Tycon Power Systems


Tycon 22-35VAC/DC IN. 56V 90W 802.3bt PoE OUT. AC/DC to DC Converter and Gigabit 802.3bt PoE Injector



The TP-DCDC-A2456GD-BT is a 5Gbps high power DCDC converter and PoE injector that accepts 22-35VAC or VDC input. It features a wide operating temperature range (-40 to +70C) and a high power 802.3bt 90W output. 

The unit has dual AC/DC inputs for maximum flexibility. The green DC connector accepts wires up to 12AWG. The “FG” input is used to provide chassis or earth ground. 

The device is fan-less and uses natural air flow for cooling. It comes with DIN rail adapters to provide mounting to a standard DIN Rail commonly used in industrial installations. It can also be wall mounted.
