- The board belongs to high frequency square AC output; it is not suitable for the inductive appliance, such as motor, fan and coil transformer.
- While picked up with low-load machines (LED light, mobile phone charger and DVD set-top box), you are suggested to pick up with low voltage point, such as: 172V/110V.
- You should install a large heat sink to release its long time high-load (¡Y100W) work.
- You could not connect the power inversely. Besides, power supply and power wire should have large enough current.
- Do not overload and short-circuit because it without any protections.
- The number in measured by the output high frequency non-load voltage meter will be a little higher.
