  • The power module will generate heat after being energized for a period of time. Please do not touch it with your hands or body, otherwise, it may cause burns.
  • Please check whether the wiring is correct before turning on the power, otherwise, it will cause damage to the power supply.
  • When testing the insulation withstand voltage between the input and output, please short-circuit all the pins of the input and output terminals respectively and test.
  • When the product shell temperature exceeds the specified value, heat dissipation needs to be considered.
