5V 40A LED Display Power Supply
The YOU-YI YY-D-200-5 is listed as a 200W power supply for compatible 5V LED display equipment. Its product options distinguish 100–130V and 200–240V input ranges.
Choose the Input Option and Check the Version
Select the input option that matches the installation. These two listed ranges should not be interpreted as automatic universal input. The original photograph shows an E2 unit marked 110/220V AC with a voltage selector, while the original specification table is marked V:G. Confirm the supplied unit’s version and input setting before connection.
The product description lists MOSFET-based rectification and overvoltage, overcurrent, short-circuit and overload protection, with output recovery after the fault is cleared.

Unresolved source entries: the table combines a 100–130V input option with a 150–170V undervoltage threshold, and lists a 61–70A current limit and 10–300MHz vibration range. Do not use these entries as confirmed ratings for either input option. Request version-specific documentation where these details affect the installation.
Frequently Asked Questions
What is the output of the YY-D-200-5?
The listing specifies 5V DC, 40A and 200W. The original product nameplate also shows 5V DC and 40A.
Which input option should I select?
Choose between the listed 100–130V and 200–240V options according to the installation supply, then verify the delivered unit’s label and any selector setting.
Does this model automatically switch between 110V and 220V?
Automatic switching is not established by this listing. The photographed E2 unit shows a 110/220V selector, so check the actual unit before use.
Why does the table say V:G while the photo says E2?
The original listing contains both version markings. Their specifications should not be assumed identical; confirm the version, mounting fit and cooling arrangement for the unit being supplied.
Where can I check the current price?
Select an input option in the product selector above to see its current price and availability. Use the matching option when ordering a replacement.
