The appearance of the product shall be subject to the product you received. Please forgive us for not informing you again if there are any technology or software updates on our product.

WARNING:
- ELECTRICAL SHOCK AND FIRE HAZARD! Failure to comply with this instruction could result in an electrical failure, fire and electrocution.
- This equipment is a high-voltage device. Please do not attempt to disassemble it at any time to avoid danger. After a device failure, if the external switch fails to restart the device, don’t hesitate to contact your reseller for handling.
ATTENTION
The voltage input range of this product can be selected by a toggle switch; please check that the voltage of the mains and the switching voltage of the product should be consistent before powering on.
Product Parameters

Instructions for Use of the Voltage Converter Transformer
Set the product’s input toggle switch to a position consistent with the mains voltage (as shown in the figure below).
- Set the product’s input toggle switch to a position consistent with the mains voltage (as shown in the figure below). The input voltage is 220V- 240V. Rule: Switch to position 220. The input voltage is 100V-120V. Rule: Switch to position 110.
- Insert the input power cord into the end of the product, then insert the power cord plug into the mains outlet.
✮Note: Before plugging in the mains, please check whether the position of the input voltage transfer switch is consistent with the mains voltage.
- Please use the load according to the voltage of the panel output socket; the load power must be less than the nominal power of the device, and the recommended load power is 80% of the rated power.
✮Because the equipment itself has a certain loss, the load-use power must be less than the nominal power of the equipment; otherwise, there is a risk of damage to the equipment.
- The panel USB output port outputs 5V/1.5A DC as an emergency to charge other smart devices.
Notes
This equipment is equipped with an overcurrent fuse (SV-500VA or SV2000VA), which will blow when the load exceeds the equipment’s load. When you find that there is no output, check the replacement fuse.
The voltage converter transformer has an overload protection switch. When the load exceeds the load of the equipment, the overload protection switch will automatically spring up and disconnect the output. When the load overload is solved, you can press the overload protection switch by hand to open it and resume work.
This equipment is equipped with an air switch. When the load is overloaded for a long time or short-circuited, the air switch immediately turns off the output, thereby protecting the equipment from damage. When the load fault is lifted, close the air again and open it, and it can work normally.
