The 30POEX_48-A signature and control circuit provides the PoE compati- bility signature and power classification required by the Power Sourcing Equipment (PSE) before applying up to 30W power to the port. The 30POEX_48-A is compatible with Class 0 to Class 3 equipment. The high efficiency DC/DC converter operates over a wide input voltage range and provides a regulated low ripple and low noise output. The DC/ DC converter also has built-in overload and short-circuit output protection. Example: 30POEX_4805-A 30 = 30 Watt; POE = Power Over Ethernet; X = S = SIP; 48 = 48Vin; 05 = 5Vout; A = Pinning Note: 1. All specifications measured at Ta = 25°C, humidity <75%, nominal input voltage and rated output load unless otherwise specified. 2. In this datasheet, all the test methods of indications are based on corporate standards. 3. Only typical models listed, other models may be different, please contact our technical person for more details. 4. Our company offer custom products. 5.
