Hello, the unit received a good impression, during the initial test it turned out that the shaft does not hold the pulse power to the load, we had to add electrolytes to the output stage, we need a low-current power supply circuit (220V). further tests are conducted, I will report the results with respect, Sergey A
1. The assembly of the unit is performed poorly: the thread of the housing screws is damaged. 2. The output voltage of the unit is not stabilized: at an input voltage of 180V, the output voltage decreases to 75V. 3. There is no description of the module in Russian or English, but only in Chinese.
