What are the effects of the electronic load’s input capacity?

Each electronic load has a certain input capacity (see technical data). This is hardly noticeable with clean DC input voltages.

However, if the voltage at the load input is superimposed with an AC voltage component, the load current also contains an AC current component depending on the amplitude and frequency of the AC voltage. This is not an oscillation of the electronic load.

If the amplitude portion or the frequency of the AC voltage component is high, an overload of the input capacity can occur!

The accuracy values given in the technical data apply for clean DC voltages at the load input.
