3V
11V 12V
POST_DC_CNT
When '1', high-voltage DC
output is ready.
When '1', the high-voltage
AC output is ready.
When '1', high-voltage
AC output is ON.
AC output: 7.0 to 9.0 kVpp
If the current is too high
or too low, '1'.
