Hello,

I purchased a “DROK DC-DC Buck Voltage Converter 4.5-40V 12V to 5V/2A Step-down Volt Transformer Stabilizer Voltage Regulator Module” and when I plug it in to my solar cells it doesn’t turn on or output any thing. I have a 15V input which is over the minimum, is this device defective or is there a minimum input current?

I purchased a Dork DC Buck Converter for a Club Car 48 volt cart. When I try to connect the wires it sparks very bad
It did not come with a wiring diagram. Only the picture on the back of the unit. Any suggestions?

I purchased two DROK DC/DC Automatic Boost Buck Converter Modules 60W Constant Voltage/Current Car Voltage Regulators DC5-32V to 1.25-20V.

The problem is that the CC portion is not populated. The CV side is fine. The CC side does not have a pot nor does it have any components. I need desperately, what components are supposed to be there so I can buy and install them. I found some photos of a completed converter, but the images were so poor, I couldn’t make out the numbers clearly enough and I don’t want to guess.

I like to know if you have the product that take DCV input with multiple output DC voltages, 5,12 and 24V. If you don’t have the product then can you make the product?
