10. High voltage
10.1. 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 IR output current point corresponds to a maximum output voltage point, UR according to a mapping
recorded in the HVU and not modifiable by the user.
Example 1: 70kV / 30
μ
A. The operating point is inside the curve, the voltage (70kV) and current (30
μ
A) can be
supplied if the system requires it.
Example 2: 70kV / 80
μ
A. The operating point is outside the curve, current will be limited to 55
μ
A. If electrical charge
requires more current, voltage will be limited following the curve.
