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.

How to choose a poe power supply splitter?
1. Look at the appearance: The performance of a device that looks beautiful from the outside is not necessarily good, but the performance of a device that looks bad from the outside is not much better. The mature products of excellent manufacturers must be beautiful and standardized in production.
2. Look at the performance: The main technical parameters of the high-quality poe power supply splitter support both PoE standards and IEEE802.3af and IEEE802.3at power standards; the power mode supports 12/36-pin power supplies and 45/78-pin power supplies, 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: disassemble to see if the components inside are placed properly and the circuit design is smooth and tidy. The interior design of a good product will give people a pleasant feeling, and there should be a lot of protective devices, while the interior of a poor product is messy and 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.
