PoE surge protector 48VDC

SUG-7/48VDC - PoE power line surge protection 48V DC, power supply surge protection, 48V surge protector

The SUG-7 / 48VDC is designed to protect 48V DC powered electronic devices from lightning, overvoltages, and sudden power surge that may result from power supply failure. The built-in 1A auto fuse reduces the risk of damage to the power supply and the risk of fire in the event of a short circuit in the wires or the connected equipment.

The protection features removable screw connections for easy installation and service.


Can be used with any electronics powered with 48VDC, cameras, switches and other PoE-using devices.

Simplified block diagram

To provide effective protection against lightning, it is recommended to use two protective devices and to change them. Connect one of the devices as close as possible to the power source and the other as close as possible to the receiving device. Make sure the side of the SUG-7 INPUT (LINE) side is always on the side of long wires where the overvoltage.
