Why are POE spliter's prices so different from different manufacturers?

Why are POE spliter's prices so different from different manufacturers?

The two most important components of a PoE splitter, and also the two most expensive components, are the transformer and the poe splitter chip, which directly determine the quality and price of the device. The following is the equipment selection and characteristics of the poe power supply separator of Foshan switching power supply manufacturer:

Non-isolating transformer diodes: cheapest, unprotected cameras and poor compatibility

Isolation Transformer Diodes: Inexpensive, Poor Camera Protection and Compatibility

Non-isolation transformer standard partial discharge chip: moderate price, unprotected camera, good compatibility, easy to mislead customers

Isolation transformer standard partial discharge chip: high price, camera protection, good compatibility, the best PoE module solution.

How to choose a poe power supply splitter?

1. Look at the looks: A device that looks good from the outside doesn't necessarily perform well, but a device that looks bad from the outside doesn't perform any better. A well-established product from a good manufacturer must be aesthetically pleasing and standardized in production.

2. Look at the performance: the main technical parameters of the high-quality poe power supply splitter support both the PoE standard and the IEEE802.3af and IEEE802.3at power standards; the power mode supports 12/36-pin power and 45/78-pin power, using isolation design. These conditions must be met at the same time to become a standard POE separator to ensure the stable operation of the product without causing damage to external equipment.

3. Look inside: Take it apart to see if the components inside are properly placed and the circuit design is smooth and tidy. Good product interior design will give people a pleasant feeling, there should be quite a few protection devices, while the poor product interior is chaotic, the materials used are extremely simple. Comparing the above two pictures, we can see that although the functions are not much different, the design materials are quite different.
