How is your Class 4 high-voltage DC power system different from Power over Ethernet (PoE)?

The main difference is that the Cence Class 4 power system can safely supply up to 450V DC, and over 100 W of power. PoE systems, on the other hand, have a limit of 100 W, or up to 60V DC. Both PoE, and the Cence Class 4 power system, are considered safe from a fire and shock perspective (according to the NEC).
