POE splitter-poe splitter chip

Foshan switching power supply manufacturers tell you why the prices of POE splitters from different manufacturers are so different?
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 are the equipment selection and characteristics of the poe power supply splitter of the Foshan switching power supply manufacturer:
Non-isolated transformer diode: the cheapest, unprotected camera and poor compatibility
Isolation transformer diode: low price, poor camera protection and compatibility
Non-isolated 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.
