Industrial PoE+ Ethernet Switch with Power Booster
Many devices which connects to a network via an ethernet cable like machine vision systems, physical access control, VoIP phones, Wi-Fi routers and IP cameras need only one single cable for data and power if you use Power over Ethernet (PoE). This makes installation much simpler, less expensive, and easier to maintain. This helps when it comes to scaling up networks by adding new devices.
What is PoE?
Two types of devices are defined in the PoE standards. The power consumer is referred to as a Powered Device (PD). The power supplier is usually a PoE switch and is referred to as Power Source Equipment (PSE).
IEEE 802.3af (PoE) vs. IEEE 802.3at (PoE+)
The main difference between the two standards is the data transmission rate and the maximum power that can be transmitted per port.
- IEEE 802.3af supports 10 and 100 Mbit/s connections and up to 15,4 Watts per port
- IEEE 802.3at supports 100 and 1000 Mbit/s connections and up to 30 Watts per port
In addition to that you need a direct current of ~48 V DC. For PoE it is specified with 36 to 57 V DC and for PoE+ it is specified with 42.5 to 57 V DC.
Why do I need a Power Booster in a PoE+ Switch?
In industrial applications you often have a power supply with 24 V DC in your control cabinets. If you want to use a PoE Switch to power your devices you need an additional DC/DC Converter from 24 to 48 or even 57 V DC.
PoE Switches with Power Booster have this converter integrated. Usually you can power these Switches with 12 to 57 V DC. This saves space and additional equipment in your cabinet.
24 V PoE Injector
A 24 V DC PoE Injector like the UGI-501-1PoE can convert a non-PoE port to a PoE or PoE+ port. A 24 V PoE Injector is used if you need to power devices and your switch does not support PoE+. The UGI-501-1PoE 24 V PoE+ Injector has an integrated power booster.
24 V PoE Switch
A 24 V DC PoE Switch like the UGS-410-2SFP-8PoE-24V offers 8 full gigabit PoE+ Ports and ports for Fiber or Copper SFP as uplink. With the PoE Switch you can power up to 8 devices at the same time. Through the integrated power booster you can supply the switch also with 12 V DC or with 24 V DC.
