10/100/1000M Gigabit 802.3at to Passive PoE Converter

Cerio’s POE-PC04S PoE Converter effectively allows any PoE device to become compliant with 44~57V 802.3at active PoE standards. This conveniently standardizes power management of your system by introducing compatibility of passive PoE devices with standard 802.3at switches. POE-PC04S’s hardware design includes two Gigabit Ethernet ports, and one DIP switch to 12V, 19V and 24V three range adjustable volt PoE output.

Higlight Features

      • Complying with IEEE 802.3 10Base-T, IEEE 802.3u 100Base-TX,IEEE802.3ab 1000Base-T, IEEE-802.3at PoE+ / 802.3af PoE standards.
      • PoE (PD) support IEEE 802.3at active PoE+, IEEE 802.3af PoE, Max power input support 30Watt.
      • Supports 2ports 10/100/1000Mbps Gigabit Ethernet.
      • Supports passive PoE output voltage and hot switching for 12V / 19V /24V three range adjustable.
      • With hardware protection design the device will not cause any damage while changing the voltage output during operation.
      • Up to 100 meters (328 feet) application.
      • Supports to Short-circuit Protection.
      • Plug and Play, no software required.
      • Supports desktop or wall mounting installation and multiple units combination for easy to bundles organize the Ethernet cables.


      This POE-PC04S can convert the standard 802.3af/at active PoE source to the proprietary passive PoE (power pin 4,5/7,8), in addition it can switchable the volt output to 12V/19V/24V by DIP switch. When there had a standard active PoE switch (802.3af/at) in
      the network architecture, but the PoE device (PD) is Passive PoE type, then you can use POE-PC04S to convert the PoE power form standard active PoE to proprietary passive PoE , it is very convenient and cost effective solution. It is perfect for transforming access points that use a passive PoE design into 802.3at compliant devices. Other applications also include deploying proprietary passive PoE IP cameras with standard 802.3af/at active PoE switches.

      Hot Switching protection design

      CERIO POE-PC04S uses the latest hardware hotswitching protection design, which can effectively prevent the fault caused by instantaneous switching of different voltage. The device will not cause any damage while changing the voltage output during operation. 

      ESD Protection

      CERIO POE-PC04S supports ESD, Electro Static Discharge protection includes Over Voltage protection
      and Short Circuit Protection ensuring device safety.

      Additional Benefits

      Some additional benefits of Cerio PoE Converter include cost saving, small pocket size and convenience in network planning, and higher reliability.
