Instructions for use:
The current is unregulated and maximum is 40A. The actual current is determined by load.
Any devices below 40A current can use this product. Any devices above 40A current cannot use this product.

Note:
Before using, please select the input voltage 110V/220V according to your local voltage, to avoid damaging, switch is at right side of the item.

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. Otherwise you need to allocate the soft starting protection circuit for the load to absorb the impact current.
