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 24 V 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.
