8. High voltage
8.1. Characteristics of spray gun output voltage and current
The Inobox module has a voltage and current mapping control that limits the operation
according to curve 1.
Operator can set all the voltage / current value pairs that are including inside this curve 1.
For each UHT I
R
output current point corresponds to a maximum output voltage point, U
R
accor-
ding to a mapping recorded in the HVU and not modifiable by the user.
Example 1
: 70kV / 30µA. The operating point is inside the curve, the voltage (70kV) and current
(30µA) can be supplied if the system requires it.
Example 2
: 70kV / 80µA. The operating point is outside the curve, current will be limited to 55µA.
If electrical charge requires more current, voltage will be limited following the curve.
