Based on the image provided, this is a power transformer, likely manufactured by Dazhong Electronic Co., Ltd. (as indicated by the text "DA ZHONG ELECTRONIC CO., LTD").

​Here is a breakdown of the technical specifications visible on the label:

​Key Specifications

​Input (Primary): 220V / 50Hz (RED-RED)

​The two red wires are the input leads designed for a standard 220V AC outlet.

​Output (Secondary): 12V / 40W (BLACK-BLACK)

​This transformer steps down the voltage to 12V AC.

​The 40W rating indicates the power capacity; at 12V, it can provide approximately 3.3 Amps of current (I = P / V).

​CQC Mark: This indicates the product has passed the China Quality Certification, which is a standard safety and quality mark for electronic components in China.
​Observations & Safety Notes

​Wiring: The label explicitly color-codes the wires. The thick red wires on the right are for the high-voltage input, while the black wires (one of which is visible and stripped) are for the 12V output.

​Condition: The wiring looks a bit exposed near the solder points. If you are planning to use this in a project, ensure that the connections are properly insulated with heat-shrink tubing or electrical tape to prevent short circuits.
​Output Type: Remember that this is an AC-to-AC transformer. The output will be 12V AC. If your project requires DC power (like for most electronics or LED strips), you will need to add a bridge rectifier and a smoothing capacitor to convert it.
