Attention:
1.Before using, please switching the input voltage to 115V/230V according to your city voltage.115V for US, 230V for EU
2.If use motor, fan and other inductive load, please pay attention to the load's maximum starting current parameter. This parameter shall not be higher than the power supply’s max. current. Otherwise it may damage the power supply. Or allocate the soft starting protection circuit for the load to absorb the impact current.
3. High voltage inside, NEVER remove the cover. Not waterproof, indoor use only.
4. Please do not overload the devices in order to avoid damage to the equipment.
5. The max use should be no more than 80% of the full loads，otherwise, the service life of the power supply will be greatly shortened.

If there is any issue with the power supply, Please feel free to contact us. We will solve the problem for you within 24 hours.
