i had this tested and tested on 24 volt line for up to 10 amps but it is dubbel on the 12 volt side. i should have been more careful with testing because its was working fine but at 7 amp it was to much at the 24 volt side. we had an interesting discussion with this seller and its the best communicator i ever had on aliexpress thanks for helping me out and sending me a new one of twice the size for the price of the small one. we recommend this seller anytime!
will give update once connect
