Original Press Release:
Befact Technologies Announces Embedded Tiny PoE PD Module
2008/11/24
Befact Technologies announces two series of Embedded Tiny PoE PD Module - High power (THPD) & Normal power (TPD). According to the output voltage, TPD&THPD series modules support three output voltage-3.3V, 5V and 12V. Embedded Tiny PoE PD Module extracts power from PSE via conventional Category 5 Ethernet cable. The application of Tiny PoE PD Module is Wireless Access Point, Access Point, IP camera, Media converter, PTZ camera, WiMax, VoIP Phone, Surveillance/Security System.
Below are the main features of THPD modules
o Isolated PD module, isolation level 1.5KV
o Backward compatible IEEE802.3af
o Support wide input voltage range, 36Vdc to 55Vdc.
o High DC/DC converting efficiency, 91% at most. The maximum output power can reach 21W(THPD-12).
o Tiny size 75mm(L)X22mm(W)15.5mm(H).
o Thermal cut off & Short circuit protection.
The output power of THPD module depends on its loading. Also, the tiny size of THPD module increases PCB utilizing space.
The main features of TPD modules are as following
o Isolated PD module, isolation level 1.5KV
o IEEE802.3af compliant.
o Support wide input voltage range, 39Vdc to 55Vdc.
o High DC/DC converting efficiency, 89% at most. The maximum output power is 12W(TPD-12)
o Tiny size 60mm(L)X19.5mm(W)X16mm(H)
o Thermal cut off & Short circuit protection.
The output power of TPD module depends on its loading, too. High DC/DC converting efficiency lowers the heat accumulation and temperature of TPD & THPD modules.
Both High Power PoE PD module and Normal Power PoE PD module are isolated PD modules, and they can be put together with the output voltage of 48V PSE which is provided by any provider. Tiny PoE PD modules support PSE Alternative A and Alternative B connections, and also provide excellent short circuit protection. THPD & TPD series modules provide the best convenience for design, because they need less external component-only one output decoupling capacitor to lower EMI.
