PSE-QD
Befact Technologies launches embedded quad port PSE module, PSE-QD in September, 2008.PSE modules not only equip per port over current protection (PSE-QD, 450mA/per port) but also have total power limit protection (PSE-QD maximum total power protection, 109W). Besides, PSE-QD still provide under/over voltage protection.
Below are the key features of PSE-QD
√ IEEE802.3af compliant.
√ Per Port maximum output PSE-QD, 450mA
√ Maximum total power protection.
√ Support PD power classification from class 0 to class 4.
√ Per port over/under voltage protection.
√ Per port short circuit protection.
√ Per port over current protection.
√ Thermal cut off.
√ Equip common mode choke (per port) to reduce EMI.
√ Enhance current surge protection.
√ Per port PSE status indication.
PSE-QD can support double power mode operation (PSE-QD, 40W/per RJ45 port) for high power consumption remote device, and so do THPD& TPD module. For example, when PSE-QD & TPD-12 are applied in the same PoE link simultaneously and they are operated in dual power mode, TPD-12 can offer up to 24W to remote device.
