Antaira’s low voltage (12-36VDC) Power over Ethernet (PoE) unmanaged and managed switches are the most economical and efficient solution, as they accept low voltages between 12 to 36 volts to power on and supply the full IEEE 802.3 af/at PoE in a single device. This eliminates the need for a separate step-up transformer and saves space in an enclosure by only using one device.
