The TP-DCDC-1248-M DC to DC converters offered by Tycon Power Systems are a
low cost and high reliability solution for those requiring 48VDC Power Over
Ethernet voltage from a 12 or 24V battery system.
They have an integrated PoE injector to apply the regulated 48VDC to the CAT5
Ethernet cable. The input voltage must be between 9VDC and 36VDC.
They accept data-in to a shielded RJ45 Jack and provide data-out and PoE
power on the shielded RJ45 output jack. They work by supplying power on the
unused Ethernet pins 4,5(V+) and 7,8(V-).
They have various protections for surge, short circuit and overload. The
units have power output of 24W.
