Delivery O.K. Still not tested.
The product has been defective. It does not increase the voltage, but only lowers. Does not match what was paid, being defective. I want my money back. In the two attached photos it is possible to see that the input voltage is higher than the output: it enters 26.7 volts and I output 24.2 volts, according to the product indicator LED in F 1 EF 0. I tried to make the changes in ADJ-V and ADJ-I and only lowers the voltage, but does not increase at all.
