YOU-YI YY-D-200-5 LED Switching Power Supply
This LED display power supply is listed with a 5V DC, 40A output and 200W rated power. The original parameter table identifies the version as YY-D-200-5 V-G, with 200–240V input and dimensions of 210 × 62 × 31mm.
The product description specifies MOSFET-based rectification and protection against overvoltage, overcurrent, short circuit and overload. Output shuts down when protection is triggered and restarts after the fault is cleared.

Data requiring confirmation: the original table lists an output current limit of 61–70A and a vibration range of 10–300MHz. These entries are retained as supplied and should be confirmed before use in a system design. The listed standards and certification names do not replace a certificate for the supplied unit.
Frequently Asked Questions
What is the rated output of the YY-D-200-5?
This V-G specification table lists 5V DC, 40A and 200W. The current range is 0–40A.
Does this version support 110V AC input?
The table on this page specifies 200–240V input. It does not establish 110V compatibility.
What are the dimensions of this version?
The listed dimensions are 210 × 62 × 31mm. Check the mounting layout as well as enclosure size.
What protection functions are listed?
The product description lists overvoltage, overcurrent, short-circuit and overload protection, with restart after the fault is cleared.
Is this the same as every other YY-D-200-5 power supply?
Do not assume that it is. This page uses the V-G specification table. Compare the full version, input range, dimensions and connections with the replacement unit.
