DC - DC Converter, 24-48 vdc Input, 802.3af/at, Output 56vdc 70 to 90 Watt, DIN Rail Mount, MADE IN USA
AIR802® part number PDCPOE4870AT is a DC to DC converter with power-over-Ethernet or PoE output. This model has a 24 to 48 vdc input range and a 56 vdc PoE output with 70 to 90 watt support. It is DIN rail mountable. This unit supports IEEE 802.3af and 802.3at. Manufactured in USA.
The model PDCPOE4870AT is a DC to DC converter with power-over-Ethernet (PoE) output. This product was designed and manufactured in the USA by AIR802 for use in applications where between 24 to 48 vdc voltage input exists and the equipment being installed requires IEEE 802.3af or 802.3at with 56 vdc and 70 to 90 watts. This model is designed for DIN rail mounting. AIR802 offers short sections of DIN Rail mount for our customers.
There are two shielded Ethernet jacks on the top of the device. One jack is labeled, "Network" for network connectivity and will ordinarily connect to a switch, router, computer or other device as desired. The other jack is labeled, "Equip + PoE" and is the output jack with 56vdc to the powered device (PD).
This model detects and automatically supports 802.3af/at over 4 wires (pins 4,5 and 7,8) and all 8 wires (Gigabit). See chart at bottom of page all supported modes and pinouts.
For applications which do not use 802.3af or 802.3at power-over-Ethernet, we offer several models with passive voltage flow.
Applications:
• Wireless access points
• Surveillance cameras including Axis cameras
• IP telephones
• Transportation sector: automobile, truck fleets, buses, trains
• Marine: ships, yachts
• Industrial: oil and gas wells, wireless service providers
• Any scenario where 9-36 vdc input is available, whether from solar panels or other sources and
output requirement is 802.3af or 802.3at with 70 watts or 90 watts with 24vdc input
