APT-3-50 3-port PoE switch 10/100/1000Mbps, extender

APT-3-50 is an gigabit PoE network switch working as an extender (repeater) of LAN and PoE power. It is most commonly used in situations where several network devices (e.g. several IP cameras) need to be run on a single UTP cable, or where an additional network branch is required. The devices combine compact dimensions with gigabit throughput.

The device allows us to power up to 2 PoE receivers via a single UTP cable. In situations where we do not have the possibility to supply a new cable or where supplying a new cable would be expensive, the APT-3-50 allows us to use the existing cabling.

APT-3-50 can act as a LAN + PoE extender in situations where the distance between devices exceeds 100m. If it is possible to split the cable into sections under 100m of UTP cable, it allows us to extend the range of the LAN without the need for an additional power supply, while maintaining full 1000Mbps throughput.

Basic applications:

• as a splitter for 2 PoE receivers (IP cameras) powered from a single UTP cable, e.g. installation of additional cameras in place of existing cameras without changing the cabling
• in cascade connection (series) for connecting several PoE IP devices at distances exceeding 100m UTP

APT-3-50 is designed to work with any network devices, IP cameras and others powered by PoE 802.3af/at.

All ports provide a throughput of 1000Mbps which is important for connections in a bus topology.

Key features and functions:

• can be powered from another PoE switch in 802.3af, 802.3at or PoE Passive standard (PoE IN port)
• amplifies and distributes the network signal (fully functional 1000Mbps switch)
• cascaded power supply (one switch powers another)
• ability to power up to 2 PoE 802.3af/at receivers
• up to 30W total power when powered from UTP
• throughput of 1000Mbps
• low power consumption (< 0.3W)
• small size of the device enables installation in small spaces, e.g. in a camera base
• easy and quick start-up without configuring parameters
• wide operating temperature range

The device has a protection level of IP20, a suitable enclosure (minimum IP44) is required to ensure protection from the elements and condensation.

If the device will be used in a small space, it is possible to cut and break the mounting brackets of the base to reduce the dimensions of the module.

APT-3-50 is equipped with a universal mounting base, which allows mounting in several ways:

• using the mounting studs on the 10.8mm grid, as used in all ABOX enclosures
• with the use of mounting studs for RACK 19" and RACK 10" adapters
• by screwing through the additional holes to any flat surface
• using additional adapter ADD-TH35 it is possible to mount the module on the TH35 rail (DIN)

Installation notes

The total power consumed by the cameras (PoE receivers) connected to the extender must not exceed the power budget offered by the switch powering the entire line:

• for 802.3af standard it is approximately 13W available on the extender
• for 802.3at standard it is approximately 25W available on the extender

Consider IR illuminators - they turn on at night, increasing power consumption significantly.

Also take into account the losses in the power cable - they depend on its cross-section, length and the voltage value on the PoE line.

Examples of applications

Example of using APT-3-50 as LAN+PoE extender for 2 PoE IP cameras.

Use of the APT-3-50 as a LAN+PoE extender for 4 PoE IP cameras at a distance of 400m.
