The same is 8-12 W transformer, why the price difference so much?

Many customers, when building an 8–12W isolated drive power supply , encounter a problem: since these are all transformers and they look roughly the same externally, why do their prices differ so much？

The difference is not just in the materials, but in the maturity of the programmes.

   An 8–12W transformer is not judged solely on its appearance or materials。A mature platform can reduce the costs associated with repeated prototyping, EMC corrections, and specialized customization—thereby enabling projects to be completed more quickly, more reliably, and with greater ease in cost control.

Why not choose 8-12W power section?

In the power range of 8–12 watts, this type is widely used in products such as tube lights, spotlights, cabinet lights, and commercial lighting。Although the power level appears to be low, it still imposes very strict requirements on a transformer’s consistency, EMC, temperature rise, and cost control .

If the transformer selection is not suitable, it is easy to make the project into a customized model by sampling and testing back and forth. The cost of custom models is high, EMC is changed repeatedly, the cost can not be pressed down, and the batch stability is easy to be insufficient.

Repeat the prototype.

The selection was inappropriate, the verification cycle was longer, and the project progressed slowly.

EMC has repeatedly changed

The structural and parametric platform is immature, and the cost of rectification increases.

The cost can't go down.

Specialized custom models lack a common platform, and the volume cost is difficult to optimize.

Volumes are unstable

Consistency, warming, and reliability were inadequate, and subsequent delivery risks were higher.

EE1340 series mature application platform

Watt for 8-12 W isolated driver, has formed a mature EE1340 series application platform.

Instead of simply making a transformer, we do mature matching around the power needs of this power segment.
