Kapacitní zátěže

Reliably mastering destructive inrush currents.
Loads with a capacitive load share always place extreme demands on the switching contacts – regardless of the voltage type. This applies in particular for LED lamps. When switched on, they cause high-energy current peaks that can quickly reach more than 100 A and weld the contact. But loads with capacitive components are not immediately recognizable every-where. They can also be hidden in components that are typically assigned to inductive loads - e.g. solenoid valves and contactors with an pre-circuitry to extend the input voltage range. In these pre-circuits capacitors can generate current peaks of up to 150 A when they are switched on. This can also lead to welding of the contacts or destruction of the output.
