At present, the quality of isolation transformers on the market is uneven. I believe that many customers who purchase isolation transformers have doubts about whether the isolation transformers are really full power. Now we will explain and answer the doubt from the aspect of insufficient power.
(1) In terms of iron core, full-power isolation transformer is made of 16000GS imported silicon steel sheet core, which the density gap is small and the surface is smooth.
(2) In terms of copper wire, full-power isolation transformer is wound by pure copper wire. If you want to know whether the isolation transformer is pure copper wire, you can truncate the wire and observe the color of cross section. Pure copper is yellow, and The aluminum wire is gray.
(3) In terms of weight, full-power isolation transformer will be heavier. For instance, 500W toroidal isolation transformer with full power ,the weight is 4.6 KG, while it will be lighter if the power is insufficient. If you want to know the real power , that should be resort to a professional test machine.
If the power of the isolation transformer is insufficient, the transformer or mechanical equipment will be burned when it operate. On the other hand, the mechanical equipment may not be loaded. Even if the mechanical equipment can be operated, the temperature rise of the isolation transformer will be very high after working for a long time. Therefore, when choosing an isolation transformer, in addition to the price, it is recommended to consider more the actual product quality and application effect.
