Note:
1. This product can work normally only when the input voltage is AC 110V or AC 220V, make sure that the local Using voltage is AC
110V or AC 220V before you place an order.
2. The default input voltage is AC 220V, 110/220V is selected by switch on the side of the device, before power on please check input
voltage avoiding damage.
2. The max current is 10A/15A/20A/40A, so any device with less than 10A/15A/20A/40A current can be used, any device with a current
10A/15A/20A upper cannot be used.
3. When using inductive loads such as motors and fans, please pay attention to the large starting current parameters of the motor, which
should not be higher than the large operating current of the power supply, otherwise the power supply may be damaged. The power supply
with larger current should be selected, or the motor should be equipped with soft starting protection circuit to absorb shock current.
