Managed Gigabit PoE injector 5G7A
Gigabit PoE injector is a device manufactured in our company for the needs of wireless internet operators. As the only passive PoE device it can provide up to 1.5A power supply in an 1 Gbit/s Ethernet cable. This effect was achieved by using special high-current transformers for Ethernet signal lines, manufactured in Poland on our order. The power signal is introduced only on 4 lines in accordance with the passive PoE 100 Mbit/s, so the device is fully compatible with the slower LAN version.
PoE injector meets the power requirements from 12V to 56V. A practical solution is also the housing with height and depth of 1U and an optional DIN rail mounting bracket.
As an option, we have also introduced the function of remote management via LAN for switching on PoE power on each output separately and automatic watchdog function. It monitors communication with devices on given IP addresses and in the absence of a response, ICMP resets the chosen PoE output. This additional management option is realized by the Lan Controller - a device of our production, which analog input, logical input and output relay are led out on the front panel - for use according to the needs of user, e.g. detection of cabinet opening, measurement of battery voltage, turning on the fan, etc. There is also a digital temperature measurement port on the 1-Wire bus with DS18B20 sensors.
Basic features
- High current carrying capacity.
- Full bandwidth of 1 Gbit/s.
- Overvoltage protection on the supply input.
- Overcurrent protection on PoE outputs.
- Management via WWW or SNMP v2.
- Watchdog - reset of PoE output.
- 1 analog measurement input.
- 1 logical measurement input.
- Digital temperature measurement.
- Mounting in a rack cabinet or on a DIN rail.
RJ45 Ethernet connector
The RJ45 Ethernet connector is not intended for long-term current over 1A! We recommend using the highest quality RJ45 plugs - necessarily with gold-plated pins.
Examples of application
- Radio equipment support.
- For IP cameras.
- In industrial networks.
- For a smart home.
