Revolving light current - buck convertor

[morphingstar]

Hi! Can someone explain to me what the following could mean, found in a buck convertor description:
_
Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times.

I have absolutely no idea. I saw that too and I expect it is due to a very poor translation from Chinese to English.

I would probably search for a similar product that has a better English explanation.
