The TP-DCDC-1224-HP DC to DC converters offered by Tycon Power Systems are a
low cost and high reliability solution for those requiring 24VDC Power Over
Ethernet voltage from a +/-12V battery system.
They have an integrated 10/100Mb Passive PoE injector to apply the regulated
24VDC to the CAT5 Ethernet cable. The input voltage must be between 10VDC and
15VDC.
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 30W.
