... Depending on the topology used, the DC blocking capacitor might be charged via the lamp(s) at the moment the lamp(s) ignite. This will cause a temporary DC current addition to the load current that might be interpreted by the UBA2015 and UBA2015A as capacitive mode switching. If this happens the DC blocking capacitor must be reduced or pre-charged ...
