I advise everyone to carefully check the quality of assembly and solders on the mounting plate. The copy that was sent to me is carelessly made. The screws securing the heat sinks have been tightened too much and one mounting hole has been torn. The bottom plate was not washed off the flux. There were little tin balls left in the flux. The ohmmeter showed that they make a short circuit between the elements. I removed the short circuits and washed the plate. Without it, the module could be damaged the first time it was connected to the power supply. Works fine after corrections. I lower the mark for careless performance and the need to correct after the producer.
