In a low temperature environment of -30C, the normal starting and normal operation of the transformer will not be affected. Good low temperature characteristics are the advantages of the transformer</p> <p>It is recommended that the maximum ambient air humidity should not exceed 90%, and the monthly average humidity should not exceed 75%. In an environment with high humidity, it is recommended to use a waterproof transformer. The waterproof transformer has a protection level of IP68 and can still work for a long time even if it is immersed in water. There is currently no requirement for the altitude of the installation site for the transformer</p> <p>Note:The output thread color from batch to batch, please refer to the actual product</p> <p>Colour:As Shown</p> <p>Material:Metal</p> <p>Package Contents:</p> <p>1 Transformer</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
