The device is based on 4 interchangeable 4-channel modules housed in a single housing. This ensures their trouble-free replacement in case of failure or the use of modules from different series to adapt to the needs of the installation.
ly is a plug with a screw terminal for powering cameras using the PoE standard. This eliminates the need for expensive PoE switches and reduces the risk of damaging the only power source, which in this case is the PoE switch.
The PoE line has independent protection of the power channels. After a short circuit or overload, the circuit is temporarily disconnected until the current drawn reaches a value not higher than the nominal value. The fuse used is a modern, multi-action element.
The housing of the patch panel has special protrusions designed for securing LAN cables with cable ties. Additional holes allow the use of double cable ties for each wire, which increases the mechanical strength of the connected cables.
Panelis paredzēts montāžai 19″ plaukta skapī, bet tajā ir caurumi stiprināšanai pie sienas. Pēc papildaprīkojuma vāka uzstādīšanas tas ir papildus aizsargāts pret mehāniskiem bojājumiem un netīrumu uzkrāšanos.
Usage example
Contacts 4,5 and 7,8 are used for power supply, which are connected to increase the current flowing through the protection circuit. Due to the limited power of the decoupling resistors, the maximum power of the powered devices must not exceed 8 15 W. Decoupling resistors protect the protective components from damage in the event of a prolonged overvoltage and allow for protection gradation.
Typical Pro series protection has decoupling elements in the form of special resistors, which, despite their small size, transfer high power for a long time. Heating by the flowing current causes an increase in resistance, which provides electrical decoupling between the individual protection stages. It is necessary to ensure the correct sequence of operation of low and high power protectors. Both resistors and PTC thermistors have a very high time inertia, which creates a risk of pulse generation on the secondary side of the physical layer transformer and will damage Ethernet controllers. This is caused by a sudden current pulse that occurs when high potentials equalize between individual devices. This risk occurs when end devices (IP cameras) are installed on high poles, roofs or grounded metal structures.
