Devices with Option ARC
The HV power supply is optionally equipped with an ARC Management. Figure 3: ARC Management shows the working principle
of the ARC management. The device detects an ARC when the output current is I
OUT
= (I
SET
+ 0,5 • I
NOM
). After an ARC was detected,
the control signals of the inverter are blocked within some µ-seconds for the blanking time
(ARC-Wait, t
ARC-Wait
= t1 – t0).

At the same time, the internal set value for the output voltage is set to zero. At the time instance t = t1, the internal set value of
the output voltage is increased with the voltage ramp (ARC-Ramp).
For HV sources in metal box with ARC management an ARC signal is present at pin “ARC” of the connector “AIO”. In the case of an
ARC, this signal has a low level for a approximately 1 millisecond.
HV sources in 3UC housing with ARC management are not equipped with an ARC signal.
The parameters of the ARC-Management are shown in Table 9:Parameters of the ARC Management
