PoE, we have to figure out what it is first. Simply put, this PoE is an industrial Ethernet power supply switch that can transmit Ethernet data signals while providing power to devices in need. We have to know that it is different from our ordinary switches

First of all, its working condition adaptability

1. In terms of temperature, compared to ordinary switches. The temperature changes in the industrial environment are not a little bit. It requires PoE to work normally within a relatively large temperature range. For example, many PoEs can be started normally in cold places at minus 30 to 40 degrees Celsius, or hot places at 50 to 60 degrees Celsius. For example, ordinary exchange machines are used in offices, and it is easy to get stuck in such an environment.

2. It must also be able to resist humid environments! We know that most factories will have high humidity. PoE must withstand the interference of humidity changes. Even if the humidity reaches more than 90% of the relative humidity, it can still be in a state of operation tenaciously. Ordinary guys usually exceed a certain humidity and will damage internal electronic components.

Secondly, related to power supply

1. PoE is quite different when power supply is very powered. On the one hand, it supports traditional switches when they are often supplied with 110V or 220V AC power! Most products also provide access power supply operations for 12V DC or more commonly used in industrial industries! This greatly improves the flexibility of power supply in different industrial scenarios. In contrast, many general-purpose switches are purely docking in an energy-supply mode, and it is difficult to be flexible and flexible to combine with diversified power supply scenarios.

2. And for sudden power outages. Many good PoE products on. Setting up UPS or similar power storage equipment inside quickly provides backup power at the moment the power is terminated. Keep important equipment from missing data or abnormal shutdown caused by sudden power outages! This kind of considerate life-saving setting is usually rare on ordinary switches!

Furthermore, its data processing performance cannot be lost

1. In industrial work, the amount of data transmitted is not a limit. PoE has stronger Ethernet data forwarding capabilities. The data forwarding and processing capacity of high-end products has reached thousands of Gbps! And the ordinary switches used in home office areas are simply hard to match!

2. for more ports: It's also very important. The equipment in the factory is often connected to the same switch port with dozens or hundreds of units. PoE has many products that support up to 40 or even more than 60 physically available ports! For ordinary switches in offices, it is very rare to have such a high number of switches to 24-port.

So how to choose the PoE that suits us:

Q: How should I choose based on the industrial ambient temperature range?

Well… In fact, we have to refer to the environmental parameters provided by this manufacturer. According to the actual temperature range, we often choose a specification slightly higher than the limit temperature PoE, which is safe.

Q: What are the criteria for choosing the power supply port?

What about this… I have to calculate the power consumption requirements of the equipment connected to PoE to supply power! To reasonably confirm the port according to power requirements, you must also combine the cable laying plan in the factory. Consider these lines together, and you cannot ignore the other.

Q: What principles should be followed for switching bandwidth? ? ?

That's it… the scale of communication data in the factory determines the bandwidth capability! Evaluate the amount of data in communication and have a control range of delays. Then you can choose the switching bandwidth matching product. For example, you have big data traffic flow processing requirements such as real-time video and audio! Products with larger bandwidth are preferred.

So when it comes to this, our ordinary scenarios may focus on stable power consumption and functional satisfaction! PoE scenarios are facing the test of industrial complexity! It requires efficient and stable operation in harsh environments and under variable sudden shocks. Whether it is power supply, data transmission force, protection level, etc., it requires in-depth research and preparation in all aspects.

Provide global procurement services for weak current intelligent products! I feel that the industrial industry cannot do without the fine use of this product, so that a relatively mature and stable ecological industrial network work network can be built!
