1. Technical description.
1.1. General description.
Stabilized DC power supply is intended for supply any LAN devices through Ethernet Cable, which require stabilized voltage
of 48V DC. The unit provide power through 4/5pins(+) and 7/8pins(-) in Ethernet cable that according to the Ethernet standard are
not used to transmit data (data communication is made using pairs: 1/2 and 3/6). The Power supply can’t be used in Gigabit
Ethernet! The unit is protected against short-circuit and overload.
