Embedded quad-port PSE-QD modules supply 450 mA/port and total power of 109 W. Providing 650 mA/port and 160 W, PSE-HQD units support high-power mode and are backward compatible to normal mode. Both provide overcurrent and power limit protection, support PD power classification from class 0-4 and have per port short circuit protection; thermal cut off; and common mode choke to minimize EMI. They also allow double power mode operation.
New Revolution Befact Technologies Launches PoE/PoE+ Total Solution
Befact Technologies launches embedded quad port PSE module, PSE-QD(normal power)&PSE-HQD(high power) in September, 2008.
PSE-QD and PSE-HQD are standard and IEEE802.3af compliant embedded Power Sourcing Equipment modules. Also, PSE-HQD supports high power mode. Befact puts high emphasis on safety issue, so we provide double protection mechanism to protect your design. PSE modules not only equip per port over current protection (PSE-QD, 450mA/per port; PSE-HQD, 650mA/per port) but also have total power limit protection (PSE-QD maximum total power protection, 109W; PSE-HQD maximum total power protection, 160W). Besides, PSE-QD and PSE-HQD still provide under/over voltage protection, so Befact would like to recommend you this safer and higher quality PoE/PoE+ total solution to make you feel convenient when you design.
Below are the key features of PSE-QD and PSE-HQD 1.IEEE802.3af compliant.
2.Per Port maximum output - PSE-QD, 450mA; PSE-HQD, 650mA.
3.PSE-HQD supports high power mode and backward compatible to normal power mode.
4.Maximum total power protection.
5.Support PD power classification from class 0 to class 4.
6.Per port over/under voltage protection.
7.Per port short circuit protection.
8.Per port over current protection.
9.Thermal cut off.
10.Equip common mode choke (per port) to reduce EMI.
11.Enhance current surge protection.
12.Per port PSE status indication.
Both of PSE-QD and PSE-HQD can support double power mode operation (PSE-QD, 40W/per RJ45 port; PSE-HQD, 60W/per RJ45 port) for high power consumption remote device, and so do THPD& TPD module. For example, when PSE-HQD & THPD-12 are applied in the same PoE link simultaneously and they are operated in dual power mode, THPD-12 can offer up to 42W to remote device. So Befact PoE solution is also suitable for high power consumption product to utilize.
