My order arrived on time. Checked - works. Very useful thing, if you need universal power supply with current and voltage regulated output. I applying it as just for 12V light installation at e-vehicles ;-)
Do not buy from this seller. The product (DC-DC converter) does not work. Cannot get voltage lower than 16v with input voltage at 35V. The seller asks for help from a friend, but I am an electronics engineer. The seller does not answer my questions and does not want to refund me. Do not buy from this seller
