The module is dedicated to power devices with a nominal voltage of 12 V, to which power is supplied via the PoE UTP line. It allows you to lower the voltage from 48 - 56 V to 12 V. Thanks to the use of BCS-SD15 / 12/48, we can install the camera powered by a standard DC connector in places where one PoE UTP cable was used for power supply and data transmission.
