Description

The SDIP-12-240 PoE adapter is an advanced power solution designed by the renowned Polish manufacturer ATTE. This device functions as a step-down voltage converter, drawing power directly from a 48V PoE line and delivering a stabilized 24V voltage at the RJ45 output. It is an essential product for professional network installations where there is a need to integrate devices requiring the 24V Passive PoE standard (such as Ubiquiti or MikroTik access points) with modern switches operating in the 802.3af or 802.3at standard.

A key advantage of the adapter is full support for the Gigabit Ethernet (10/100/1000 Mbps) standard. Thanks to this, the device does not limit network throughput, which is critical when transmitting large amounts of data, e.g., in high-performance radio bridges or high-resolution IP monitoring systems. The compact housing made of durable polycarbonate allows for installation in very limited spaces, such as junction boxes or camera mounts.

Product advantages:

- Stable voltage conversion from 48V to 24V without performance loss.

- Gigabit Ethernet support ensuring maximum data transmission speed.

- Wide input voltage range from 35V to 56V DC.

- Built-in LED indicating correct operation and presence of output voltage.

- Integrated surge protection protecting connected equipment.

- Very low weight and miniature dimensions facilitating discreet installation.

- High quality of workmanship confirmed by a 3-year manufacturer's warranty.

- Product fully compatible with Passive PoE and the 802.3af standard.

Software

The device operates fully automatically in the physical power layer (Plug&Play). It does not have a built-in operating system or a manageable interface, which eliminates the need for configuration. The device logic is responsible for automatic stabilization of the output voltage and lossless transmission of data packets in the Gigabit Ethernet standard. No need for firmware updates ensures trouble-free operation in continuous 24/7 mode without the risk of software interface freezing.
