VTNS2003B-2 - 2 wire switch

Switch for powering DAHUA outdoor units and monitors, intended for a 2-wire system. A maximum of one VTO series outdoor unit or up to 6 VTH monitors can be connected to one switch. In the case of a combination of 1x VTO + VTH (the consumption of all connected devices + the consumption of the switch itself must not exceed the maximum load of the power adapter for VTNS2003B-2). The possibility of connecting up to 10 VTNS2003B-2 switches in a cascade. The maximum distance at which VTO or VTH can be connected varies depending on the type of cable - when using a UTP min Cat5E cable, it is a maximum of 30 meters, with a 2x1 mm2 cable, it is a maximum of 50 meters. If it is necessary to connect several VTO and VTH to one system, it is necessary to use several VTNS2003B-2 switches, interconnected in a cascade. Cascade cabling can be implemented with two wires (e.g. between floors). A maximum of 10 switches can be used in one system. The VTNS2003B-2 switches work with a voltage of 48 V DC. Individual switches with other IP devices | and VTNS2003B-2 switches with each other | can also be connected via a LAN network. The switch is equipped with two DATA ports with an RJ-45 connector. The system works with a 48 V DC power supply. The power supply is not part of the package - it must be ordered separately.
