Review on 24V AC to 12V DC Power Converter - Maximum 1.5A Output by Corey Randolph

This device has three connections on the input side. Three! They are painted black, gray and white. Completely non-standard color codes. And the device comes WITHOUT INSTRUCTIONS! The seller's website also has no instructions that I could find. No matter which combination of the three input connections I activated, a zero direct current voltage appeared at the DC output. So it will be returned. Anyway, CHINA! I get it. I'd rather pay triple that for something professionally made in the USA. The costs associated with this faulty device are enormous. time delays. The project has been suspended. A waste of manpower and the inconvenience of having to ship the suction cup back to the UPS store to get it back!
