The problem is that the purified power supply does not work. The manufacturer uses an electronic high-voltage power supply. Such power supply has complex circuit components that are easily damaged in high temperature and high humidity environments, so it is said that it often fails. function, it is best to ask the manufacturer to replace the power supply and use an inductive high-voltage power supply with short-circuit protection. This kind of power supply will not fail due to short circuit, the picture is as follows
