Tycon Power TP-DCDC4848D-HP DC-DC/POE Converter (801-TP-DCDC-4848D-HP)

Features Applications  24V and 48V Battery Systems  Wireless Access Points and Client Devices 　 IP Phone and Security Camera Systems  Input Voltage 24VDC or 48VDC  Passive POE Output voltage 24VDC or 56VDC  IEEE802.3at compatable High Power up to 35W  Dual DC Inputs for connecting 2 power sources  Integrated POE Inserter  Low self consumption power  Short Circuit Over Current and Reverse/Over Voltage Protection  High Temperature Operation DC to DC converters take an input of 36-72VDC and convert to 56V DC 30W regulated 802.3at/af POE output.They include an integrated POE inserter to apply the DC voltage to the CAT5 cable on Pins 4 5 (V+) and Pins 7 8 (V-). They have 2 isolated inputs to handle two power sources like a primary and backup source for uninterrupted failsafe operation. The input and output power are isolated so they can be used to convert a negative voltage to a positive voltage. Because of their wide input voltage and regulated output they can also be used to stabilize a voltage output. Example; a voltage source is a long distance from the equipment with wide voltage fluctuations seen at the equipment.
