1. Technical description.
1.1. General description.
The PSU is designed for supply of up to 16 cameras IP requiring stabilized voltage of 48V DC.The output
voltage can be adjusted with a potentiometer between 41V÷56V DC. The power is carried over the spare pairs (4/5 &
7/8), which, according to the Ethernet network standard, are not used for data transmission (data transmission
uses 1/2 and 3/6 data pairs). The PSU is housed in a metal enclosure with signaling panel equipped with a
microswitch indicating door opening (front cover).
The PSU can not be used in Gigabit Ethernet networks, where all twisted pairs are involved in the
transmission of data!
