Function

Description

PoE power supply

Complying with IEEE 802.3af and IEEE 802.3at, the PoE power module is able to remotely provide power for the devices of different vendors. IEEE 802.3af supports a maximum of 15.4 W power and IEEE 802.3at supports a maximum of 30 W power.

Input protection

Input overcurrent and undervoltage protection is provided.

Output protection

Output undervoltage, overvoltage, overcurrent, and short-circuit protection is provided.

Overtemperature protection

-

Surge protection

-

Hot swapping

Supported

NOTE:

When a power module enters overtemperature protection state, take measures to lower the ambient temperature. The power module can automatically start supplying power again when the temperature falls within the normal range.
