1. Technical description.
1.1 General description.
Stabilized DC power supply is intended for supply LAN devices complied with IEEE 802.3 af through Ethernet Cable,
which require stabilized voltage of
37
÷57V DC.
The unit provide power through 3/6pins(+) and 1/2pins(-) in Ethernet Cable
that according to the Ethernet standard are also used to transmit data.
The Power supply can’t be used in Gigabit Ethernet.
The unit is protected against overvoltage and overload.
